Scale AI: CEO History

Scale AI sits between the people who build AI models and the organizations that use them. For labs it provides the human-written examples, rankings and test sets used to train and grade models. For enterprises and governments it builds the applications that put those models to work. The company updated its mission in September 2025 to developing reliable AI systems for the world's most important decisions. The company is headquartered in San Francisco, California.

Scale AI earns money in two ways. Its data business charges AI labs and large technology companies for training data, reinforcement learning environments and model evaluations, produced by software pipelines plus a paid contributor network run through Outlier and Remotasks; the company says it has paid contributors more than $1 billion over ten years. Its applications business sells and deploys generative AI systems built on the Scale GenAI Platform and Donovan to enterprises and governments, typically through multi-year contracts. Scale does not publish revenue by segment. It said the data business became profitable in the second half of 2025 and that applications revenue more than doubled in that period.
