Air Street becomes one of the largest solo VCs in Europe with $232M fund

London's Air Street Capital has solidified its position as a major force in AI venture capital with the close of its $232 million Fund III. Led by solo general partner Nathan Benaich, this raise triples the size of its previous $121 million Fund II and catapults the firm into the ranks of Europe's largest solo VC funds. The new capital brings Air Street's total assets under management to $400 million, a massive leap from its $17 million Fund I raised in 2020. The firm will deploy checks ranging from $500,000 to $15 million into early-stage AI startups, with the capacity for select growth investments reaching up to $25 million, targeting companies on both sides of the Atlantic.

Air Street Capital is not a new player but a proven one, with a portfolio that includes generative AI powerhouses like ElevenLabs and image-generation specialist Black Forest Labs. The firm has also secured notable exits, including the sale of AI agent company Adept to Amazon and chipmaker Graphcore to SoftBank. This track record provides significant validation for its thesis and execution. The fund's focus remains squarely on foundational AI technology, from infrastructure and developer tools to frontier research and enterprise applications, betting on the next wave of companies that will build the core components of the AI stack.
