Sapien is a decentralized data foundry connecting enterprises building specialized AI models with a global network of humans who source, structure, and verify high-quality training data.

At the core is Proof of Quality, a system designed to answer two key questions every AI builder faces: Who created this data, and can it be trusted? It uses onchain incentives, staking, and reputation to align contributors and enforce quality automatically.

Sapien powers data pipelines for companies like Amazon Zoox, the United Nations, Toyota, Lenovo, and Alibaba, supporting everything from autonomous driving and robotics to large language model evaluation and safety research.

We’re building reliable infrastructure for human intelligence — an open protocol that lets anyone contribute to AI development and prove the quality of their work.
