Index Ventures was founded in Geneva in 1996 by Neil Rimer, David Rimer and Giuseppe Zocco, evolving from Swiss bond-trading roots into a transatlantic venture firm with offices in London, opened in 2002, and San Francisco, opened in 2011. It invests across every stage, from seed through growth, and shares partners across its European and American offices so portfolio companies keep the same TEAM on both sides of The Atlantic.
The Firm's historical portfolio defines several of European venture's highest-water marks, including Adyen, Deliveroo, Farfetch, King, Supercell, Skype, Squarespace, Roblox, Discord and Figma. As of July 2024 it had raised roughly $15bn since founding across its full fund history, a separate figure from any capital raised since.
Index's London office, opened in 2002, gives it an early look at British companies before purely US-focused firms arrive. That pattern stretches from historical exits such as Skype and Squarespace through to its co-led role in Granola's Series C (with Kleiner Perkins) and Wordsmith AI's Series B (with Highland Europe) in 2026, and its participation, alongside Google, Nvidia and the British Business Bank, in Ineffable Intelligence's $1.1bn seed round the same year, co-led by Sequoia Capital and Lightspeed Venture Partners.
Index keeps writing UK AI cheques
Index co-led Edinburgh legal-AI firm Wordsmith AI's £52.1m Series B alongside Highland Europe on 4 June 2026. It followed Index's co-led role, alongside Kleiner Perkins, in Granola's $125m Series C in March, valuing the London notetaking platform at $1.5bn, and its participation, alongside Google, Nvidia and the British Business Bank, in Ineffable Intelligence's $1.1bn seed round on 27 April, co-led by Sequoia Capital and Lightspeed Venture Partners.
That pace reflects fresh Firepower: on 31 July 2026 Index raised $2bn across three new funds, taking its total investing capacity to $3.5bn across every stage from first cheques to growth rounds. As UK venture funding concentrates into a handful of AI megadeals, that capacity keeps Index able to write cheques at the scale those deals now require.
