Biographies

Alexandr Wang’s career connects two often separate stories about artificial intelligence: the human work that makes data useful, and the organisation of laboratories that build frontier models. Raised in Los Alamos by physicist parents, he showed an early aptitude for science before leaving MIT and co-founding Scale AI with Lucy Guo in 2016. Scale turned data preparation and evaluation into a major business. Meta’s 2025 minority investment then brought Wang into its own AI leadership. This profile follows that transition through his upbringing, the company’s formation, its defence-planning work and his responsibilities at Meta. It also examines what the headline transaction actually meant, why labelled data is important without being the sole basis of AI, and how the contribution of researchers and annotation workers fits into the story. A dated chronology, a biographical record and linked sources place the individual within the wider institutions that shaped his influence.
