Background

Index Ventures has been one of the most active investors in the UK and European funding surge of 2026. It led Granola's $125m Series C in March 2026, taking the London AI notetaking startup to a $1.5bn valuation, six times its level a year earlier. In May 2026 it participated in Multiverse's $70m Series E at a $2.1bn valuation, the round that confirmed Multiverse as the UK's leading AI upskilling platform and its first cash-positive quarter. Between those two deals it co-invested in Ineffable Intelligence's $1.1bn seed round on 27 April 2026, the largest seed in European history, alongside Sequoia, Lightspeed, and the British Business Bank.

Index was founded in Geneva in 1996 by Neil Rimer, David Rimer, and Giuseppe Zocco, evolving from Swiss bond-trading roots into a transatlantic VC. The firm opened its London office in 2002 and San Francisco in 2011, operating a one-fund, one-team model where the same partnership backs companies from seed through growth. In July 2024 it announced $2.3bn in new funds ($800m early-stage, $1.5bn growth), bringing total capital raised to approximately $15bn.

Index's portfolio defines European venture's highest-water marks: Adyen, Deliveroo, Farfetch, King, Supercell, Skype, Squarespace, Roblox, Discord, and Figma. Its dual London-San Francisco footprint positions it at the intersection of European tech sovereignty and transatlantic scale; its 2026 deal pace in UK AI (Granola, Ineffable, Multiverse) mirrors its earlier playbook of building concentrated positions in emerging UK software categories before US capital noticed them.

How the World Sees Them

US market

Its San Francisco presence gives European portfolio companies validated introductions and credibility for US market entry; the partnership's shared model means the same partners follow companies across both markets.

UK startups

Three major UK AI investments in under three months in 2026 (Granola, Ineffable, Multiverse) confirm Index as the most prolific top-tier VC in the current UK AI funding wave.

European VC ecosystem

Index's Geneva origins and London base make it the benchmark European VC: it competes directly with the best US firms, carries European regulatory credibility, and has delivered some of the continent's defining exits.
