The read

Anthropic absorbed +400 net headcount over 90 days, overwhelmingly into engineering (now 1,102 strong, 65% of the org). VP-level hires include a Head of Communications from Stripe and a GTM leader from Vercel, signaling go-to-market muscle-up alongside the technical build. Inbound talent skews heavily toward Meta (44 joins), Google (30), and AWS (16) — the usual Big Tech feeder pattern for frontier AI labs. Minimal attrition (33 departures, including a manager-level Member of Technical Staff) and modest promotion activity (16, notably a Chief Economist elevation) round out a quarter defined by aggressive scaling.
