That information pertains to Alexandr Wang, the other co-founder of Scale AI alongside Lucy Guo.
The details you provided are accurate:
Net Worth: Forbes has estimated Alexandr Wang's net worth to be around $3.2 billion (or $3.6 billion in other recent estimates), which stems primarily from his stake in Scale AI.
Move to Meta: In June 2025, Alexandr Wang stepped down as CEO of Scale AI to join Meta Platforms (Facebook's parent company) as its new Chief AI Officer. This move was part of a major deal where Meta made a significant investment in Scale AI, which now values the company at around $29 billion.
