When Alexander Wang founded Scale AI in 2016, the AI landscape was still in its early stages. The data labelling startup, driven by Wang’s vision, quickly became a key player in the AI landscape, growing to over 1,500 employees and securing crucial partnerships across industries and governments.

Wang will remain involved with Scale AI as a board member and is expected to bring several employees with him to Meta. He has led the company since co-founding it in 2016 to supply high-quality labeled data—sourced through human contractors—for training A.I. systems.

Data-labeling firm Scale AI confirmed on Friday that it has received a "significant" investment from Meta that values the startup at $29 billion.
