Startup Nights is Switzerland's biggest startup event, held every November at the Eulachhallen in Winterthur. What began as a gathering of eight people at a bar has grown into a two day festival expecting around 9,500 founders, investors, and enthusiasts for its tenth edition. From 2026 the event is co hosted by the Swiss Startup Association, which is folding it more tightly into the national startup ecosystem. Keynotes, pitch competitions, and networking sessions run under this year's motto, Make It Matter.
