Background

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.

How the World Sees Them

Public markets

The planned $7.4bn acquisition of Janus Henderson repositions General Catalyst as a hybrid public-private manager, a model most traditional VCs have avoided.

European founders

With $8bn raised in 2024 and 25% earmarked for Europe, General Catalyst is competing directly with Atomico and Index for the continent's growth rounds. Its La Famiglia acquisition gives it an early-stage feeder.

UK tech ecosystem

General Catalyst is one of the few US mega-funds with a permanent London presence. Its repeated backing of PhysicsX signals appetite for deep-tech UK scale-ups, though the upside accrues to a foreign cap table.
