Sipwise - An Ale Company

Speedinvest is a leading European venture capital fund for digital startups. With $100M under management, Speedinvest works side-by-side with early-stage entrepreneurs to build great companies. Thanks to our hands-on model, our global partner network and our operations in Silicon Valley, we have managed to become one of the main focal points for the European startup community. We do investments from pre-seed through Series-A and a big portion of our value-add comes through operational work. We concentrate on projects where we have direct experience, networks, and where we can take a well-defined, intensive operational role, and significantly create value for founders and shareholders.
