We're building the talent layer for frontier AI.

ScalableAnnotationswas founded on a simple bet: as models get smarter, the bottleneck is no longer compute or architecture. It's the quality of the human judgment used to teach them.

We exist to make that judgment scalable. We recruit, vet, and calibrate domain experts across science, math, code, medicine, law, and language. We then put them inside the workflows of the labs building the most ambitious AI systems on Earth.
