4 upcoming hackathons for founders & investors in Madrid. Curated events across Europe.
Autumn runs hackathon-heavy in Madrid, with no marquee conference until South Summit next June. HackSpain on Sep 18 opens the season, followed by a 48-hour Claude Code Hackathon on Oct 2 for founders building with AI tools. MERGE Madrid on Oct 27 is the nearest conference-format option. South Summit 2027, Jun 2, is the regional flagship: 20,000 attendees, the whole Spanish and Latin American ecosystem in one building.
One email every Monday: the Madrid events worth planning around. Hand-filtered, with the fine print. Nothing else, ever.
