Ethos raises $22.75M Series A from a16z for AI-powered expert-network hiring

London-based AI recruitment startup Ethos has raised a $22.75 million Series A round led by Andreessen Horowitz (a16z), with participation from General Catalyst. The company uses AI voice agents to conduct dynamic interviews, probing candidates beyond resume keywords to build granular skill profiles for enterprise clients including top hedge funds and AI labs. Ethos adds roughly 35,000 professionals weekly and is approaching $10 million in annualized revenue.

Why it matters: Ethos exemplifies the recurring pattern of AI agent–driven vertical marketplaces, where the value comes from active intelligence gathering rather than passive resume matching. The round also fits the broader capital cycle dynamic in London's AI talent infrastructure space, though the $22.75M sum keeps it in the conventional Series A range rather than triggering a cross-substrate capital signal. The founding team — a former McKinsey/SoftBank executive paired with a DeepMind veteran — mirrors the cross-substrate talent pattern of top-researcher founders applying technical AI to traditional B2B verticals.

Grounded expert take: This is a modestly significant update to the AI recruitment segment (Segment 08). The company is not yet a canonical case-study player, but its traction with hedge funds and AI labs — a demographic notoriously demanding of candidate depth — suggests its skill-profiling approach has genuine product-market fit. The real test will be whether Ethos can extend beyond finance and AI-native clients into mainstream enterprise hiring, where procurement inertia and incumbent HR platforms create strong distribution moats.
