About Madrid · October 2026

Madrid is a quiet stretch, and the first real builder date is a November hackathon. Near-term listings are mostly recurring Sunday runs and a Claude community meetup. The Agent Pay Hackathon by MERGE on Nov 27 is the one to build around, with MERGE Madrid on Oct 27 the only conference before it. The main draw, South Summit on Jun 2, is still eight months out.
