Alterra Impact Finance GmbH is a Swiss-based investment, investment advisory firm and consultant for social impact investments and enterprises.  Established in 2011, Alterra has made direct investments in socially responsible business as well as advising a UK-based impact investment company and selected clients.  Investments are focussed on European companies with explicit positive social and environmental impacts. Presently, the partnership is fully invested, and is supporting business development activities for its portfolio companies.

We believe that impact investing is an important development that benefits not only enterprises, but investors and society as such.  Therefore, Alterra also supports the emergence of impact investing through education, consulting and industry-related events. Impact investments are now being integrated by leading US and European banks, pension funds, foundations and family offices into traditional investment portfolios.

Alterra’s consulting activities are directed to organizations and enterprises that have meaningful social impact, and generally focus on strategy, market positioning, finance and fund development, and governance.

Alterra Impact Finance draws on a broad network of individuals and organizations in diverse sectors for specific thematic and investment expertise.  We have experience in both traditional and venture philanthropy and impact investment well as expertise in governance and organizational strategy.  Our business portfolio includes selected institutional advancement support , engagement with our portfolio investee companies and individually structured private client mandates.
