RFP SOFTWARE

RFP & Security Questionnaire Tools

Sales engineering workspace connecting demo environments, CRM, discovery notes, product knowledge, collaboration, ROI calculations, and analytics

Answering the same 200 questions for the fifth time this quarter is still one of the biggest time sinks in presales. These are the tools built to fix that.

THE TOOLS

RFP & Security Questionnaire Tools

Loopio

β˜… 4.6 (813 reviews)

The category pioneer. Reusable content library plus generative AI drafting, built for large multi-team RFP orgs with heavy review/approval workflows. Three tiers (Foundations, Enhanced, Enterprise), none publicly priced. If your org runs a lot of RFPs through a lot of hands, this is the deepest workflow tool on the list.

Users like

  • Ease of use is the single biggest praise theme, 235+ mentions
  • Strong content library and collaboration tools

Users flag

  • Word doc import and formatting problems
  • Weak internal search, stale content in the library

Pricing: Not public.

Best for: Mid-Market

Responsive

G2 Leader
β˜… 4.5 (1,312 reviews)

Formerly RFPIO, renamed in 2022. Direct Loopio competitor with a similar AI answer-engine. Custom/enterprise pricing, not public. Recently acquired Bidhive to expand into APAC bid management, so it's the stronger pick if you sell into Australia or Asia-Pacific.

Users like

  • Intuitive interface, 340+ mentions
  • AI features β€” Smart Search, Ask, AI drafting β€” plus strong import tooling

Users flag

  • Steep learning curve for new users
  • Non-intuitive text formatting and navigation

Pricing: Not public.

Best for: Enterprise

Arphie

β˜… 5.0 (23 reviews)

Newer, AI-native challenger. Doesn't ask you to migrate into a separate content library β€” it integrates live with Google Drive, SharePoint, Confluence, Notion, and even pulls from Seismic or Highspot if you already have content there. Shows source citations and AI confidence scores, offers Zero Data Retention agreements and SOC 2 Type 2. No public pricing. Worth a look if the idea of re-platforming your entire knowledge base into Loopio sounds like its own project.

Users like

  • AI automation cuts RFP response time with transparent source citations and confidence indicators
  • Proactively flags outdated source content

Users flag

  • Review sample is still small (23 on G2) β€” not enough volume yet for reliable con themes
  • Only one Capterra review is currently available

Arphie's rating is based on a small review sample (23 on G2) β€” worth confirming with the vendor directly.

Pricing: Not public.

Best for: Not shown

Tribble

G2 High Performer (vendor-reported)
β˜… 4.7 (~150 reviews)

AI RFP and DDQ automation that claims to learn which proposals actually win, not just which ones get submitted. Also runs a dedicated financial-services/DDQ offering. Fast-rising, AI-native.

Users like

  • Deep integrations β€” Slack, Salesforce, Gong, Confluence β€” embedded in existing workflows
  • Dramatic time savings, reviewers cite weeks of work down to hours

Users flag

  • AI accuracy sometimes needs a second pass on the first draft
  • Limited customization, can lag on complex queries

Pricing: Not public.

Best for: Enterprise

SiftHub

β˜… 4.5 (68 reviews)

AI RFP software / deal orchestration platform. One of the few in this category that actually publishes pricing tiers on its site instead of gating everything behind β€œcontact sales” β€” worth noting if pricing transparency matters to you when evaluating vendors.

Users like

  • Reviewers cite reclaiming 8+ hours a week
  • Real-time AI call assistance surfaces deal-aware answers live

Users flag

  • Rated on the pricier end by reviewers
  • One of the few in this category that publishes pricing tiers instead of gating everything behind 'contact sales' β€” a plus if transparency matters to you

Pricing: Publishes pricing tiers on its site.

Best for: Mid-Market/Enterprise

A note on Trustpage: if you're looking for a place to just host your security answers so prospects can self-serve instead of sending you a questionnaire, that's a different category β€” Trustpage (now part of Vanta) does trust-center pages, not active questionnaire answering.
