Your calls have no proof of identity.
Anyone can spoof caller ID. Voice deepfakes clone identity in seconds. Every incoming call is cryptographically anonymous — until now.
Get Early AccessPair. Call. Trust.
Meet in person or exchange keys through another authenticated channel. Your devices generate cryptographic keypairs. No central server. No registration.
Every call includes a cryptographic signature. Your phone verifies the caller's identity in real-time using their public key. Anonymous calls show as unverified.
You decide who gets verified status. Block spam entirely or accept calls only from attested contacts. No servers hold your keys. Ever.
STIR/SHAKEN verifies numbers. Not people.
Carrier-level attestation confirms the originating phone number is legitimate — but it can't verify the person holding the phone. Anyone with access to an authenticated device can impersonate its owner.

Carrier signs the call

We're not launching to everyone.
We're looking for people who feel this problem — executives who've been impersonated, journalists who verify sources, lawyers who need call authentication.
