The UK is fast becoming the go-to destination for experimentation enthusiasts.
In the coming months, more than eight events dedicated to experimentation will take place in London and Leeds.

Already announced for May next year: Speero is bringing the Experiment Live (Austin) format to London and expanding it into a brand-new experience called Circus.
You’ll find these and other upcoming UK events in our calendar on Luma.
