Know someone whose team could beat Proof of Quality?

If you refer the team that wins, we’ll pay you $1,000.

We've been working through a practical question: how can a small expert team oversee quality at huge scale? Ten experts can't read 100 million training items. They can still decide what good looks like.

We use their answers to test AI judges before they review the larger set.

One question has shaped much of what we’ve built at Sapien: where can human judgment have the most impact on AI?

When we started, people were doing much of the work of creating and labeling data. After two years and 195 million tasks, we learned how difficult it is to measure quality reliably at scale.

As AI gets better at doing the work itself, the role of human expertise becomes even more important. People need to define what good means, decide which tradeoffs are acceptable, and retain responsibility for the decisions that deserve human judgment.

Where we think human judgment goes next, and why this question is central to Sapien’s long term direction:

A small update for our token holders: We’re simplifying how wallet exports work and winding down Sapien’s Privy integration, which means wallets.sapien.io is being retired. Privy provides the export flow directly at home.privy.io whenever you need it.

AI systems can generate thousands of outputs before a team has time to inspect a fraction of them. When outsourcing this to AI, one of the hardest parts is deciding how much confidence to place in a single judgment.

Proof of Quality supports multiple AI reviewers in a single workflow, so teams can compare scores, reasoning, agreement, and disagreement, giving them a faster way to test evaluation workflows at scale while keeping expert attention focused on ambiguity and high consequence cases.
