Devcon 8 Mumbai runs 3 to 6 November 2026 at the Jio World Centre, and NAUT's Devcon 8 page lists 54 teams on its programme. The Ethereum Foundation organises it, Fluid and Base are its 2 flagship supporters, and NAUT holds 139 decision makers at those 54 teams, 56 of them on Telegram.
How this list was built: NAUT captured the devcon.org homepage on 9 October 2026 (the organiser, every supporter logo and the employer of each confirmed speaker), plus 5 community partners that announced themselves on X. We re-checked against devcon.org on 22 October 2026: all 29 supporters and every speaker from the capture are still listed. The 5 community partners come from their own posts on X. The counts come from NAUT's Devcon page on 22 October. It is a source-backed list of teams on the programme, so it does not show who has bought a ticket.
