Building trust for the
Agent Internet.

AI agents are transacting on behalf of humans. They need to know who they're dealing with. We build the infrastructure to answer that question.

Mission

Universal verification for anyone who needs to be found — businesses, journalists, researchers, artists. One open protocol. Cryptographic proof. Machine-readable trust.

What we believe

Principles behind the protocol

🔓
Open protocol
The verification protocol is MIT-licensed. Anyone can build on it, fork it, or run their own node. No vendor lock-in.
🔐
Cryptographic truth
Verification is anchored in registry data, C2PA content signing, and Bitcoin timestamps — not in our word alone.
🌍
Universal, not business-only
A journalist, an organic farm, a research institution — all deserve verified presence in the agent economy.
The company

TetaPi GmbH

Founded in 2026 in Frankfurt am Main, Germany. We are a small team focused on one problem: making identities verifiable for the age of autonomous AI agents.
TETA+PI is our first product — a public verification registry with an open MCP interface. We believe infrastructure for digital trust should be open, auditable, and available to everyone.
We're backed by early believers who share our conviction that the Agent Internet needs a trust layer — built right, from the start.
