Our Founding Story

Since then, Expa has launched over a dozen companies and supported more than 50 entrepreneurs. Expa’s community has grown to over 300 people internationally.

Why Founders Choose Us

The Expa network is far-reaching. Founders have access to top US and European investors, and can tap into existing relationships with top design & product development firms.


With offices in San Francisco, New York, Los Angeles, Vancouver, and London, Expa offers a physical place for entrepreneurs to come together, collaborate, and share knowledge.


Expa supports founders with early-stage capital to get projects off the ground, as well as access to follow-on capital.
