Responsive vs Tribble (2026): pricing, features and verdict

Short answer: Pick Responsive if you want one platform to run the whole response operation, from intake request to e-signature, with a published starting price ($10,000 platform fee on its Emerging edition) and a choice of six AWS hosting regions. Pick Tribble if the job is narrower but wider-reaching: one governed set of sourced answers feeding RFPs, fund DDQs and the sales floor, billed per project with every contributor included. Responsive is the bigger building; Tribble is the shared answer that walks between rooms.

Responsive started in 2015 as RFPIO, with a handful of staff in Beaverton, Oregon and Coimbatore, India. It now reports more than 500 employees, nearly 2,000 customers (including more than 20 percent of the Fortune 500) and over 300,000 users, and it bought RFP360, InHub and Bidhive along the way. Tribble was founded in April 2023 by Sunil Rao, a former Salesforce VP, joined Salesforce Ventures’ Generative AI Fund that June, and pitches itself as a “governed answer layer” for proposal and sales teams.

Those starting points explain most of what follows. One vendor has spent a decade adding modules around the response. The other started with the answer and is building outward toward the sales call. All facts below come from each vendor’s own pages or dated review sites, as of October 2026.

Key takeaways

• Pricing transparency: Responsive lists its Emerging edition from $10,000 a year as a platform fee, plus user licenses and add-ons, on a 12-month minimum. Tribble lists no numbers: Respond is per project (all contributors included), Engage per user per month.
• Scope: Responsive’s Growth edition adds intake requests, LookUp and e-signature, and its AI includes a no-code Agent Studio. Tribble adds Engage, a sales assistant with a call recorder, on the same knowledge base as its RFP product.
• Residency: Responsive customers can elect AWS hosting in six regions (US, Canada, UK, Australia, Singapore, EU). Tribble publishes no hosting regions.
• Scale of proof: Responsive holds 4.5 out of 5 on G2 from 1,308 reviews (July 2026). Tribble shows 4.7 out of 5 from 175 reviews (October 2026).
• AI checks: Responsive rates each AI answer with a TRACE Score for accuracy, relevance and traceability. Tribble attaches a per-answer confidence score and runs a contradiction check across the whole questionnaire.
• Limitations: Capterra reviewers describe Responsive as heavy at first and report export cleanup. G2’s May 2026 summary of Tribble reviews flags setup issues, frequent UI changes and occasional inaccuracies.

Two definitions of “the whole process”

Both vendors say they cover the response end to end. They mean different ends.

For Responsive, the process starts when someone in sales files an intake request and ends when the buyer signs. In between sit agents that shred RFPs, DDQs and vendor security questionnaires for requirements, a patented import agent that captures tables and dropdowns, a writing agent that drafts from “trusted content and prior successful responses,” approvals, and LookUp and e-signature on the Growth edition. An Ask desktop app gives anyone in the company cited answers from the content library. The center of gravity is the response project.

For Tribble, the process starts with a buyer question, wherever it shows up, and ends when the deal closes. The question might be row 47 of a SIG, a DDQ from a pension fund, a Slack message from a rep, or an objection on a call. Respond handles the documents: drafting with sources, a go/no-go step, long-form narrative in an editor, export back to Word, Excel, PDF or a buyer portal. Engage handles the people: prepping reps, answering during calls, drafting follow-ups, suggesting CRM updates. The center of gravity is the answer itself.

The invoice: three lines versus two meters

This section decides a lot of shortlists, so here is exactly what each vendor publishes.

Responsive builds every deal from three parts: a platform fee, user licenses, and add-ons and services. The pricing page shows four editions (Lite, Emerging, Growth, Enterprise), with only Emerging carrying a figure: “Starting from $10,000.” Every edition includes unlimited response projects. User pricing is “based on who needs access,” across admins, contributors and SMEs. Add-ons named on the page include an MCP server and connectors, CRM and API integrations, security, governance and custom reporting, and premium onboarding and support. The FAQ says “a minimum of 12 months is standard,” and a proof of concept is offered “for qualifying situations.” Standard support runs 24 hours a day, Monday to Friday, excluding US and Indian public holidays.

Tribble prices two products on one knowledge base. Respond is priced by the number of projects a year, each RFP, DDQ or security questionnaire counting as one, and everyone who helps answer is included. Engage is per user, per month, with Scribe call recording included. The Brain comes with both. Single sign-on, user permissions and connected tools are listed as price factors. There are no figures: “Tell us your numbers and we’ll give you a price on the call.”

What that means for total cost:

• Volume: Responsive’s unlimited projects mean a busy quarter does not change the bill. Tribble’s Respond meter rises with project count.
• Headcount: Responsive’s licenses scale with everyone who needs access, SMEs included. Tribble’s Respond ignores contributor count entirely.
• Hidden lines: Responsive’s CRM integration is an add-on. Tribble’s SSO is a price factor. Ask both for a quote that includes the integrations and identity setup you actually need, not the headline.

With Responsive you can at least bracket the floor before the first call. With Tribble, the first call is the floor.

How each one checks its own AI

Both vendors sell AI that shows its work. The checks differ in where they look.

Responsive’s TRACE Score rates each AI-generated answer for accuracy, relevance and traceability, and the company says it validates drafts against trusted sources and highlights issues early. The Ask app returns answers with source citations. Agent Studio lets teams build custom agents in plain language from templates, which is powerful and also one more thing for an administrator to test and own. Responsive’s subprocessor list names OpenAI’s GPT for content writing assistance, which tells your security team exactly which model provider is involved.

Tribble attaches a confidence score and a source link to every drafted answer, then runs a consistency check across the full questionnaire so contradictions across 200 or more items surface before submission. Questions with no supported answer are marked as such and routed to an expert in Slack or Teams rather than filled with a guess. Tribble says customer data never trains shared AI models and each source keeps the permissions it already had. It does not name its model provider on the pages we read.

Neither vendor publishes an independent accuracy benchmark. Both quote customer speed figures; those are vendor-reported, so we have left them out. The cheap test still works: take a questionnaire you answered last quarter, plant one contradiction in your source documents, and see which tool catches it.

Data residency and the security review

If you sell into regulated buyers outside the US, this may be the deciding section.

Responsive’s subprocessor list lets customers elect AWS hosting in the United States, Canada, the United Kingdom, Australia, Singapore or the European Union, and storage follows the elected region. The same list names Google Cloud and Microsoft Azure for alternative or enhanced features. Its pricing page puts “flexible hosting options” in the Growth edition, so confirm which regions your edition includes before you promise anything to a buyer.

Tribble states SOC 2 Type II, SSO and role-based access control on its product pages. We found no public statement of its hosting provider, regions or subprocessors. Its own guidance file for AI assistants is careful in a way worth noting: it says not to describe Tribble as HIPAA compliant or certified, or as offering a BAA, even though Tribble markets workflows for answering HIPAA questionnaires. That honesty is useful. It also means a healthcare buyer’s own questionnaire to Tribble will need direct answers from the vendor.

If your buyers ask “where does our data sit?” in the first meeting, Responsive answers on paper today. With Tribble, put the question in writing during evaluation.

Size, history and what each one buys you

Responsive’s size is an asset and a cost. Nearly 2,000 customers and 1,308 G2 reviews mean you can find references in your industry and read years of feedback. Homepage quotes come from proposal leaders at Microsoft, Tenable and Haworth. The acquisitions explain the breadth (RFP360 in 2021, InHub for the investment community in 2022, Bidhive in 2025), and they are a reason to ask which modules share one content library and which feel bolted on.

Capterra reviewers point to the cost of that breadth. They describe Responsive as “a little intimidating at first” (November 2025) and “a bit heavy at times” (April 2026), and one reports “a considerable amount of extra hours cleaning up the formatting” when exporting to templates (April 2026).

Tribble is younger and smaller, with customer stories from Clari, TaskUs, UiPath, Sprout Social, BrightSign and Rightway. Its G2 standing is strong for its age. Its comparison pages need a pinch of salt, though: the Responsive page says Clari “replaced Responsive and three other tools,” while the Loopio page says Clari replaced Loopio and three others. Both may be true of a messy stack. Read them as sales copy, not case law.

Connectors, tags and the browser extension

The logos on the homepage are not the whole stack. The extras change who can live in the tool without learning a new one.

Tribble’s go-live page, checked October 2026, says you can run a first RFP before connecting anything. The connectors it then names are Google Drive, SharePoint, Salesforce, Slack, Microsoft Teams, Confluence, Box, Dropbox, Notion, Jira, HubSpot and ServiceNow. A Chrome extension powers Scribe, web capture and inline inspection of an answer. The same page’s setup steps cover tiering content by authority, with internal subject-matter answers above partner documents and partner documents above web content, plus tags for region, product line or segment. Those tags, Tribble says, drive filtered answers and the go or no-go call. Its security questionnaire page adds the file shapes that show up on a Tuesday night: XLSX, DOCX, PDF, SIG Lite, SIG Full, CAIQ and portal uploads, and it describes an answer-level audit history next to its SOC 2 Type II claim.

Responsive’s integrations page is wider on the Microsoft desktop. Excel, PowerPoint and Outlook add-ins work with AI-recommended content inside those apps. Whistic is there for vendor assessments, and a ChatGPT app brings approved knowledge into ChatGPT. Jira, ServiceNow and Gong do not appear on that page. Gong matters if the sharpest product answer was said on a call and never typed into a library.

The concession is plain. Responsive meets a proposal team inside Office and a security team inside Whistic, with a published residency list behind it. Tribble meets a sales team inside a call recorder, Jira and ServiceNow, and it will tag an answer by segment before you have hired a content admin. Buy the list that matches the tools your people already refuse to close.

Choose Responsive when

• You want intake requests, response projects, approvals and e-signature under one contract.
• Buyers require data hosted in Canada, the UK, Australia, Singapore or the EU.
• You need a published floor for budgeting and can commit to a 12-month term.
• Your volume swings a lot and you want unlimited projects so busy quarters do not move the invoice.
• You have an administrator who will own configuration, custom agents and add-ons.
• References and years of reviews from large enterprises matter to your buying committee.

Choose Tribble when

• The same security and product answers get asked in RFPs, in Slack and on calls, and you want one source behind all three.
• Your bids pull in many occasional experts and you would rather pay per project than license each one.
• You answer fund DDQs and want a compliance owner per answer plus a cross-package contradiction check.
• Gong recordings and CRM history hold answers you want drafts to use.
• You are comfortable with a younger vendor, a sales-led price, and asking hosting questions directly.

Verdict

Different jobs that overlap in the middle. Both will draft an RFP, a DDQ or a security questionnaire from your content with sources attached. Responsive wraps that core in a large operating platform with published entry pricing, regional hosting and a long enterprise record. Tribble wraps it in a sales-facing answer layer that carries the same reviewed answer from the questionnaire to the call.

If your bottleneck is running the response operation at scale, start with Responsive. If your bottleneck is answers that drift between the proposal team and the sales floor, start with Tribble. As a colleague might put it: Responsive runs the RFP department, Tribble makes sure everyone outside it says the same thing.
