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 19–22 June (concurrent to TOA18), top thought-leaders come together for a series of carefully curated events and one-of-a-kind experiences, in unique venues across Berlin.
