Vouch
Proof it's really them.
Digital trust
The premise
A convincing clone of a voice now takes seconds to make, and the fastest-growing fraud on earth is a phone call from someone you love who isn't real. Trust used to be the default. Vouch makes it provable.
Vouch is a thin authenticity layer that sits across calls, video, and money transfers. Before a synthetic voice or face can impersonate someone you trust, Vouch quietly confirms there is a real, present human on the other end — and flags it the instant there isn't.
How it works
Challenge
Live interactions are checked for the micro-signals of a real person — signals a deepfake can't reproduce in real time.
Attest
Verified humans and devices carry a cryptographic seal, so the people who matter to you are provably themselves.
Flag
Anything synthetic is caught before the transfer goes through, the deal is signed, or the panic sets in.
Signals
Be first when Vouch opens its doors.
Never shared, never sold. One reply removes it.
Vouch is an exploratory Invisally concept.
