Mercor

Re-verified the highest-risk claims against primary/third-party sources. Funding stack confirmed: Series C $350M at $10B valuation (Oct 2025), led by Felicis (which also led the $100M Series B at $2B), with Benchmark, General Catalyst, and new investor Robinhood Ventures, corroborated by TechCrunch and CNBC. Total ~$492M (Tracxn) is corroborated by the per-round press breakdown, kept at 'reported'. Founded 2023; SF HQ (181 Fremont) confirmed. The Sepal AI acquisition (Feb 6, 2026, RL environments + training data for frontier labs) is confirmed and supports the directory note 'expert marketplace, environments emerging', this is the correct company. MAIN CORRECTION: headcount_band downgraded from 200+ to 51-200, matching the LinkedIn public snippet; the ~300 and 3,000+ figures conflate Mercor's ~30,000 contractor network with its lean full-time staff (Contrary Research notes ~30-50 FT employees through early 2025). Customers OpenAI/Anthropic/Meta are independently named by TechCrunch and Google DeepMind by theaiinsider, so 'verified' frontier-lab ties are retained but re-sourced to third-party press. SOC2 left 'unknown', the trust center shows no extractable certification, and press reports that Mercor's compliance vendor (Delve) allegedly issued fraudulent SOC 2 reports, so any certification claim is not credibly verifiable. focus_areas all conform to the controlled vocabulary.
