Every decision,
kept.

A Decision Record is the call itself, kept as a durable object: the question, the options you did not pick, the evidence, the sign-offs, and the result. Typed, content-addressed, sealed when saved. The one thing every other tool helps you make, and none of them keeps.

New here? What is a decision system of record

An enterprise keeps everything except the decision.

Every invoice, every contract, every employee record is filed in a system built to keep it. The decision those things were gathered to make is the one thing that is not. It happens in a meeting, a thread, and a slide, and then it is gone: not the question as it was framed, not the options that lost, not the reason they lost. AI made that sharper, not better. A model generates a recommendation in seconds, so the recommendation is cheap. What is scarce is the kept, accountable record of the call.

Every part of a Record is kept for a reason.

The question, the options including the ones not picked, the evidence, the sign-offs, the result, and how sure the call was. Select any part to read why it is there.

Every part of a Decision Record, and why it is kept. Select a row to read it.

It keeps the options you didn't choose.

A dashboard keeps the answer. A chat keeps the transcript until you close the tab. Neither keeps the option you rejected, the reason you rejected it, or the dissent that turns out, a year later, to have been right. Switch the view and watch what survives.

A dashboard or a chat keeps the answer. The decision behind it is gone.
Same call, two ways of keeping it. Only one keeps the decision.

Sealed when saved, reconstructable for years.

The moment a call is signed, the Record is sealed and content-addressed: its identity is its contents, so what you open is provably what was saved. A correction does not edit it. A correction is a new record that supersedes it, so the history of a decision is append-only and never quietly rewritten.

We are deliberate about what sealed means, because a system of record that overclaims is worse than none. Today it means three things you can check: the Record is complete, it is content-addressed, and it is self-describing. Full tamper-evidence against a determined insider needs more: an external trust anchor outside your own tenant, and deterministic replay from pinned inputs. We are building toward both, and we will claim them when they hold, not before.

01

Capture

The question, the options including the rejected, the evidence, the sign-offs, the result, the confidence.

Draft
02

Seal

Sealed when saved. Content-addressed and self-describing. It is not edited; it is superseded.

Sealed
03

Reconstruct

Pull it up months later and read the decision as it stood, under the information available then.

Reconstructable

When finance, audit, a board, or a regulator asks why a call was made, you open the Record and read the decision as it stood: the question as framed, the options as weighed, the evidence as it was then, the people who signed. This is reconstruction, not recollection. You are not asking someone to remember it. You are reading it.
