Your prospect sends a 200-question Excel file. You open last quarter's Google Doc, Ctrl+F, copy-paste, then chase engineering, legal, and finance on Slack for days. At seed that's you — the CTO. At Series A–B it's still often you, while your VP of Sales asks when the deal will close. FillBase does the work in Slack; you approve and send.
Enterprise buyers won't sign until their security team approves you. Each questionnaire takes ~8 hours on average — and the deal sits in limbo until you're done. Loopio and Conveyor are for GRC teams at scale — FillBase is for the CTO or VP Engineering still owning the DDQ at a 20–200 person SaaS company.

Slack-native · Zero context-switching
No upload-and-wait dashboard. Forward a questionnaire in Slack and get a completed, source-cited file back.

Every completed questionnaire trains the knowledge base. 70-80% of questions repeat across formats — train once, answer everything.

When it's stuck on encryption or sub-processors, it @mentions the right engineer or lawyer — not another email thread you have to manage.

SIG, CAIQ, VSA, HECVAT, or custom Excel from your buyer's security team — not just the templates big GRC tools expect.
Upload SOC 2 once. Forward the next DDQ from your prospect's security team. Review cited answers and send — while your VP tracks the close.
SOC 2 report, security policies, and 2-3 past DDQ responses. FillBase ingests everything and builds your knowledge base in minutes.


Email, Slack, or upload — any format. FillBase parses every question, matches your knowledge base, and auto-completes ~90%.


Every answer has a source citation. Approve, export in the original format, and move on. The next DDQ is faster.


Stop being the bottleneck between security review and signature. Your VP gets a completed DDQ in days, not weeks.

What teams say about FillBase


“I was the CTO filling every DDQ in Google Docs at midnight. Now I forward them in Slack and review in 30 minutes — our first six-figure enterprise deal closed two weeks faster.”
Sarah Chen
CTO & co-founder, seed-stage SaaS


“My VP kept asking when the security review would finish. FillBase turned a two-week DDQ into a same-day review — we finally got the enterprise signature.”
Marcus Webb
VP Sales, Series B SaaS


“Series A with three enterprise deals stuck on DDQs I was rebuilding in spreadsheets. FillBase gave the same sourced answers every time — buyers stopped sending follow-up rounds.”
Emily Locas
VP Engineering, Series A SaaS
Slack, Excel, Word, PDF, OneTrust, ServiceNow, Vanta, Drata — FillBase connects to where your security data already lives.




























































































































































































































































Less than hiring a junior GRC analyst ($6K/mo). Trivial if it unblocks one enterprise deal your VP has been waiting on.
