Tessel van LeeuwenConcept Developer

Tessel van Leeuwen is a concept developer with Waag Futurelab. Here, she focuses on social issues around digitisation, participation and the democratisation of technology. Among other things, she does this by questioning the social side of technology together with target groups and then integrating that into design. Her focus is on the development of sustainable public-civil partnerships and data commons as a central component of the community economy: an economic model in which cooperation and an emphasis on people and social and/or environmental goals over profit are central. 

Previously, Tessel was project manager of the Code and Interface team at Waag. Tessel studied Cultural Heritage at the Reinwardt Academy (BA) and completed the part-time master's in Urban Management (MA) in 2022.
