## What it is

Index Ventures is a venture capital firm headquartered in London, with offices in San Francisco, New York, Geneva, and Jersey. Founded in 1996 in Geneva, Switzerland, it operates as a multi-stage generalist investor, writing cheques from seed through late growth across three parallel vehicles: a seed fund (Index Origin), a core venture fund, and a growth fund for late-stage follow-on positions. As of mid-2026, the firm has backed more than 660 companies across 32 funds, producing 65 active unicorns, 57 public-company exits, and 23 decacorns. A team of 68 people, including 33 partners, operates across all five offices.

## History

The firm's lineage traces to Index Securities, a Swiss bond-trading company founded by Gerald Rimer in 1976. Gerald recruited his son Neil Rimer to the firm in 1992. Neil Rimer, David Rimer, and Giuseppe Zocco formally launched Index Ventures in Geneva in 1996, at a time when most US funds considered European founders unable to build at scale.

Early marquee bets included Skype, the voice-over-internet service acquired by eBay in 2005 for US$2.6 billion, and Betfair, the UK online-betting exchange that listed on the London Stock Exchange in 2010. The firm moved its primary operating base to London around 2002 and opened a San Francisco office to capture US-expansion opportunities from European-founded companies.

The 2010s brought a run of public exits: Dropbox (Nasdaq IPO, 2018), Etsy (Nasdaq IPO, 2015), Adyen (Euronext Amsterdam IPO, 2018, the Dutch payments company), and Spotify (New York Stock Exchange direct listing, 2018). Slack joined the portfolio ahead of its 2019 direct listing. Figma, the design-collaboration tool, became one of the decade's highest-profile near-exits when Adobe's planned US$20 billion acquisition was blocked by UK and EU regulators in late 2023. Revolut, the UK digital bank, has been an active portfolio holding since 2015 and reached a secondary-market valuation of US$45 billion by mid-2024.

## Current state

In July 2024, Index Ventures closed Index Ventures XII, a US$800 million early-stage fund, and Index Growth VII, a US$1.5 billion late-stage vehicle, totalling US$2.3 billion. Combined with the existing US$300 million Origin II seed fund, the firm is deploying US$2.6 billion from those vehicles. More than half of recent deployment has targeted AI companies, including [Anthropic](/ar/n/anthropic-dossier), the US AI safety lab, Scale AI, and Mistral, the French foundation-model startup. The firm co-invested in [Alan's June 2026 Series G of €480 million](/ar/n/alan-series-g-2026) alongside Prosus and Teachers' Venture Growth, the largest European healthtech round of the year. The 2025 exit vintage returned an estimated US$9 billion, including realized gains from Wiz, ClickHouse, and post-IPO Datadog positions.

## Relationships

Index Ventures competes and co-invests with [Sequoia Capital](/ar/n/sequoia-dossier) and [Andreessen Horowitz](/ar/n/a16z-dossier) across AI infrastructure and foundation-model rounds. The firm's European founding gives it familiarity with EU and UK regulatory processes that US-only funds lack, illustrated by its long cap-table presence on Revolut and BlaBlaCar, the French intercity ridesharing company. Its early position in Mistral, Europe's most valuable AI startup, places Index as the leading transatlantic bridge for French-origin AI companies scaling into the US enterprise market. Investment in Anthropic alongside Accel, Google, and Spark Capital deepens the firm's exposure to the US AI safety sector.

## What to watch

Deploying Index Ventures XII and Growth VII into an AI market with compressed early-stage valuations and a selectively open IPO window is the firm's defining near-term challenge. Revolut, held since 2015, is among the largest unrealized private fintech positions globally; its anticipated London Stock Exchange IPO, expected in 2026 or 2027, would be one of the decade's most consequential European tech listings and a significant driver of fund returns. Whether the European AI cohort, led by Mistral, can generate US-comparable exit multiples will determine how much of the European VC premium Index can sustain in future capital raises, and whether its dual-continent positioning hardened into a structural advantage or remained a geographic hedge.
