The Lab

Happy City Lab explores collective spaces, creating situations and events that generate participative experiences. These invite you to break your routine and engage in the present moment.

From targeted interventions to events designed for audiences of over 90,000, Happy City Lab places social interaction at the heart of its projects. We transform shared spaces to bring new perspectives to our surroundings.

In Switzerland and abroad, our artistic projects are accessible to all and bearers of joy and emotion. Simple and innovative, they generate extraordinary collective experiences and encourage personal investment in communal spaces.

For more information on Happy City Lab’s mission, see Founder and Director Dan Acher’s recent TEDx talk.
