Index Ventures

Activity from announced rounds

Activity in this selectionMay 31, 2026 · May 1, 2026

Index Ventures invests across technology sectors from seed through venture and growth, with teams in San Francisco, New York and London.

The firm publishes practical research for founders through Index Press. Its resources address three distinct scaling decisions: structuring employee stock options, building an organisation as headcount expands and entering the US market.

OptionPlan, TeamPlan and ExpansionPlan accompany the research with planning tools. These resources are particularly useful when fundraising is tied to hiring, opening a US operation or redesigning compensation as a company moves beyond its founding team.
