Where our experts make the difference
RLHF & human feedback
Feedback that actually makes your model better.
Domain experts provide the nuanced signal that generalist crowds can't — rated, ranked, and explained in context.
Evaluation & QA
Test against real-world expectations, not benchmarks.
Domain-matched experts evaluate outputs across languages and edge cases your team would never think to test.
Red teaming
Find the failures before your users do.
Adversarial testing by people who know your industry — they probe where your model is most likely to fail in production.

Better inputs make better models.
Representative domain experts who understand your industry produce more accurate outputs, so your AI works for more of the people it's built to serve.
More accurate outputs
Experts who understand your use case catch errors that generic annotators miss.
Defensible by design
Verified identities and credentials mean you can explain who trained your model to your regulators, your legal team, and your board.
Fewer blind spots
A representative expert pool catches edge cases a homogenous team won't see before they hit production.
Consistent across releases
Work with the same experts across model versions. Familiarity with your data compounds over time.
