Principle 01
Your AI now acts in your name. Your reputation rides on what it does. We keep you in control of every move, and let anyone check the record.
We call it
Verifiable AI.
Start here
How would you answer these questions?
- Do you know what your AI is doing?
- Most teams can't say precisely. A log tells you a call happened. It doesn't tell you what the agent was allowed to do, who approved it, or whether your rule actually held.
- Do you understand what it's exposing you to?
- Every action your agent takes in your name is already your liability. It moves money, shares data, and makes promises on your behalf. When you can't prove what your AI is doing, your governance is just a document, and your reputation in the market is what pays.
What we do about it
You can prove every action your AI takes.
- 01
You see every move it makes.
You will never see inside the model, and you don't need to. What matters is what your AI actually does: sends the email, moves the money, shares the file, agrees to the terms. We record every one of those actions, who approved it, and which rule it followed.
- 02
Your rules decide before it acts.
You write the policy once. It runs the moment your AI tries to act, not in a review weeks later. Anything high-stakes waits for a person to say yes. If a rule can't be checked, the action stops instead of guessing.
- 03
Anyone can check the record.
Each action becomes a signed record. Your customer, your auditor, a regulator, or a court can check it themselves, without taking your word for it, or ours.
What we build
Stones AI's products work at the moment your AI acts, and nowhere else. We check every action against your rules, and turn each one into evidence you can stand behind.
Who we build for
For companies that can't afford to be wrong.
Teams shipping their first AI agent into production. Regulated companies who have to answer for what their models do. Firms where a single AI decision can move money, deny a claim, or land in front of a regulator.
If that's any of you, we're building for all of you. Your reputation now rides on what your AI does in your name, and on whether you can prove it. Verifiable AI is for anyone serious about standing behind it.
