Scale AI

What Scale AI does

Scale AI cleans, labels and creates data that AI developers use to train and evaluate models. It began with labeling text, images and other unstructured data and has moved toward more skilled work, such as writing complex problems for reinforcement learning. Bloomberg reported that about 12% of its contractors hold a PhD and about 40% hold a master's, law degree or MBA (SiliconANGLE).

Its customers have included Meta, Microsoft and OpenAI, and it has worked with the US government on defense AI, including Defense Llama, a version of Meta's Llama built for military use (SiliconANGLE).

The Meta investment

In June 2025 Meta agreed a multibillion-dollar investment in Scale AI, and Alexandr Wang left to join Meta (SiliconANGLE). If you compete with Meta, ask any vendor how it separates work for different customers.

How it compares with a data broker

Scale AI produces data with its own workforce. It is the right kind of supplier when you need people to label or write data to a specification. It is not usually where a company goes to license an archive it already holds. If you hold real-world data, such as support tickets, code history or recordings, a broker or marketplace is the more direct route. See how to sell data to AI companies.

Things to check before you sign

• Who owns the labeled output, and can the vendor reuse your guidelines or data for other clients?
• Where the workforce is located, and how your data is protected while people work on it.
• How quality is measured: agreement rates, audit samples and rework terms.
• Whether the vendor also works for your direct competitors, and what separation it offers.
