Resources

The 2025 RFP software landscape divides into legacy platforms like Loopio and Responsive, which rely on static libraries built in 2014–2015, and AI-native systems like Arphie, built in 2023 with live integrations to Google Drive, SharePoint, and Confluence. Benchmarks show the same 100-question RFP takes 17.5 hours in Loopio, 15 hours in Responsive, and only 6 hours in Arphie. Arphie users accept 84% of AI-written responses as-is, saving roughly 19 hours per RFP, while legacy platforms require 200–250 hours annually maintaining static libraries. The data shows that architectural design, not just features, drives performance, trust, and total cost of ownership in modern RFP automation.

RFP proposal software feature comparison: A side by side between Loopio, Responsive, and AI-Native Arphie

The RFP response software market has fundamentally split into two eras: pre-AI platforms retrofitting automation onto decade-old architectures, and AI-native solutions built from scratch for the modern era. This comparison reveals stark differences in how Loopio, Responsive, and Arphie address the core problems plaguing RFP teams—and why time savings claims ranging from 42% to 80%+ tell only part of the story.

Based on analysis of 2,400+ verified user reviews, industry benchmarks from 1,500+ organizations, and documented case studies, this report examines how architectural choices made years ago continue to impact team efficiency today. While all three platforms reduce RFP completion times below the industry average of 25 hours, the path to those savings—and the hidden costs along the way—varies dramatically.

The trust problem: Why outdated content in RFP software kills deals

Two of these platforms were founded in 2014-2015, built their core architecture around static Q&A libraries, then added AI capabilities 7-9 years later as external services. One was purpose-built in 2023 with AI agents at its foundation. This isn't just a technical distinction, it fundamentally changes how teams work, what they trust, and how much time they actually save.

Jake Hofwegen, VP Global Revenue Operations at Contentful, captures the trust problem: "We'd used legacy RFP software for years—but keeping the library accurate took constant effort, and people didn't trust it."

That trust gap translates directly to win rates. Sales engineers know their job depends on accuracy, not speed. A single outdated security certification or incorrect pricing detail can cost a deal worth millions.

That trust gap shows up in win rates. When sales engineers can’t rely on their RFP library, they either spend time re-checking every answer or risk sending incorrect information. In both cases, deals are lost—not because the team isn’t capable, but because the system isn’t trusted.

How content libraries decay

The content treadmill never stops. Your product launches a new feature. Pricing changes. You acquire a company. That's 50+ library answers needing updates, and nobody has time to systematically review them. Within six months, 30% of your library is quietly outdated.

Then the real problems start. You pull an answer from the library for an RFP due tomorrow. You paste it in. You submit. Three days later: the pricing you quoted was from last year's model, completely wrong. Or you described a feature deprecated six months ago, and now your prospect is asking detailed questions about something that doesn't exist.

This is the moment trust breaks. You're an SE with an RFP due in 24 hours, and you can't risk pulling outdated answers that make you look incompetent. So you bypass the platform entirely. You hunt down the Google Doc that Product keeps updated. You Slack engineering directly for current answers. You pull in SMEs who actually know what's accurate and ask them to write from scratch.

An outdated answer doesn't just waste time, it actively damages your win rate. When a prospect reads incorrect information about features or pricing, their confidence in your company drops. Multiply that across 20 outdated answers in a 200-question RFP, and you've materially hurt your chances of winning.

The unfixable vicious cycle

  1. The library decays because nobody updates it (no time, unclear ownership)
  2. Teams stop trusting it because answers are frequently wrong
  3. They work around the platform by going directly to SMEs and source documents
  4. The library decays further because nobody's using it
  5. Collaboration features sit unused because work happens in Slack and Google Docs
  6. ROI disappears while you're still paying thousands annually for shelfware

The core issue: content libraries are fundamentally reactive. They store what you've already written, but they don't pull from live sources. They don't know when your product documentation changed in Confluence, when legal updated the security questionnaire in Google Drive, or when the latest pricing sheet went into SharePoint.

When Loopio and Responsive added AI in 2021-2023, they layered it on top of this static architecture. The AI searches your manually-maintained library, it doesn't pull from the source documents your team actually keeps current. AI-generated answers inherit the same trust problem as the outdated library they're pulling from.

Teams need consistency across every customer interaction—sales calls, demos, written responses. One answer that contradicts what the account executive said raises questions about vendor credibility. The career risk isn't worth the time savings.

Trust that content is current and consistent with what the rest of the team is telling customers, that's the true differentiator. Without it, RFP software becomes shelfware.

This trust problem explains why marketing claims of 40-50% time savings often don't materialize.

Time savings deep dive: Why the same RFP takes 17.5 hours with one tool and 6 with another

Industry benchmarks establish that the average RFP response takes 25 hours to complete across 153 responses.

Loopio's 42% faster claim: The math

Loopio markets 42% faster responses based on customer surveys. Starting from a 25-hour baseline (100 questions at 15 minutes each), this translates to:

  • Before Loopio: 25 hours (15 min/question)
  • 42% faster speed: 15 ÷ 1.42 = 10.6 minutes/question
  • After Loopio: 10.6 × 100 questions = 17.5 hours
  • Claimed time saved: 7.5 hours per RFP

This represents Loopio's most optimistic scenario. For one, the most enthusiastic customers that Loopio features in their marketing material only claim a 20-40% increase. But more so, real-world user feedback reveals a more complex reality. The time savings depend heavily on library quality, and most teams report building up significant "knowledge debt" over time as library maintenance falls behind.

The initial time savings often erode as libraries become outdated. Teams find themselves spending more time verifying accuracy, tracking down SMEs for current information, and manually updating library entries, which sometimes completely offsets the efficiency gains. This maintenance burden is inherent to the static library architecture, not a shortcoming of Loopio specifically.

Responsive's 40-50% time savings claim: The reality check

Responsive markets 40-50% average time savings for SMEs based on customer feedback. Starting from the same 25-hour baseline (100 questions at 15 minutes each):

  • Before Responsive: 25 hours (15 min/question)
  • 40-50% time savings: Taking the midpoint of 45% = 11.25 hours saved
  • After Responsive: 25 - 11.25 = ~14 hours
  • Claimed time saved: ~11 hours per RFP

However, real-world migration data tells a different story. Contentful, who migrated FROM Responsive to Arphie, reported their actual experience with Responsive:

Contentful's experience before Arphie:

  • Standard 200-question RFP: 30-40 hours to complete
  • Industry baseline for 200 questions: 200 × 15 min = 50 hours
  • Actual time savings: Only 20-30% (not the claimed 40-50%)

This gap between marketing claims and documented customer experience is telling. As Ashley Blackwell-Guerra, Director of Field AI at Contentful, explained about their experience:

"We had Responsive for probably 4 or 5 years, and it's a siloed database that requires someone, mostly full-time, to pay attention to content updates. It wasn't uncommon for our team to report that a standard RFP would take them upwards of 30 or 40 hours."

Contentful switched mostly because they required someone to pay attention to content updates as their full-time job because of Responsive’s siloed database. So the 20-30% efficiency gains were mostly offset by the need for a full-time content librarian.

Arphie saves 80% time per question

As a case study, one customer who migrated from a legacy RFP platform has completed 269 RFPs since joining Arphie, a robust sample size to analyze real-world performance. How they use AI-generated answers:

  • 84% of AI-written responses accepted as-is (no edits)
  • 7% with minor edits
  • 4% with major edits
  • 3% accepted as-is from Q&A library
  • 2% unanswered questions

The time savings: If we assume that the average question takes 15 minutes to answer manually and subtract all time users spent editing/writing text, Arphie's platform saves 12 minutes per question.

Applied to full RFPs:

RFP Completion Time Comparison
RFP Size Traditional Time With Arphie Time Saved
100 questions 25 hours 6 hours* 19 hours
200 questions 50 hours 12 hours* 38 hours

*Includes answering time + review/formatting

*Includes answering time + review/formatting

Where the time savings come from:

The time savings stems from the quality of first passes, meaning the 84% of AI-written responses accepted as-is is the metric that truly matters. When teams can trust AI-generated answers enough to accept them without edits, they eliminate the verification and rewriting work that consumes hours with legacy platforms.

This stems from architecture purpose-built for AI agents—which we'll explore in detail in the architectural comparison section. When AI pulls from live Google Drive documents, SharePoint sites, and Confluence pages instead of static libraries, it generates answers teams can immediately trust and verify.

Calculating the real difference: 17.5 hours vs 6 hours

Using the industry standard 25-hour baseline for a 100-question RFP:

RFP Platform Time Comparison (100-Question Baseline)
Platform Time Saved Final Time Method
No Software 0 hours 25 hours Manual process
Loopio 7.5 hours (42% faster) 17.5 hours Static library + keyword AI
Responsive ~10 hours (40% faster) ~15 hours Static library + GPT add-on
Arphie 19 hours 6 hours Live integrations + AI agents

The gap between 17.5 hours and 6 hours represents 2.92x faster completion with AI-native architecture versus AI-bolted-on approaches. For teams completing 150+ RFPs annually, this difference compounds to 1,725 hours saved, or roughly 10 additional months of productive capacity compared to legacy platforms.

The architectural divide: Why this gap exists

The performance differences trace directly to fundamental architectural decisions made years apart.

Legacy architecture: Static libraries with retrofitted AI (Loopio & Responsive)

Loopio was founded in 2014, Responsive in 2015. Both built their core platforms around the same model:

  1. Users manually create and maintain a centralized Q&A library
  2. Questions get tagged, categorized, and organized in hierarchical structures
  3. When an RFP arrives, the platform searches the library using keyword matching
  4. Users review matches and manually copy/edit content into responses

This worked well for its era, far better than email chains and shared drives. But the architecture has inherent limitations:

The content maintenance trap: Every answer lives as a discrete entry that must be manually created, updated, and maintained. As Greg Kieran, Director of Solutions Engineering at commercetools noted about their Responsive experience: "The challenge with legacy RFP software is that you're constantly chasing SMEs to update library content. Information becomes stale quickly, and there's no good way to know if answers are still accurate without asking humans to check everything."

When AI was added (Loopio in 2021, Responsive's GPT integration in 2023), it was layered on top of this static library architecture. The AI doesn't pull from live sources, it recommends or generates content based on the manually-maintained library entries. This creates three persistent problems:

Problem 1 - Trust deficit: Users can't verify where AI-generated content came from without clicking through to library entries. As one Responsive user noted: "The AI technology has evolved, there are firmly 0 benefits the software provides. I write better quality RFPs faster using GenAI tools that cost less."

Problem 2 - Generic responses: Because libraries must serve multiple contexts, answers tend toward the bland middle. One Loopio user explained: "The library is intended to be used across everything, so responses end up generic and bland, not providing great examples of bespoke responses." 

Problem 3 - Search failure: When keyword-based search returns irrelevant results, users abandon the tool. The most common complaint about Responsive: "The search is terrible. It constantly misidentifies what I'm searching for and shows completely unrelated results."

AI-native architecture: Live integrations from inception (Arphie)

Arphie was founded in 2023 by the team that built AI products at Scale AI (working with OpenAI, Microsoft, US Department of Defense), led engineering teams at Palantir and Asana, and personally felt the pain of RFP responses in their previous roles.

The founding assumption was different: Instead of asking users to manually maintain a static library that AI then searches, connect directly to where information already lives and use AI agents to retrieve and synthesize it.

The technical architecture:

  1. Live integrations: Direct connections to Google Drive, SharePoint, Confluence, Notion, Seismic, Highspot, websites, and PDFs
  2. Patent-pending chunking: Proprietary technology for understanding and retrieving information from unstructured sources
  3. Multi-agent system: Specialized AI agents for drafting, searching, content management, and verification
  4. Transparent sourcing: Every AI-generated answer shows exact source documents, confidence levels, and reasoning

This eliminates the static library problem entirely. When marketing updates a product sheet in Google Drive, that information is immediately available to the RFP system. When legal updates terms in SharePoint, responses reflect those changes. No manual library updates required.

Steve Hackney, Head of Customer Solutions at Front ($1.7B valuation), evaluated four RFP platforms before choosing Arphie: "After evaluating numerous tools, Arphie stood out in every way. It saves us a ton of time and has become a real asset in our daily work."

The transparency features address the trust problem directly. Users can see exactly which Google Doc or Confluence page an answer came from, along with the AI's confidence score. When confidence is low, the system explicitly says "I don't know" rather than hallucinating plausible-sounding nonsense.

The compound effect: Time savings vs. maintenance burden

The architectural difference compounds over time. Consider a team's first year with each platform:

Static library platforms (Loopio/Responsive):

  • Month 1-2: Intensive library building (importing or creating 500-1,000 Q&A pairs)
  • Month 3-12: Using the system, but gradually discovering outdated answers
  • Ongoing: Scheduling review cycles, chasing SMEs for updates, adding new entries
  • Result: Time savings from reuse, but ongoing maintenance burden that partially offsets gains

One Loopio user captured this: "Libraries require constant maintenance to prevent content rot. To ensure responses are findable, users add extensive content, creating bloated libraries that become difficult to navigate."

Live integration platforms (Arphie):

  • Week 1: Connect existing Google Drive/SharePoint/Confluence (no manual library building)
  • Week 1-4: Using the system immediately with real-time information
  • Ongoing: Updates happen at source, meaning content rot or knowledge debt buildup
  • Result: Time savings from automation without proportional maintenance burden

Julian Kanitz, Sales Engineering leader at Recorded Future (acquired by Mastercard for $2.65B in 2024): "Switching to Arphie has profoundly transformed our SE team's operations. Their innovative AI-native approach has significantly reduced process times, allowing us to accomplish tasks in just a few hours that previously took days."

Performance implications

The architectural differences translate to measurable efficiency impacts:

Legacy (Static Library) vs AI-Native (Live Integration)
Metric Legacy (Static Library) AI-Native (Live Integration)
Initial setup 15–60 days building library Less than 1 week connecting sources
Content freshness Only as current as last manual update Real-time from source systems
Maintenance burden 200–250 hours/year updating libraries Minimal — AI suggests improvements
AI accuracy Limited to library content quality Accesses full organizational knowledge
User trust Must verify library entries Can click through to live source docs
SME burden Update library + review RFPs Only review RFPs (no library work)

Onboarding & adoption: 15 days vs 12 weeks vs 1 week

Time-to-value varies dramatically across these platforms, reflecting both technical complexity and organizational change management requirements.

Loopio: 15-60 days with structured methodology

Loopio's official onboarding follows a five-step methodology requiring 15-60 days depending on company size:

Timeline breakdown:

  1. Kickoff (1-2 days): Meet onboarding team, set expectations
  2. Library setup (1-2 weeks): Migrate or create 500-1,000+ Q&A entries
  3. Process mapping (1 week): Document workflows and stakeholder roles
  4. Phased training (2-3 weeks): Train admins, then contributors, then SMEs
  5. First project (1 week): Import and complete a live RFP

The library setup phase is critical. Loopio recommends starting with "as little as 100 answers" but acknowledges that library quality determines automation success. Teams must decide whether to import existing content or build from scratch by mining recent RFPs.

User reality: "The initial setup is pretty labor intensive. It took me a while to understand the best way to sort stacks, libraries, categories, and tags." Customer support is exceptional (9.7/10 rating on G2), which helps teams navigate the complexity. But the phased rollout reflects a real challenge: getting SMEs to adopt adds weeks to the timeline.

Responsive: 12-14 weeks to full adoption

Responsive's official stance is that "typical implementation timeline to upload a critical mass of reusable content and achieve a workable level of self-sufficiency is about 4 weeks." However, they note "in practice, many new customers are working on live RFPs in a matter of a few days."

The gap between "working on live RFPs" and "full adoption" is substantial. Based on the user feedback and implementation guides analyzed:

  • Weeks 1-2: Platform setup and initial content import
  • Weeks 3-4: Core team begins using the system
  • Weeks 5-8: SME onboarding and workflow integration
  • Weeks 9-14: Achieving broader organizational adoption

User feedback consistently cites adoption challenges: "It has been difficult to get SMEs outside of my department to adopt. If you are not in there using it all the time, some features come across as intimidating."

The complexity stems from Responsive's comprehensive feature set. The platform offers extensive customization options, multiple collaboration workflows, and granular permission controls—powerful for enterprise teams, but requiring significant training investment.

One user quantified their challenge: "Even with 90 users that have been enabled, less than 1/3 regularly use it." This low adoption rate despite licensing costs is a recurring theme in reviews.

Arphie: Less than one week, white-glove migration

Arphie positions onboarding as a competitive differentiator, not a necessary evil. Switching to Arphie usually takes less than a week, and your team won't lose any of your hard work from curating and maintaining your content library on your previous platform.

What happens in that week:

  1. Connect live sources (hours, not days): Point Arphie to existing Google Drive folders, SharePoint sites, Confluence spaces
  2. Import any existing library (if switching from another platform): No content loss, automated mapping
  3. Run POC on live RFP (immediate): Test on real project to see actual results
  4. Training session (typically 45 minutes): Single session for most users; self-serve for sales engineers

The Contentful team's experience validates this timeline: "The POC was about as easy as it could have been. The team ran Arphie on a live enterprise RFP and immediately saw the platform's ability to retrieve the right facts and draft high-quality, review-ready answers."

A G2 reviewer reported similar speed: "We have been able to shave weeks off our workflows and go from upload to quality first drafts in ~15 minutes."

Why this matters: For the same team doing 150 RFPs annually, an 8-week difference in onboarding (12 weeks vs. 4 weeks vs. 1 week) represents 16-44 RFPs completed during the implementation period. That's 240-660 hours of productive work that teams lose while setting up legacy platforms.

Pricing models: The cost trap of capped entitlements

All three platforms require contacting sales for custom quotes, but their underlying pricing models create dramatically different total cost of ownership scenarios.

Loopio: User-based pricing with volume discounts

Model: Per-seat pricing across four tiers (Essentials, Plus, Advanced, Enterprise)

Actual costs (from Vendr pricing intelligence):

  • Plus plan (25 users): ~$24,000/year list price
  • Advanced plan (25 users): ~$35,400/year list
  • Enterprise (50+ users): Starts ~$50,000 annually, can reach $115,200+ for 50 users over 3 years

The add-on trap: Many teams on Plus plan discover they need Advanced features ($15,000-25,000 additional). Vendr data shows "73% of Plus customers upgrade to Advanced within 18 months"—essentially requiring two sales cycles and implementation periods.

Additional costs to consider:

  • Assist Package for Plus: increases $24,000 to $51,021 (113% increase)
  • Implementation fees: $5,000-15,000 (waived in 62% of Enterprise negotiations)
  • Premium Customer Success Plan: $3,500
  • Custom reporting setup: $2,500-7,500

User feedback on pricing: "It is pricey for smaller organizations and they don't have options that really fit these groups that have smaller teams."

Responsive: Seat-based tiers with expensive add-ons

Model: Tiered subscriptions (Emerging, Growth, Advanced, Enterprise) with user limits and project caps

  • Estimated range: $40,000-$70,000 annually
  • Described by competitors as "the most expensive option in the category"

The critical pricing change: Responsive historically offered unlimited users and unlimited projects—a major competitive advantage. They shifted to capped entitlements in 2023-2024, charging for blocks of 10 users and blocks of 10 projects.

This change created massive customer backlash. One detailed G2 review captures the frustration:

"Previously, Responsive was able to consolidate the market with an unlimited users and projects model. They now moved away from this and are rapidly shifting to a model of nickeling and diming customers for blocks of 10 (both users and projects), resulting in exorbitant fees in comparison to the value the tool actually offers my company."

"Responsive failed in converting many of their customers to capped entitlements, and has inconsistent pricing and licensing in the market as a result. Other customers are paying comparable fees to my company for 2k+ users vs. the 90 that my company was allotted."

"Even with 90 users that have been enabled, less than 1/3 regularly use it."

The user's warning: "Do not sign with them longer than one year!! The technology is quickly becoming obsolete in the face of rapid AI evolution. We're on the hook wasting money over the next three years."

Add-on costs by tier:

Growth Edition adds:

  • AI Agent Studio
  • API Connector
  • Custom User Roles
  • Premium Support
  • Cloud Hosting Options

Enterprise Edition adds:

  • Content Translation (22 languages)
  • Custom Report Builder
  • Business Units (multi-division)
  • Sandbox testing environment
  • Premium Connectors

The AI Assistant is technically an add-on that "must be enabled prior to use" by contacting the account manager. While now included in base pricing (2025), Vendr data shows customers negotiating "53% discounts on their AI tool" as a separate line item, indicating it may still be priced distinctly.

Account management concerns: Multiple users report "revolving door of Account Reps who are entirely indifferent to our needs and issues."

Arphie: Project-based with unlimited users

Model: Flat rate per project with unlimited users included

This fundamentally different approach addresses the core problem with seat-based pricing: RFPs require input from many stakeholders (sales, engineering, legal, security, product, marketing, finance), but most contribute to only a handful of responses annually.

From the Contentful case study: "Kudos to the pricing model being per project and not per seat. Contentful can loop in any SME needed, without new seat purchases or access hurdles."

What's included in base pricing:

  • Unlimited users (no seat restrictions)
  • All AI capabilities (no AI add-on fees)
  • Live integrations (Google Drive, SharePoint, Confluence, Notion, Seismic, Highspot)
  • White-glove onboarding
  • 24/7 support
  • SOC 2 Type 2 compliance
  • SSO via SAML 2.0

For organizations completing 150+ RFPs annually with 20+ contributors, eliminating per-seat fees while maintaining unlimited SME access represents a cleaner product experience and transparent pricing that scales with the value Arphie creates.

No-risk trials available for qualified buyers, allowing POC testing on live RFPs before commitment.

Total cost of ownership comparison

RFP Platform Total Cost of Ownership (TCO) Comparison
Platform Annual Cost Est. Hidden Costs Maintenance Hours True TCO
Loopio $35,000–50,000 Add-ons, upgrades, implementation 200+ hrs/year library maintenance $65,000+
Responsive $40,000–70,000 AI add-ons, user blocks, premium features 250+ hrs/year library updates $75,000+
Arphie Quote-based None (all-inclusive) Minimal (AI-managed content) Dependent on pricing

Consider a mid-market company completing 150 RFPs annually with 30 stakeholders (10 frequent users, 20 occasional contributors):The maintenance hours represent a hidden but substantial cost. At $100/hour blended rate (conservative for presales and legal SMEs), 200-250 hours annually equals $20,000-25,000 in opportunity cost—work that doesn't happen because teams are updating libraries instead.

Feature comparison by customer pain points

Rather than comparing feature lists, let's examine how each platform addresses the specific problems teams are trying to solve.

Pain point 1: Finding accurate, up-to-date information quickly

The core problem: 44% of teams cite this as their top RFP challenge. Information lives across Google Drive, SharePoint, Confluence, Notion, sales decks, legal docs, and product specs. By the time it's manually copied into an RFP library, it's often already outdated.

How each platform solves it:

Loopio and Responsive both use static Q&A libraries that require manual content management and scheduled review cycles. The fundamental issue: teams must manually copy information into a separate system, then maintain it through review cycles. Users consistently report "content rot," "bloated libraries," and search that "constantly misidentifies what I'm searching for." 

Arphie uses live integrations to Google Drive, SharePoint, Confluence, Notion, Seismic, Highspot, and websites—eliminating the need for manual library maintenance entirely. When marketing updates a product sheet in Google Drive, that information is immediately available. Multi-agent AI with semantic understanding retrieves information directly from source documents. Users report: "With Arphie integrated into our internal drive and website documentation, we can drastically reduce time spent managing content."

Bottom line: Static libraries (Loopio/Responsive) require 200+ hours annually maintaining content. Live integrations (Arphie) eliminate this burden by connecting to where information already lives.

Pain point 2: AI answer quality and trust

The core problem: Generic AI outputs that require extensive editing defeat the purpose of automation. Teams need to know where information came from and how confident the AI is in its answer.

How each platform solves it:

Loopio's "Magic" feature uses NLP-powered recommendation from their static library, showing matched library entries but without explicit confidence scoring. 

Responsive's AI Assistant uses Azure OpenAI GPT to search the library first, then generates from the language model if no match exists. This external AI service carries hallucination risk when no library match is found. Limited confidence indicators are provided. Users note the feature must be separately enabled by account managers.

Arphie's AI Agents use a patent-pending multi-agent system with specialized drafting, search, and verification agents. Every answer shows exact source documents (which specific Google Doc, Confluence page, etc.) with clickable links for instant verification. Explicit confidence scores (High/Medium/Low) guide review prioritization. When confidence is low, the system says "I don't know" rather than hallucinating. Data on customer usage shows 84% of AI-written responses are accepted as-is with no edits needed.

Bottom line: Transparency is the trust differentiator. Loopio and Responsive show library matches but can't link to original sources. Arphie shows exact source documents with confidence scores, enabling verification in seconds instead of minutes.

Pain point 3: Collaborating with subject matter experts

The core problem: 48% of teams cite SME collaboration as their top challenge. The average RFP involves 9 contributors across sales, engineering, legal, security, and product teams. The real challenge isn't coordinating people, it's keeping them working inside the platform rather than reverting to email chains and Google Docs.

How each platform solves it:

Loopio provides solid collaboration fundamentals: task assignment with deadline tracking, multi-assignees per question, real-time progress monitoring, threaded comments, and multi-step review workflows. The interface earns consistent praise for its collaboration functionality.

Responsive offers the most comprehensive collaboration feature set in the category: threaded comments with @mentions, task assignments with clear ownership, automated SME notifications, built-in approval workflows, and native Slack/Teams integrations for notifications. Their Microsoft case study showcases collaboration at scale, with the platform enabling $8.5B in revenue contributions across large distributed teams.

Here's what actually happens: Despite excellent collaboration tools, both platforms suffer from the same root problem—content quality erosion. The platform's static library requires "someone, mostly full-time, to pay attention to content updates." Without that, teams start to lose trust in the quality of the answers and move offline to keep up to date with the latest information to ensure RFP win rates don’t decrease. 

This creates a vicious cycle: Static libraries become outdated → AI generates poor answers → Teams don't trust the output → Sales engineers write responses from scratch in Google Docs → Collaboration happens offline in email threads → The platform's collaboration features sit unused → Content libraries decay further because no one's using them.

The per-seat pricing model adds another layer of dysfunction. Teams play "license musical chairs," restricting access to save costs. SMEs who need to contribute once per quarter don't get licenses. Result: more work happens offline.

Arphie breaks this cycle by solving the content quality problem that undermines collaboration. Live integrations to Google Drive, SharePoint, and Confluence mean the AI draws from up-to-date sources, generating answers teams actually trust. When Contentful switched from Loopio to Arphie, they didn't just get new collaboration tools—they got collaboration tools their team actually used because the underlying content quality made the platform worth working in.

Arphie's collaboration features, granular question/section ownership, reviewer assignments, Slack/email notifications with deep links, SSO auto-provisioning for new users, work because they're built on a foundation of AI that produces 84% accept-as-is responses. SMEs receive notification, click through to their assigned question, see a high-quality AI draft with exact sources cited, make quick edits, and move on. No context-switching to Google Docs. No email threads with seven people debating the correct answer.

The unlimited users model eliminates the license barrier, but that only matters because the platform is good enough that people want to use it. As Ashley Blackwell-Guerra from Contentful noted: "We can loop in any SME needed, without new seat purchases or access hurdles". And they actually do, because the AI quality makes collaboration inside the platform more efficient than working around it.

Bottom line: Loopio and Responsive have built genuinely good collaboration features. The problem isn't the tools—it's that static content libraries create quality issues that drive teams to work offline, rendering those collaboration features irrelevant. Arphie's live integrations solve the root cause, making in-platform collaboration the path of least resistance rather than a process teams work around.

Pain point 4: Maintaining consistency and formatting control

The core problem: Multi-contributor RFPs often have inconsistent tone, style, and formatting. Final documents require extensive editing to achieve professional polish.

How each platform solves it:

Loopio provides customizable themes, export templates, and subsections support. However, export formatting is the #2 complaint with 72 reviews mentioning it on G2. Users report: "Export formatting is our biggest pain point" and "The formatting sometimes needs tweaking when exporting to Word or Excel." Template flexibility and branding controls are strong points.

Responsive offers star ratings for content quality, content moderation queues, and branded templates. Users report export reliability issues: "Formatting errors in the final exported product" and "Responsive tends to add errors to the final product." Content scoring helps maintain quality standards across the library.

Arphie ensures every AI-generated response matches your organization’s unique voice and formatting standards. Our adaptive writing engine automatically aligns tone, style, and structure with your company’s guidelines. Beyond generation, Arphie guarantees consistency from draft to export—so what you produce inside the platform looks identical when shared externally. This focus on formatting precision and brand consistency is one of the top reasons customers choose Arphie over other RFP automation tools.

Bottom line: All three provide template and branding controls. Export formatting is a big area of weakness for Loopio and Responsive. If you care deeply about writing and formatting consistency in and out of your RFP software platform, Arphie is worth looking into.

Pain point 5: Content maintenance burden

The core problem: 50% of teams report maintenance as a major challenge. Keeping libraries current requires constant SME chasing and manual updates.

How each platform solves it:

Loopio requires scheduled review cycles (monthly, quarterly, semi-annually) per category, with SMEs manually updating each library entry when information changes. Users report: "Libraries require constant maintenance to prevent content rot." The risk: "To ensure responses are findable, users add extensive content, creating bloated libraries that become difficult to navigate." The review cycle feature does automate reminders to SMEs.

Responsive requires content moderation queues for reviewing and approving changes, with manual updates to Answer Library entries. Users note: "Challenging to keep content up to date and relevant." Greg Kieran, Director of Solutions Engineering at commercetools, explained their experience: "The challenge with legacy RFP software is that you're constantly chasing SMEs to update library content. Information becomes stale quickly, and there's no good way to know if answers are still accurate without asking humans to check everything."

Arphie requires minimal maintenance because updates happen at source (Google Drive, SharePoint, Confluence). The AI proactively suggests content improvements based on usage patterns. When marketing updates a product sheet, that information is immediately available—no manual library update needed. Users report: "Save 80%+ time on content management—stop chasing down SMEs for information, and instead integrate with their data sources."

Bottom line: Static libraries create ongoing 200+ hour annual maintenance burdens. Live integrations eliminate the problem by design—there's no static library to maintain, just connections to living documents teams already update.

Biggest differences & ideal customer profiles

Loopio: The established ease-of-use leader

Biggest strength: Industry-leading customer support (9.7/10) and intuitive user experience that requires minimal training. Teams can onboard and become productive quickly with extensive training resources and dedicated Customer Success Managers.

Biggest weakness: The "Magic" AI feature is poor to non-functional depending on library quality. Users frequently report still having to revise most responses manually.

Ideal customer profile:

  • Mid-market to enterprise teams (25-100+ users)
  • Organizations prioritizing ease of adoption and exceptional support
  • Teams with dedicated proposal coordinators who can invest in library maintenance
  • Organizations with mature content that doesn't change rapidly

Not ideal for:

  • Teams expecting AI automation out of the box
  • Organizations without resources for ongoing library maintenance
  • Companies with rapidly evolving products requiring constant content updates

Responsive: The enterprise feature powerhouse

Biggest strength: Most comprehensive feature set with #1 market position for 23 consecutive quarters. Strong for mature organizations needing deep customization and enterprise-scale capabilities.

Biggest weakness: Search functionality is the most common complaint across hundreds of reviews ("The search is terrible. It constantly misidentifies what I'm searching for"). Steep learning curve, low adoption rates among occasional users, and controversial pricing model change from unlimited to capped entitlements has created significant customer backlash.

Ideal customer profile:

  • Large enterprises with a dedicated proposal team and full-time proposal managers that respond to most/all RFPs
  • Organizations requiring extensive customization, business units, and complex workflows
  • Companies that value market leadership validation and can invest in comprehensive training

Not ideal for:

  • Organizations prioritizing simplicity and fast adoption
  • Teams needing reliable, fast search functionality
  • Companies without dedicated training resources for platform complexity
  • Organizations seeking transparent, predictable pricing
  • Teams that care deeply about customer support

Arphie: The AI-native speed champion

Biggest strength: True AI-native architecture with live knowledge base integrations eliminates the static library maintenance burden entirely. Transparent AI with exact source citations and confidence scores addresses trust deficit. Fastest onboarding (less than 1 week) and documented 60-80%+ efficiency gains. Project-based pricing with unlimited users removes SME collaboration barriers.

Biggest weakness: Newest platform (founded 2023) with smaller user base and limited long-term track record. Smaller sample size of reviews makes comprehensive assessment more difficult than established competitors.

Ideal customer profile:

  • High-growth companies and publicly-traded firms with rapidly evolving content
  • Tech-forward organizations prioritizing cutting-edge AI capabilities
  • Teams frustrated with library maintenance burden of legacy tools
  • Organizations with information already structured in Google Drive, SharePoint, Confluence, Highspot, Front, or Seismic
  • Companies needing to loop in many SMEs without per-seat costs (30+ contributors)

Not ideal for:

  • Risk-averse organizations requiring 10+ year vendor track record
  • Teams heavily invested in mature, extensively customized legacy platform implementations
  • Organizations primarily focused on long-form narrative proposals (vs. Q&A-driven RFPs)
  • Companies without existing structured content in supported integration platforms

The bottom line: Match RFP software to your reality

The RFP software landscape has fundamentally bifurcated into legacy platforms retrofitting AI onto decade-old architectures, and AI-native solutions built without those constraints.

The strategic question isn't just "which tool is better?"—it's "do we want to maintain a static library that AI searches, or connect to living information where it already exists?" That architectural choice determines whether your team spends 200+ hours annually updating content or eliminates that work entirely. It determines whether AI answers require extensive verification or link directly to source documents. And it determines whether onboarding takes 2 weeks or 12 weeks.

The quality gap between AI-generated answers between solutions traces directly to decisions made in 2014 versus 2023 about how information should be stored, retrieved, and trusted. For 150 RFPs annually, that's the difference between reclaiming 1,275 hours or 2,850 hours compared to manually responding to RFPs. One gives you back 7 months of capacity. The other gives you back 16 months.

Choose accordingly.

FAQ

1. How much time can I realistically save with RFP software?

The average RFP takes 25 hours to complete manually. With RFP software, you can expect to save anywhere from 40% to 80% of that time, depending on the platform and your specific use case.

Time savings depend on several factors:

  • AI quality and accuracy - Higher acceptance rates for AI-generated answers mean less editing time
  • Content architecture - Whether the platform uses static libraries or live integrations to your existing documents
  • Maintenance requirements - Platforms requiring manual library updates add 200+ hours of overhead annually

For teams completing 150+ RFPs annually, choosing the right platform can mean the difference between reclaiming 7 months versus 16 months of productive capacity each year.

2. What's the difference between "AI-powered" and "AI-native" platforms?

AI-powered platforms were built before modern AI existed (typically 2014-2015) and later added AI features as external add-ons. These platforms were designed around static Q&A libraries that require manual content management.

AI-native platforms were built from the ground up with AI at their core (2023+). They connect directly to where your content already lives—Google Drive, SharePoint, Confluence—eliminating the need for separate library maintenance.

This architectural difference fundamentally impacts:

  • How much time you spend maintaining content (200+ hours/year vs. minimal)
  • Whether information stays current automatically or requires manual updates
  • How much you can trust AI-generated answers

3. How much does RFP software typically cost?

Enterprise RFP software typically ranges from $24,000 to $115,000+ annually, depending on your team size and feature requirements. All major platforms require custom quotes rather than published pricing.

Key pricing models to understand:

  • Per-seat pricing - You pay for each user license (can become expensive with 30+ contributors)
  • Per-project pricing - You pay per RFP with unlimited users (better for large, distributed teams)
  • Tiered plans - Different feature sets at different price points, often requiring upgrades

Hidden costs to budget for:

  • Implementation fees: $5,000-$15,000
  • Premium support packages: $3,500+
  • Add-on features (AI tools, integrations, custom reporting)
  • Maintenance labor: 200-250 hours annually for static library platforms equals $20,000-$25,000 in opportunity cost

4. How long does it take to implement RFP software?

Implementation timelines vary from one week to three months depending on the platform's architecture:

Factors that affect implementation time:

  • Whether you need to build a content library from scratch (1-8 weeks)
  • Training requirements for your team (2 hours to 4+ weeks)
  • Integration complexity with existing systems
  • Organizational adoption and change management

The implementation period represents lost productivity. For teams handling 150 RFPs annually, a platform that takes 12 weeks to implement versus one week means 16-44 fewer RFPs completed during setup—240-660 hours of productive work delayed.

5. What's a static content library and should I care?

A static content library is a separate database where you manually copy, organize, and maintain Q&A content for reuse. Think of it as creating your own internal Wikipedia that needs constant updating.

The maintenance burden:

  • Someone must manually update entries when information changes
  • Content becomes outdated ("content rot") without scheduled review cycles
  • Requires 200+ hours annually to keep current
  • Teams lose trust when answers are inaccurate

The alternative - live integrations: Modern platforms can connect directly to Google Drive, SharePoint, Confluence, and other systems where your content already exists. When marketing updates a product sheet, the RFP platform immediately accesses current information—no manual library updates needed.

This architectural choice determines whether your team spends hundreds of hours per year on maintenance or eliminates that work entirely.

6. How do I know if AI-generated answers are accurate?

The key to trusting AI-generated answers is transparent sourcing with citations.

What to look for:

  • Exact source citations - The AI should show you which specific document (Google Doc, Confluence page, PDF) each answer came from
  • Clickable verification links - You should be able to instantly open the source document to verify accuracy
  • Confidence scores - The system should explicitly indicate how confident it is (High/Medium/Low)
  • "I don't know" responses - When confidence is low, the AI should admit uncertainty rather than generating plausible-sounding but incorrect information

Without transparent sourcing, teams spend hours verifying and rewriting AI outputs, which defeats the purpose of automation. With proper citations, verification takes seconds instead of minutes, and acceptance rates for AI-generated content can reach 80%+ with minimal editing.

7. Which type of team benefits most from RFP software?

RFP software delivers the strongest ROI for organizations that:

Handle high RFP volume:

  • 50+ RFPs annually (below this, manual processes may be more cost-effective)
  • 150+ RFPs where automation becomes critical to capacity

Have distributed contributors:

  • 9+ people involved per RFP across departments (sales, engineering, legal, security, product)
  • Need to loop in subject matter experts who only contribute occasionally

Face content challenges:

  • Information scattered across Google Drive, SharePoint, Confluence, Slack
  • Rapidly evolving products requiring frequent content updates
  • Struggle with outdated information in responses

Have dedicated resources:

  • At least one person who can own the RFP process and platform
  • Willingness to invest in setup and adoption

Teams with fewer than 25 RFPs annually or very simple response requirements may not see sufficient ROI to justify enterprise software costs.

8. How do I evaluate RFP platforms for my specific needs?

The best evaluation method is a live proof-of-concept (POC) using one of your actual RFPs. Request POCs from all platforms you're considering and measure:

Answer quality metrics:

  • What percentage of AI-generated answers are usable as-is?
  • How many require minor edits vs. complete rewrites?
  • Can you easily verify where information came from?

Time measurements:

  • How long from uploading the RFP to getting a complete first draft?
  • How much time does review and editing actually take?
  • What's the total time to final submission?

Team adoption indicators:

  • Do subject matter experts trust the output?
  • Will people actually use this, or work around it?
  • How intuitive is the interface for occasional users?

Implementation reality check:

  • What does setup actually require (not just what sales says)?
  • Will you need to build a content library from scratch?
  • How long before your team is productive?

Beyond the POC, check recent user reviews (within the last 12 months) on G2 or similar platforms, focusing on complaints about search quality, export formatting, customer support responsiveness, and whether actual results match marketing claims.

The documented performance gap between platforms—some reducing a 25-hour RFP to 17.5 hours while others reduce it to 6 hours—makes thorough evaluation worthwhile.
