Launched by TOA in 2016, Open Circle is a bespoke event program designed for a select group of TOA speakers, investors, partners, innovators, tech luminaries, influential artists, scientists and media.

Over four days between 2–5 July (concurrent to TOA19), top thought-leaders come together for a series of carefully curated events and one-of-a-kind experiences, in unique venues across Berlin.

Welcome to Open Circle 2019

If you would like to attend Open Circle this summer, please submit your application and we will be in touch with more information.

OC attendance is based on a successful application as well as a ticket fee to access 4 days of immersive content and high-level networking

We have some exciting news for you: Mathias Döpfner, CEO of Europe's largest digital publisher Axel Springer, has become Chairman of Open Circle. Together we seek to build an intimate community of global thought-leaders and continue to connect leading technology ecosystems with one another.
