Building the trust layer for AI
After 3 years in the trenches of AI data, we saw the same problem everywhere.
The AI industry has a quality problem it can't see.
Every team defines quality differently. Work happens inside tools that can't be audited.
No one can prove who created a piece of data or whether it should be trusted. And as AI systems become more autonomous, the stakes keep rising.
So we built PoQ:
the trust layer for AI.
Open infrastructure for verifiable quality signals.
Our Team
A multidisciplinary team of data, AI, and product experts
