General Catalyst followed on in PhysicsX's $300m Series c in June 2026, the UK's largest private AI round of the week, at a $2.4bn valuation, more than double the prior round. The firm had led PhysicsX's $32m Series A in November 2023, making this a third consecutive commitment to the London company across three years.
Founded in 2000 in Cambridge, Massachusetts, General Catalyst manages over $43bn in assets across seed, early-stage and growth equity. Its October 2024 raise closed $8bn across three vehicles, with roughly 25% allocated to Europe. The firm opened a London office in December 2021 and acquired the German early-stage fund La Famiglia in June 2024, appointing Jeannette zu Fürstenberg to lead European operations. It holds stakes in Monzo, Deliveroo and Multiverse, among 800-plus portfolio companies globally.
CEO Hemant Taneja has steered General Catalyst toward a hybrid model blending venture and public-market exposure: the firm announced an agreement to acquire asset manager Janus Henderson for $7.4bn in late 2025, a structural shift that places it among the few VC firms managing both private and public capital at scale.
