What a room is.
A room is one deal. It holds the documents for that deal, the blind teaser, the agreement version your readers accept, every reader you invite, and the evidence chain for all of it. It stays open until you close it, and closing it ends the access without ending the terms your readers agreed to.
Everything in the list beside this is in every tier, including the cheapest one. We do not put the watermark, the evidence chain or the honest limits behind an upgrade: they are what the product is, and a version of SIDR without them would not be worth selling.
In every room, in every tier
- Server-side rendering: the original file never reaches a reader’s browser
- A visible per-copy mark on every page a reader opens
- Staged disclosure, L0 to L2 or higher by tier, enforced on the server
- Registration and three independent time anchors
- Append-only, hash-chained evidence and the offline verifier
- Revocation, measured at 115 ms against a 5-second budget
- Your readers keep their own agreements, at no cost to them, forever
Readers are never charged and never need a subscription. The person you invite pays nothing to read.
What we do not charge for.
Uploading a 400-page memorandum costs the same as uploading a 4-page teaser. Per-page pricing makes you ration what you disclose, which is the opposite of what this product is for.
Invite the whole buy-side. A plan includes up to 1, 3 or 8 seats for your own team. Readers are never seats and never billed.
Readers return as often as they like. Metering attention would give us a reason to want more of it, and we do not want a reason.
We take no percentage of your deal, hold no funds, and have no interest in the outcome. Deal proceeds never pass through SIDR.
Questions we would ask.
What happens when I close a room?
Your readers lose access within seconds and see a page telling them what happened and who to contact. Their copy of the agreement they accepted stays with them, because it is their contract. Your evidence certificate for that deal is yours to export and keep, and it verifies without us. Closing a room frees the active-deal slot it held; it does not cancel your plan. Cancel any time from Settings, your record stays yours and exportable.
Can I export the record if I stop paying?
Yes. An evidence package is a file, and it verifies with open tools on your own machine. That is the point of building it that way: an evidence product you can be locked out of is not evidence.
Do my readers pay anything?
No, and they never will. They create one identity that works for every originator who invites them afterwards.
Is there a free tier?
Yes. Registering a deal, its blind teaser and its timestamp are permanently free, with no card. Inviting a real reader to a level above the teaser needs an active plan.
What does it cost elsewhere?
The established data rooms charge per page or per user, and a large process can run into five figures before anyone has signed anything. We are not going to pretend to know your alternative’s quote. We will say that one flat monthly plan, sized to how many deals you have open, is what we would want if we were paying, which is why it is the one we built.
Why not just sign an NDA and a non-circumvention?
The agreement is the right and SIDR does not replace it. SIDR is the same agreement accepted at the deal’s door and tied to evidence: which reader opened which page at which level and when, every copy carrying that reader’s name and code, and every acceptance recorded with its version, its content hash and its time, verifiable with the bundled verifier SIDR never has to be trusted to run. SIDR does not stop a camera; it names the photo.
Show it. Own it.
Set up a room and see what your counterparty sees before you decide anything. If you would rather talk through a live process and what it would cost, that door is open too.
