About
Index Ventures' home page says it invests in who you are, not just what you do, and that it is invested in the people behind great ideas. The contact page lists offices in San Francisco, London, New York, Geneva, and Jersey, and it gives London as the registered office of Index Ventures (UK) LLP. It does not label one office as the headquarters. Street addresses, phone numbers, and an email address are not published. The issue's bio names London and San Francisco. Because the firm's own page lists several offices and does not pick one headquarters, this page does not store a city.
Index's post of Oct. 21, 2026 says the firm is leading Flapping Airplanes' $1 billion Series A. TechCrunch says Index and Lux co-led. The issue says the same. The Index post does not name Lux.
This page is not indexed by search engines yet. It is promoted once it meets the quality gate for investor pages: a description from the firm's own website, a headquarters city and at least two two-sourced rounds on this site.

Raise Track Update for 2026-10-26, Sections 1 and 2. Says Index Ventures co-led Flapping Airplanes' Series A with Lux Capital. The Section 2 bio says the firm is London- and San Francisco-based and backs founders from seed through growth. The contact page lists more than those two offices and does not name one headquarters, so no city is stored and that stage line is not stored as the firm's own wording.
