Pricing
Flat plans, published here, from free to unlimited. No per-page fees, no storage surcharges, no quote roulette. AI with cited answers and the hash-chained audit log are in every tier, never sold as an add-on.
Plans
Monthly prices shown. Every plan includes AI with cited answers, the hash-chained audit log, and Claude/ChatGPT agent access.
Flat-rate plans. No per-page fees, no per-user fees on the room tiers, no usage surprises.
Every new account starts with a 14-day Data Rooms trial, no credit card required. When it ends, the account moves to the Free plan unless you upgrade; paid features such as watermarking, NDA gating, permission groups and Q&A need a paid plan.
Data Room Cost
Competitor pricing details are based on publicly available information as of mid-2026. The model matters more than the sticker: it decides whether thorough diligence costs you extra.
| Model | How it bills | What it does to your invoice |
|---|---|---|
| Per-page billing | You pay for every page uploaded, at a rate set in your contract rather than published | ✗ The total is unknowable until the deal closes, because the rate is contractual, not published |
| Per-user billing | You pay for every named user or seat | ✗ Costs climb as diligence widens; teams ration who gets access |
| Storage tiers | You pay by gigabytes stored, quoted after a sales call | ~ Price is unpredictable until the call, and grows with the room |
| Flat plans (Sifrsys) | One published monthly price per tier | ✓ Upload everything. The invoice is the same number every month |

A mid-market M&A process can run to tens of thousands of pages, and under per-page billing nobody can tell you the total until it is over. We checked ten providers on 4 August 2026 and none publishes a per-page rate. Intralinks names pages as a billable unit in its published billing terms and leaves the rate to a per-customer Work Order, which is the pattern across the category: the unit is disclosed, the number is not. Six months on Sifrsys Data Rooms costs $894, and you could work that out before uploading the first document. Per-page pricing also taxes thoroughness, because the more complete your data room, the more you owe. We think that incentive points the wrong way, so our plans are flat.
Included in Every Plan
These come with every plan, including the free one. Where a paid feature starts is listed on its plan above.
Ask questions in plain language. Every answer cites the exact page in the PDF or the exact cell range in the spreadsheet, so you verify instead of trusting.
The AI only retrieves from documents each participant is allowed to see, enforced at the database level with Row-Level Security, not by app-layer filtering.
Send a document by link with a password or an expiry date, and see page by page what each visitor read.
Connect Claude or ChatGPT through MCP or the API on every plan, within that plan's limits and monthly AI-question allowance.
Every document access is recorded in a hash-chained audit trail, on every plan including the free one. Owners and admins can export it, which is the record buyers and counsel ask for.
The price on this page is the price. No per-page fees, no surprise line items, and a 14-day Data Rooms trial with no credit card.
Price-Lock Guarantee
Deals run long. Your data room bill should not drift while they do.
Sifrsys commits to no surprise mid-contract increases and 90 days notice for any pricing change. Reviewers of some legacy providers, based on publicly available information, report notable increases arriving at renewal. We put the opposite in writing. Sifrsys is also independent: not a subsidiary of Datasite, unlike Firmex and Ansarada, based on publicly available information. And rather than asking you to take security on faith, the Trust Center lists exactly what we do and do not claim, verified against what is actually shipped.
The Founding 10
The first ten paying companies on Sifrsys get more than a discount. They get three commitments, in writing.
The price you sign at is your price for as long as you stay subscribed. Not for a year. Not until renewal. For the life of the subscription.
We move your documents, folder structure, and permission setup out of your current data room ourselves, at no charge. You review the result instead of doing the work.
You get the founder's direct line, not a ticket queue. Answers the same business day, and a real say in what gets built next.
Why offer this? Because the first ten companies shape what gets built next, and they should be looked after accordingly. Ten companies. When the spots are gone, this section comes down.
