The firm, based in London and San Francisco, has had a successful year so far, following the exits of Adyen, Dropbox, iZettle and Zuora.
Commenting on the news, Kathryn Mayne, a managing director at Horsley Bridge Partners, which has backed every single Index Ventures fund since 2005, told the New York Times: “When you find a venture fund that we will back in successive iterations, it tends to be because they’ve figured out that formula or magic where they’re investing early in transformative companies.”
The funding will be split across two funds: $1bn will be allocated to growth-stage investments and $650m will be put aside for the firm’s ninth venture fund, which targets early-stage businesses.
Founded in 1996 in Switzerland, Index Ventures has raised a total of $7.65bn to date. The fund previously raised $1.25bn in 2016.
