Density Ventures is the investment vehicle of Stephan Uhrenbacher.
We invest mostly in North America, focusing on the Canadian AI and deep tech space. We write small cheques and help making companies investable for others. Having built, scaled and exited several startups, Stephan has a unique experience as an operator. While many founders rely on mentorship from Stephan, Density Ventures typically is a “hands off” investor.
