Why we built DataAnnotation
Our mission is simple: connect the world's most capable minds with meaningful AI work. We don't believe in assembly-line labeling. We believe in thoughtful, domain-expert review that teaches models to reason, not just classify.
Every annotation on our platform is a human decision — made by someone who understands the subject deeply enough to explain not just the "what," but the "why."
Trusted by industry leaders
Expert annotations powering the world’s most advanced AI systems.
What we stand for
People first
Every decision starts with the people who do the work. We design for contributor wellbeing, not just throughput. Fair pay, clear guidelines, and genuine respect.
Quality matters
We don't cut corners. Every annotation is reviewed, every edge case is documented, and every contributor is empowered to flag problems without friction.
Serious about safety
AI safety isn't a marketing line — it's embedded in our annotation standards. We train contributors to identify and surface harmful outputs, not just ignore them.
