Network of supporters
GEXSI roots back to the 2001 Annual World Economic Forum in Davos, where the initiative “The Global Exchange for Social Investment” was kick-started by a high-level group of individuals, including Klaus Schwab (Schwab Foundation for Social Entrepreneurship), George Soros (Open Society Institute), Kurt Engelhorn (ultra high-net worth individual), Henrik Naujoks (Bain&Company), Hanns-Michael Hölz (Deutsche Bank).
The initiative since then has seen several leading figures, who widened the organisations network:
Before the initiative was transformed into an own legal entity in 2003, the project was managed by the Schwab Foundation’s CEO Pamela Hartigan who now Director of the Skoll Centre for Social Entrepreneurship at Saïd Business School, University of Oxford. Pamela also framed the initial corporate legal set-up, a UK registered limited liability company, GEXSI Ltd, managed by its interim CEO Henry Gonzalez, who, after having worked for 6 years in the microfinance space with Morgan Stanley in London, New York and Paris, joined the Zurich based reponsAbility Investment AG as its head of research in late 2012.
Maritta Koch-Weser has been GEXSI’s long-standing CEO and later chair of the board, framing the organizations focus on the intersection of impact investing and venture philanthropy. Maritta is a world-leading expert in development finance and conservation, who held senior positions at the World Bank (director) and IUCN (director general) prior to taking over the management of GEXSI in 2004.
