Index Ventures raises $2 billion: three funds, three ages

The fact

On 31 July 2026, the investment firm Index Ventures said it had raised $2 billion from its backers. The money did not go into one pot. It was split across three separate vehicles: $400 million for seed, $900 million for venture, and $700 million added to a growth fund that now stands at $2.2 billion. Total firepower: $3.5 billion.

Why it matters

The split is not an accounting detail. It is the life cycle of a company, translated into dollars. A seed fund writes cheques of a few hundred thousand dollars to dozens of companies that often have nothing more than a prototype. A growth fund writes cheques of tens of millions to a handful of businesses that are already established. The smallest pot will back the largest number of projects: that is the venture funnel, and it is why the three compartments cannot be mixed. An investor who accepts losing the stake nine times out of ten is not signing the same contract as one chasing steady returns.

The second lesson is about fuel. That $2 billion comes from pension funds, university endowments and family offices whose appetite is fed by recent exits and secondary sales in the portfolio: Alphabet’s $32 billion purchase of the cybersecurity firm Wiz, in which Index held a 12 percent stake, or Revolut reaching a $115 billion valuation through a sale of existing shares. An exit is therefore never an end point. It is the moment capital drops back down one rung of the funnel to fund the next generation. The harsher corollary: when exits dry up, fundraising slows too, one or two years later.
