Our mission: make every AI action provable.

AI agents will soon take more actions in a day than most teams can review in a year. Organizations deserve a way to prove what those agents did, and the confidence to let them do more.

Principles

What we will not compromise on.

Evidence over assurances

We would rather show you a record you can verify than ask you to trust a dashboard. That applies to our own claims too.

Customer-held keys

The party accountable to regulators and customers should control the seal. Our design keeps keys in your hands.

Open verification

Anyone should be able to check evidence offline, for free, years from now, whether or not they still work with us.

Honest limits

We publish what our technology proves and what it does not, and where the product stands today.

How we work

Built with design partners.

Attestorian is at the design-partner stage. We work closely with a small number of organizations through controlled pilots, measuring real performance and integration effort together before scaling.
