J floor We give brilliant founders the space to gather. A place to meet, commit, and believe before the world does. J floor is a community for founders, anchored around two spaces in the heart of Zurich close to its universities and business hubs. Whether you just finished uni or quit big tech, come to J floor if you are wired to build. No equity, no fees. Everything early-stage fits here: messing around with tech, getting first customers, scaling globally, etc… J floor is the base for solo founders and small teams for the earliest stages.
