Our History
SEIF has a longstanding history as an impact venture accelerator with a pan-European focus. Founded in 2011 by Prof. Mariana Christen Jakob with the aim of professionalizing the social entrepreneurship sector and providing impact startups with the necessary support to grow and scale successfully.
Over the past 10 years, the SEIF team has built an extensive pipeline and database of impact driven entrepreneurs, whereby a significant gap in external capital made available for early-stage impact ventures in need of first-time financing has been observed.
