Meta cuts VirtueAI hires 4 months on, citing 'clashing work styles' with Song's team

The VirtueAI team founded by UC Berkeley professor Dawn Song joined Meta's Superintelligence Labs in June, but Meta is now cutting many of them after just four months, citing "clashing work styles." Details of the disagreement weren't disclosed, and it's unclear whether Song and co-founders Bo Li and Sanmi Koyejo have all left.

VirtueAI specialized in red-teaming AI systems, finding vulnerabilities, and runtime guardrails — capabilities Meta wanted as it pushes AI agents and superintelligence. The piece cites MIT Sloan research showing acquired employees leave at 33% in year one vs 12% for regular hires, pointing to organizational mismatch as the likely root cause.
