Best AI RFP and Security Questionnaire Response Tools for Small B2B Teams, Ranked by Published Pricing, Answer Grounding, and True Monthly Cost

AutoRFP.ai is an AI-native RFP and questionnaire platform whose defining feature for a small team is its published rate card and unlimited-users model. Official pricing shows Scale at $899 per month paid yearly for up to 24 projects per year and Accelerate at $1,299 per month paid yearly for up to 50 projects per year; Enterprise is custom for higher volumes, and all listed tiers include unlimited users, unlimited AI, SSO, 18+ integrations, ISO 27001 and SOC 2 controls, onboarding, training, and support without advertised paid add-ons. A project covers any RFP, DDQ, tender, or security questionnaire tied to a CRM opportunity regardless of question count. The trade-off is project cap risk: teams that respond to more than 24 or 50 opportunities per year hit an upgrade wall rather than paying a small overage, and some users report a steeper learning curve due to navigation challenges, limited template flexibility for evolving workflows, and difficulties handling large or complex documents.

1up is the transparent entry point for a small B2B team that isn't yet certain how many questionnaires it'll process. Its pricing page lists plans starting as low as $250 per month with a free trial and self-serve signup. Pricing starts at $250 per month and scales to $850 per month across three published tiers, with Enterprise pricing available on request, no sales call required to see a number, and plans that scale based on admin users and annual questionnaire volume, not total seats. The real limiter is volume, not headcount: the plan structure's main constraint is questionnaire volume, and at the Starter tier 12 questionnaires per year means one per month, workable for early-stage teams but a hard ceiling for regular inbound RFP flow, so teams that hit this limit mid-year must upgrade plans rather than pay per overage. Reviews on G2 also mention inconsistency in AI-generated output, an inability to address complex questions, a question-length limit, and issues maintaining brand voice.

Vanta's Questionnaire Automation isn't a general-purpose RFP tool; it's a security-questionnaire product tightly coupled to the Vanta compliance platform. It's available as a standalone product or as an add-on to an existing Vanta plan and is designed to reduce time spent on inbound security reviews. Vanta combs through a knowledge base of security documentation and previous questionnaires to generate responses, pulls a matching response through when an exact match is found, and where no exact matches exist, Vanta AI generates instant, well-cited responses for you to review and approve, tailored to your preferred answer length and tone. The catch for very small teams is the underlying compliance platform: Vanta packages Questionnaire Automation as a standalone product or as an add-on to plans like Plus (which includes 25 questionnaires per year) and Professional (which includes 144 per year), so the math only works if the certification is directly unblocking revenue. Buyers should confirm current pricing directly with Vanta because plan-level questionnaire limits and packaging change.

Arphie is one of the newer AI-native entrants and posts the strongest documented posture on trust in this field. Its standout capabilities include exact source citation on every AI answer, confidence scoring that flags which answers need review, explicit 'I don't know' signals to prevent hallucination, and a flat per-project pricing model that includes unlimited users. The platform advertises live connections to Google Drive, SharePoint, Confluence, Notion, Seismic, Highspot, and URLs, SOC 2 Type 2 compliance, and zero-data-retention enterprise agreements with model platforms. The pricing model is the reason it lands here rather than higher: Arphie doesn't publish pricing publicly, operates on a custom quote model with costs depending on team size, annual volume, and integration requirements, and uses a flat per-project model with unlimited users included per project rather than seat-based pricing. A small team can still get a demo and a quote, but the entry number isn't knowable from the public site.

HyperComply differentiates on a hybrid model: AI plus a managed human review. The vendor positions the product as making it simple for security and compliance teams to automate security questionnaire responses so they can respond in as little as one day. HyperComply imports questionnaires in any format (files or web portals) and combines generative AI with expert human reviewers to answer repetitive security questions with a stated 91% answer accuracy. The trade-off for a small team is price opacity: HyperComply doesn't publish list pricing on its own site, and third-party coverage places pricing starting around $6,000/year with enterprise pricing available for larger teams and higher questionnaire volumes. Because those figures come from a third-party review rather than HyperComply's own pricing page, buyers should confirm the current entry price and included volume directly.
