Scale AI
FeaturedThe AI-ready data platform.
Founded in 2016 by Alexandr Wang and Lucy Guo while still teenagers, Scale AI was built on the insight that the biggest bottleneck to AI development is not algorithms — it is high-quality labeled training data. Scale provides data annotation, RLHF pipelines, model evaluation, and AI application development services to virtually every major AI lab and government in the world, including OpenAI, Meta, Microsoft, and the US Department of Defense. In 2024, Scale raised $1 billion at a $13.8 billion valuation. It is often described as the picks-and-shovels company of the AI gold rush.
