Tom van Arman is founder and director of Tapp, an agency that develops responsible urban technologies. Van Arman is packed with ideas about the digital city and the role that Tada can play in it. Citizens must be much more involved in the implementation of technology in the public space, says Van Arman. He explains how he uses the Tada principles to realize this in his projects. Entrepreneurs could learn more from each other about developing ethical technology. The Tada platform can act as a library for the exchange of knowledge.

The power of Tada is that it is based on principles, so many people agree with it. At the same time, ethical principles are abstract. Yes, we want a digital city from everyone and for everyone. But how do you put that into practice? A lot of work has already gone into Tada's practical application, for example in partnership with the Municipality of Amsterdam. And now it is time to take the next steps to develop Tada in practice.
