Hi there!

We’re Dan (UK) and Saki (JP) and together we form Playfool! We create internationally-recognised products and experiences that embrace a core theme of play. Combining our experience in engineering and design, we work both internally and with clients to bring projects from research to idea to prototype.

We believe play has the power to engage people in unusual and innovative ways, and it is our mission to show how embracing a little play can make a big impact.
