AI-native data room for sell-side M&A

Vendor due diligence,
done before the buyer asks.

Upload the data room once. SellSide DD drafts the vendor DD report, consolidates legal findings and prepares buyer Q&A — every figure traced to its source document, every conclusion reviewed by an advisor.

How it works

From raw folders to a buyer-ready room.

01
Upload the data room
Drag in folders as they are. Structure is preserved; documents are indexed and summarised on our servers.
02
AI does the first pass
Summaries, red flags, legal clauses, financial tables and cross-document inconsistencies — in minutes, not weeks.
03
Advisors review & publish
Accept or challenge each finding, generate the vendor DD report and open the room to bidders with confidence.
What you get

The work of a DD team — in the data room itself.

Sellers who prepare their own diligence control the narrative, shorten the process and protect the price.

Vendor DD report in hours
Financial, commercial, legal and QoE sections drafted from the documents in the room — every statement cited to its source document, ready for advisor review.
Legal findings, not clause lists
Contract clauses are extracted and consolidated into a handful of risk themes — change of control, key-person, leases, IP — each with deal impact and the SPA protection to ask for.
Buyer Q&A, drafted and flagged
Bidder questions are answered from the data room with citations. Sensitive answers (customer names, pricing, litigation) are flagged before anything leaves your hands.
Ask the data room
Advisors and buyers ask questions in plain language and get answers grounded only in the documents they are allowed to see.
Proactive red flags
Inconsistencies between documents, gaps a buyer will ask about and QoE issues surface automatically as documents arrive.
Advisor in the loop
AI drafts, advisors decide. Every finding can be accepted, challenged or sent to the seller — and the report reflects the advisor's judgement.
Security

Built for confidential deals.

Bidder-grade access control
Per-folder and per-team access, view-only or download, time-limited access and one-click revocation. Buyers only ever see what you grant.
Dynamic watermarking
Every PDF is stamped with the viewer's name, email, company and date at the moment it is opened.
Full audit trail
Who opened, viewed or downloaded what, and when — per document, per bidder.
Verified entry
Invitations expire, require NDA acceptance and a one-time code sent to the invitee's email.
EU data residency
Documents and data are stored and processed in the EU. AI analysis never trains models on your data.
Isolation by design
Database-level row security separates every deal and every bidder, and is tested automatically every week.
Sell-side advisors
Run more mandates with the same team. Deliver a vendor DD pack and a clean, well-governed room from day one.
Founders & owners
Know what a buyer will find before they find it — and fix it, explain it or price it in.
PE portfolio exits
A repeatable, auditable exit-readiness process across portfolio companies.
