Startup & tech events in London

143 upcoming startup & tech events in London: networking nights, founder meetups, pitch events, demo days & more. Updated daily.

Sifted Summit on Sep 30 is the draw; the opening week has genuine builder content. Encode Club's Battle of the Accelerators on Sep 3 puts YC, Speedrun, EF, and Techstars on the same stage for a direct fund comparison. OpenAI also runs a Builder Lounge in London on Sep 3, and an Encode AI hackathon follows on Sep 5. Sifted Summit itself draws 1,500 founders and 200+ investors into a roundtable-heavy format, the closest thing Europe has to an annual founder reunion.

One email every Monday: the London events worth planning around. Hand-filtered, with the fine print. Nothing else, ever.
