Index Ventures

Index Ventures is a global venture capital firm that invests in technology-driven startups across stages from seed to growth, with a core philosophy of building long-term partnerships with founders.

Their core sectors include artificial intelligence (AI), enterprise software/SaaS, fintech, healthcare, e-commerce, security and platform/open-source technologies.

Index Ventures invests across the full lifecycle from seed (including pre-seed) to growth and IPO stages, and operates a dedicated seed fund called Index Origin.

It is generally recommended to approach them through a warm introduction. The team has offices in major technology hubs including London, San Francisco and New York.

Index Ventures is an active investor in AI and has backed companies like Scale AI and Cohere. They view AI as driving a platform shift comparable to cloud, and pay attention to the value distribution between base models and application-layer companies.

They provide support such as transatlantic market expansion assistance, recruiting guidance based on an extensive talent network, policy advocacy, and long-term strategic partnership and resource introductions.

Representative investments include well-known tech companies such as Figma, Robinhood, Revolut, Roblox, Slack, Adyen, Datadog, Wiz and Scale AI.

Their core philosophy emphasizes investing in the founder themselves—focusing on personal traits, mission and execution capability—and building long-term partnerships grounded in strong conviction rather than one-off transactions.
