Inbound RFPs and security questionnaires are the quiet pipeline killer on a small B2B team. The deal is real, procurement likes you, and then a 180-question SIG Lite lands in the inbox and nobody has four days to spend copy-pasting from last year's responses. The enterprise category leaders, Loopio and Responsive, are built for proposal operations teams you don't have, and priced accordingly.
So we looked at the lighter end of the field: five AI RFP and security questionnaire tools actually sized for a 5-to-30-person B2B team. We graded them on what we checked in current official documentation and pricing pages in October 2026: entry-tier cost and what's actually unlocked at that tier, how the tool handles both long-form RFPs and short-form security questionnaires, how reviewer/SME participation is priced (seat tax vs. unlimited users), and whether a small team can set it up without a six-week implementation. This is a desk-rubric comparison grounded in each vendor's own published terms, not a hands-on bake-off.
A note on how we landed on this order, because the gap in pricing shape between #1 and #5 is wide and that deserves saying out loud.
The RFP software category is bifurcated in a way most other sales-tool categories aren’t. On one end you have Loopio and Responsive, real products that genuinely earn their keep for a mid-market team with a proposal operations function and a content manager whose job is maintaining the library. On the other end you have a cluster of newer, AI-native, usually-self-serve tools (1up, DeepRFP, AutoRFP.ai, Inventive AI) that have figured out the thing the incumbents charge enterprise money to do, and are priced for teams that don’t have a proposal ops hire. If you’re a 10-person B2B startup, you aren’t in the first group. You shouldn’t be shopping in the first group.
That’s why 1up wins this. The feature set isn’t the deepest in the field (Inventive AI has more sophisticated agent architecture on paper, and AutoRFP.ai’s portal coverage is broader) but the shape of the pricing matches the shape of a small-team workload. A free tier so you can get a feel for it. Unlimited users on the entry paid plan so the AE, the SE, the one security person, and the two founders can all participate without a seat tax. A workflow that lives inside Slack and the browser, which is where someone on a small team actually answers a security questionnaire, not inside yet another tool they’d have to open. $300/month is a budget that’s cleared by the first saved deal.
DeepRFP earns its number for a different reader. If you’re a solo proposal consultant or a two-person bid shop, you don’t need unlimited collaborators. You need a self-serve plan you can sign up for without a demo. A product that generates a first draft from your past proposals is a legitimately good deal at that scope.
AutoRFP.ai is the right call once you’re genuinely answering multiple projects a month. $899/month billed yearly feels like a lot until you compare it to the hours a two-person team was spending to grind through a monthly SIG. Inventive AI is the one to look at specifically if your knowledge is scattered across SharePoint, Notion, and Google Drive and you don’t want to build another library. The agent-and-citations architecture is a real differentiator, and the lack of self-serve checkout is the only reason it isn’t ranked higher.
And then there’s Loopio, which is a good product. We just can’t recommend it to the team this ranking is for.
A couple of other reads that go next to this one: if the deals that follow these RFPs are stalling in the proposal-to-signature step, the companion ranking of AI proposal and contract software for small B2B teams closing deals covers the next tool category down the funnel. If the reps running those late-stage calls could use coaching before and after the RFP goes out, the AI sales call coaching and deal intelligence ranking is the one to read. And one tangential but useful crossover: the same knowledge base you build in 1up or Inventive AI to answer RFPs is also what you want cited by ChatGPT and Perplexity when a buyer researches you, which is the exact job that GEO guide walks through.
One last caveat worth saying: prices in this category move. The current numbers above were pulled from each vendor’s live pricing page or official product page in late October 2026. Before you sign anything annual, re-check the rate card.
FAQ
What's the best AI RFP response tool for a small B2B team?
1up. It scored 90 on our rubric and took Editors' Choice because it's the only tool in the field with a real free tier, a $300/month Starter that includes unlimited users and unlimited answers, and a workflow built around Slack, Teams, and a browser extension. For a small B2B team without a dedicated proposal manager, that combination beats a bigger, library-first platform almost every time.
What should a solo consultant or 1–3 person bid team buy?
DeepRFP. It's self-serve, aimed at consultants and lean bid teams, and the workflow is simple: upload a past proposal, load the RFP, and get a first draft back the same day. For a one-person shop that wants a self-serve entry point without landing in an enterprise sales cycle, it's the cleanest option in the category.
Is Loopio worth it for a small team?
Usually not. Loopio is a strong product with great support, but its own site positions the Foundations tier at "10 seats … for smaller, sales-led RFP teams," with Enhanced and Enterprise packages above that and no published rate card. If you don't have a dedicated proposal manager and aren't answering a steady, high volume of enterprise RFPs, you're paying mid-market money for infrastructure a small team can't fully use.
What about security questionnaires specifically, SIG, CAIQ, custom portal forms?
1up, AutoRFP.ai, and Inventive AI all handle both long-form RFPs and short-form security questionnaires, including web-based portals through a browser extension or portal agent. If your inbound mix is mostly security questionnaires rather than narrative RFPs, 1up's Slack and browser plugin at Starter is the cheapest useful entry; AutoRFP.ai is the next step up if you're seeing more than two a month.
How did you actually score these?
This is a desk-rubric comparison, not a hands-on test. We priced the entry tier for each vendor against its current official pricing or product page in October 2026, checked documented scope (RFPs, DDQs, security questionnaires, portals), looked at how reviewer/SME access is priced, noted whether pricing is published and self-serve, and read the documented answer-quality controls (citations, confidence scores, 'information unavailable' flagging, SME routing). Five metrics, each 0–100, combined into the single number on each badge.
