Meta finalized a $14.3B investment for a 49% stake, valuing Scale at approximately $29B; founder Alexandr Wang moved to Meta and Jason Droege became interim CEO. The transaction created customer-neutrality and confidentiality concerns because Meta competes with Scale customers.
SourceReports said Google halted multiple projects, OpenAI was winding down work, and xAI paused some projects after the Meta investment; this was reported customer pullback, not a confirmed company shutdown.
SourceScale reportedly cut approximately 200 full-time employees, about 14% of a roughly 1,400-person workforce, and ended contracts with about 500 contractors while restructuring its GenAI group.
SourceScale appointed Francis deSouza CEO effective August 10, 2026, after more than a year of interim leadership; the transition reflects a post-Meta effort to expand enterprise and government applications.
