Index Ventures portfolio companies in London

Index Ventures’s London portfolio is one of the most active recruiting pools in the market. The list above ranks Index Ventures-backed companies headquartered in London by current headcount, drawn from public LinkedIn and Crunchbase records. With 92 matching companies in Refolk’s index, you can see exactly where the Index Ventures thesis has landed locally.

Index Ventures companies in London tend to attract a specific type of operator - a founder or early hire bought into both the firm’s thesis and the city’s ecosystem. That makes the engineers and designers at these companies particularly valuable signals.

Refolk lets you reach this pool. Ask for “Index Ventures companies in London hiring founding engineers” or “founders of Index Ventures-backed companies in London who left in the last year” and Refolk returns a ranked shortlist with evidence behind each match.

How this list is built

Refolk pulled companies whose disclosed Crunchbase investor list includes Index Ventures and whose HQ is in London, ranked them by current employee count, and kept those with at least 5 employees. The list refreshes once a day.
