About Epheia
Every AI company promises privacy. The promises live in policies: terms of service, data processing agreements, statements like "we do not train on your data." None of that is proof. It is the company describing its own behavior, which nobody outside the company can confirm.
The problem it solves
For people who handle sensitive information, such as lawyers, doctors and financial advisors, "trust us" is not an acceptable answer. The result is backwards: the professions that could benefit most from AI are the least able to use it.
And it does not stop at professionals. Everyone has questions they hesitate to type into an AI that remembers: about their health, their money, their relationships, their fears. The more sensitive the question, the less served the person asking it. Epheia replaces the promise with evidence, for everyone.
Founder's note
Epheia started with an ordinary moment. I was using an AI assistant for something personal, and it struck me that I had just handed a private matter to a company with no way to learn what happened to it next. Not what the policy said. What actually happened. Nobody can find that out, and closing that gap is the whole company.
I designed the receipt format and the verification protocol, and built the parts that carry the trust: the sealed appliance, the erasure mechanism, and the verifier you can run yourself. I wanted to be able to explain every step of it myself.
I am also training toward psychiatry, the specialty where concealment costs patients the most. That is why healthcare is the first vertical rather than a later one.
A familiar way to picture it
The fastest way to understand what Epheia is building is through companies you already know.
Stripe for private AI
Stripe turned accepting payments into infrastructure any business can plug in, without becoming a payments expert. Epheia does that for provable privacy.
DocuSign for AI privacy
DocuSign turned signatures into digital artifacts courts accept as evidence. The receipt is an artifact auditors and regulators can accept as evidence of how AI was used.
The padlock for AI
The padlock made website encryption something everyone expects, checked automatically. Epheia aims to make the privacy receipt something every AI user simply expects to receive.
The padlock is the operative analogy: encryption became universal because relying on it was free. The receipt spreads the same way.
For investors and partners
Every AI provider promises non-retention. None can prove non-persistence. Epheia closes that gap, backed by a patent-pending portfolio covering the core protocol and an open specification. The receipt format is vendor-neutral by design, because a proof that only works when Epheia is in the path is not a proof anyone should accept.
