100-word summary
Air Street Capital just closed a $232 million fund, making it Europe's largest solo general partner venture operation. That's one person, Nathan Benaich, now controlling $400 million in total assets without the usual partner committee. The fund will write checks from $500,000 to $25 million for AI-first companies in North America and Europe, targeting everything from developer tools to defense tech. Portfolio companies include Synthesia and Black Forest Labs, with exits like Adept to Amazon already on the books. The bet: having a single decision-maker beats consensus-building when AI moves this fast. US university endowments and hospitals are increasingly backing the model, suggesting institutions think speed trumps oversight.
