Meet the Team

We are Impacc’s impatiant optimists determined to make the tools of business work for social change. People with shared values form a team. Check out our people and values.

Till Wahnbaeck

Co-Founder & CEO

Ex-CEO of Welthungerhilfe and private sector General Manager, champion of innovation.

Till ran both for profit companies and a global NGO and has always strived to bridge the gap between the social and the private sector. As global CEO of Welthungerhilfe (a German food- and nutrition-security NGO with 2,500 staff in 40 countries and a budget of 250mio$), he championed innovation and impact. Previously, as Marketing, Sales and Innovation Director for consumer goods company, Procter & Gamble, he built innovation methods and processes to rejuvenate P&G’s global salon portfolio. 

With his wife Carolin, a journalist, they have three daughters and three chicken. Till is an enthusiastic but sadly untalented surfer and avid urban farmer.

Jochen Moninger

Co-Founder & COO
Addis Ababa

Development expert with decades of experience in building social businesses in developing countries.

Jochen, a human geographer with an Executive MBA from EMST Berlin, is a seasoned development professional who has spent decades working in West and East Africa with local community-based organisations. As country director in West Africa and later Head of Innovation for Welthungerhilfe, he created and led the organisation’s global social business portfolio with award-winning innovations such as the Child Growth Monitor, a new way to detect child malnutrition via digital technology.
Together with his Ethiopian wife and their three daughters, he lives in Addis Ababa and leads our Social Ventures there.
In his youth, he wrote a book explaining global politics as a soccer match, so he typically gets his football analogies right (whereas Till usually gets them wrong).
