SEIF supports and promotes impact driven entrepreneurs – individuals or teams – with innovative business ideas to solve current social and/or environmental challenges. With a main focus on TECH FOR IMPACT, we provide targeted support for impact entrepreneurs to grow, improve their business performance and scale their impact.

Together with our corporate partners, we lead the TECH FOR IMPACT Awards, a Europe-wide business plan competition for impact driven tech entrepreneurs. Twice a year we run the IMPACT ACADEMY which is linked to our Angel network Impact Investors Circle. We are the only organization in Switzerland certified to run Innosuisse trainings for Social Entrepreneurs, in collaboration with ZHAW and EPFL.
