London's Air Street Capital closes $232M Fund III, making it one of Europe's largest solo VC funds focused on early-stage AI.
Air Street Capital, led by Nathan Benaich, announced a $232 million Fund III targeting early-stage AI companies in Europe and North America. Check sizes range from $500K to $15M, with growth investments up to $25M. The raise brings Air Street's total AUM to $400M — nearly doubling from Fund II's $121M. The firm's portfolio includes AI unicorns Black Forest Labs and ElevenLabs, with exits from Adept (acquired by Amazon) and Graphcore (acquired by SoftBank).
This is a capital allocation story, not a technical one. No new APIs, models, or tooling changes. If you're a developer at an AI startup seeking seed or Series A in Europe or North America, Air Street is now the best-capitalized AI-specialist solo GP on the continent.
