Mercor is negotiating a $20B round (2x its Series C) just months after a supply chain breach lost Meta, while acquiring AI training environment startup Deeptune to own the full agent stack.

If the round closes as expected later this month, the startup’s three 23-year-old cofounders would be worth an estimated $4.3 billion apiece.

The acquisition comes as Mercor says it reached $2 billion in annual recurring revenue despite a high-profile cybersecurity breach in March.
