Zurich's real calendar starts in November, when two big summits land eleven days apart. Startup Nights (Nov 5, in Winterthur) is Switzerland's biggest startup event, with about 9,500 attendees and 150 pitching startups. The Swiss AI Summit (Nov 16, Kunsthaus) is the one to pick if you sell into regulated industries, since it covers AI deployment without giving up data sovereignty. Before that, ETH Entrepreneur Club's InCube Finale (Oct 30) and LAUNCH (Nov 3) are the builder-side draws.
