Investors, Friends and Advisors

The Tengelmann Group has a long-established tradition to social projects and sustainability. We endeavour to continue these values at Tengelmann Social Ventures GmbH:


Tengelmann Ventures invests in fast-growing young internet companies under the motto “Funding your ideas”. In 2011, we invested in Coffee Circle realising that the concept of social enterprises was an extremely innovative one. Coffee Circle buys sustainable coffee from Ethiopian farmers, and for every kilogram of coffee that’s sold; one Euro is invested in local development projects (e.g. building of schools and wells). As a result of the positive development and response we’ve received, and continue to receive from Coffee Circle, we decided to expand these ventures further.
 Tengelmann Social Ventures GmbH was founded as a subsidiary company of Tengelmann Ventures GmbH and is a 100% subsidiary of the Tengelmann Group. Tengelmann Social Ventures GmbH’s goal is to finance social businesses and to offer support and advice to Social Entrepreneurs. 
 Good social business ideas are often not pursued in the early stages, due to lack of capital and insufficient consultation. We aim to close this gap with our involvement in the early stages. In addition, our goal is to increase awareness of the impact of investment in Germany, and by doing so, hope to gain more investors for our ventures.

Kirabo Jackson
Labor Economist

A labor economist, Kirabo Jackson studies education and social policy issues. His recent work analyzes the role of peer learning in teacher effectiveness and how student demographics directly affect the distribution of teacher quality across schools. He is also involved in a number of projects to understand when and why certain policies that reward teachers—or students—for student achievement improve student outcomes. Another research area involves the role of worker-firm “match quality” and its effects on worker productivity, including evidence that how well a teacher fits with a certain school can be as important as teacher quality for some outcomes. Jackson is also involved in ongoing projects studying the effects of attending single-sex schools in Trinidad and Tobago.

Jackson’s scholarly articles have appeared in the Journal of Labor Economics and Journal of Human Resources among others, and his research has been featured in a number of mainstream media outlets, including The New York Times, USA Today, The Wall Street Journal, and Education Week. Both the Spencer and the Smith Richardson foundations have supported his projects. A faculty research fellow at the National Bureau of Economic Research, Jackson comes to Northwestern after being an assistant professor at Cornell University.
