Density Ventures is the startup lab and investment vehicle of Stephan Uhrenbacher. We build, invest in and support internet and tech companies that shape people’s behaviour in our cities of the future.
Density – When you increase density, all kinds of interesting things happen. People cross each other’s paths, you create serendipity. Density can reduce pollution. When local economies thrive, communities thrive.
Ventures –  We like companies that grow long term, build great brands and strive to dominate their specific sector.

We currently are not looking for new investments.
