Find engineers and founders in Index Ventures’s portfolio

Index Ventures’s portfolio is a curated bet on the next wave of category-defining companies. The list above ranks Index Ventures-backed companies by current headcount, drawn from public LinkedIn and Crunchbase records. With 554 matching companies in Refolk’s index, the depth of senior engineers, founders, and operators is significant.
