Investment thesis
Index Ventures invests from seed to IPO in technology companies, working from San Francisco, New York and London and reaching founders from the West Coast to Tel Aviv. Its portfolio spans software and SaaS, fintech, artificial intelligence, gaming, cloud security and healthcare, including Figma, Revolut, Datadog, Roblox and Wiz. Thirty years in, the firm still frames selection around the people behind a company rather than the idea alone.
