The problem
Security reviews don’t kill product. They kill deals.
You win the demo. Then procurement asks for proof — SOC 2, insurance, a 200-question form, evidence screenshots. Weeks pass. The champion goes dark. Legacy tools cost more than your first hire.
200+
questions in the average questionnaire
Copy-paste from last time, hunting through Drive folders, guessing at policy versions. Then doing it again for the next buyer.

Vanta, Drata and consultants solve this for larger companies. Small teams are priced out — until now.

From the field
Founders who stopped losing deals to paperwork.
“Our Fortune 500 prospect sat on a 210-question form for six weeks. With Proofline we sent it back in one afternoon — citations and all. Deal closed.”
Sarah Kim
CEO, B2B analytics (32 people)
Sample story for illustration
“I used to pay a consultant $4k per questionnaire. Now the draft is 90% done when I open it. I review, not rewrite.”
Marcus Lee
CTO, fintech infrastructure (48 people)
Sample story for illustration
“The vendor portal ended the email threads. Buyers check our SOC 2 status themselves. My calendar got a day back per week.”

FAQ
Straight answers, no fine print.
Upload your policies, SOPs and evidence once. Our retrieval system (RAG) searches those files for each question in a client's 200+ question form and drafts an answer with citations to the source doc. Low-confidence answers and gaps are flagged so a human still approves everything before it is sent.
No — and it is not legal or audit advice. Proofline gets you 80% of the way to audit-ready: drafted answers, tailored policies and collected evidence. You still need an auditor for SOC 2 / ISO certification, but you arrive prepared instead of starting from a blank page.
Legacy tools charge $10k+ per year and are built for larger teams. Proofline is built for 5–250 person companies: tiered by headcount and frameworks, with a free autofill trial, a policy generator from a 5-minute form, and a vendor portal your customers actually use.
SOC 2 is our starting point because it is the most requested by B2B SaaS buyers. ISO 27001, GDPR and HIPAA share the same evidence base — turn one on and your controls map across all four without re-entering anything.
No. Your files are encrypted in transit and at rest, scoped to your workspace, and never used to train models. You can export or delete everything at any time. The vendor portal link shows status — it does not expose raw documents to anyone you do not invite.
That is why every answer cites its source and shows a confidence score. Reviewers see the draft next to the doc, can edit in one click, and gaps get an owner and due date in the evidence tracker. Nothing is auto-submitted.
