History
The company was founded in April 2003 in Zurich. The founding idea emerged in 2001, when three professionals from finance and development came together: investment banker Klaus Tischhauser, sustainability expert Leo Bächler, and microfinance consultant Armin Villiger. Villiger and Bächler traveled together through Tanzania and there experienced the impact of microfinance. Tischhauser had travelled a two-year bicycle journey through over 20 African countries.responsAbility launched its first fund—the Global Microfinance Fund—later in 2003. It expanded its thematic scope in 2005 to include sustainable food, and in 2014 to include climate finance.
On May 3, 2022, M&G plc completed the acquisition of responsAbility Investments AG.
