About
We build the only compliance tool that doesn’t need to be trusted.
Probatum exists because the compliance industry sells trust as a subscription, and that broke the moment the data we’re asked to govern got too sensitive to ship.
We started Probatum in early 2025 after watching enterprise deals stall on the same question: “Where will our evidence live?” The honest answer from the cloud-SaaS vendors we evaluated — “in our cloud” — wasn’t survivable for healthcare, defense, finance, or anyone touching EU AI Act high-risk systems.
So we built the harder thing. A desktop tool with a bundled local LLM. A SHA-256 hash-chained audit log. Ed25519-signed W3C Verifiable Credentials. An open-source verifier your auditor can run without us. Public pricing.
We picked the model that’s harder to monetize because it’s the one we want to use ourselves.
Our principles
Math beats marketing.
Every claim should be independently verifiable. If it isn't, it's a sales pitch.
Data stays.
If proving you handle data well requires moving it, the proof is broken.
Pricing is public.
A demo gate is a friction tax on small teams. We charge for the product, not the discovery call.
Verifiers belong to the customer.
The tools that check our work are open source. Bankrupt us — your VCs still verify.
Try it. Verify it. Then decide.
