The space for founders
to build, connect and grow

What it is

J floor is a community of founders anchored around two spaces in the heart of Zurich; one on campus and one in the business hub.

Whether you just finished uni or just quit big tech this is where you can start building in Zurich. From messing around with tech, to getting the first clients, to scaling your team.

You are welcome to work here for free.
Think of it as a base for the earliest of stages.

Our Story

J floor emerged from a community of 50+ builders at the ETH Student Project House (SPH). Since 2023, this community has quietly become one of the most prolific sources of exceptional founders in continental Europe.

We spent days and nights building at the J level of the SPH, learned fast by building and exchanging insights, and turned projects into growing ventures. We experienced firsthand that success can be just a few launches away.

The recipe for success is simple:
Just let extraordinary people working alongside each other, to turn ambition into companies that matter.
