An annual four-day interdisciplinary technology festival held in Berlin, bringing together founders, investors, scientists, and creatives across deep tech disciplines including AI, climate technology, synthetic biology, Web3, and health technology, with programming that spans talks, workshops, hackathons, and cultural experiences.
TOA Berlin (Tech Open Air) is an annual four-day technology festival organised by Berlin-based Tech Open GmbH. The event brings together founders, investors, scientists, and creatives to explore deep tech themes including AI and advanced computing, climate technology, synthetic biology, Web3, and health technology. Its format is deliberately interdisciplinary, combining conference-style programming with workshops, hackathons, exhibitions, and cultural experiences in the Berlin tradition.
TOA Berlin operates as a broad-church technology festival rather than a single-sector conference, making it distinct from many vertically focused European events. The festival combines serious technical and investment programming with music, art, and cultural elements reflecting its Berlin setting. Since inception the festival has generated more than 500 satellite events that extend the programme across the city, distributing content beyond a single venue and enabling smaller community-led gatherings to run in parallel. Tech Open GmbH has since taken the format to Los Angeles, Tokyo, and Austin, but the Berlin edition remains the founding event and the largest in scale.
The confirmed speaker roster comprises 80 named speakers across the programme, spanning venture capital, deep tech founding teams, AI research, and Web3 infrastructure.
| Expected attendees | 15,000 (organiser figure) |
| Confirmed speakers | 80 |
| Festival duration | 4 days |
| Satellite events (since inception) | 500+ |
TOA Berlin operates as a multi-day festival rather than a conventional conference, intentionally combining technical programming with music, art, and cultural experiences. The satellite event model, where community-organised gatherings run across Berlin during the festival period, distributes participation beyond a single venue. The presence of creatives and scientists alongside investors and founders reflects a broader-than-usual attendee mix for a B2B technology event.
No. The festival covers six thematic tracks: AI and advanced computing, climate technology, health technology, synthetic biology, Web3, and business success. It is positioned as an interdisciplinary event, and the speaker roster reflects participation from across these verticals rather than depth in any single one.
