AI Launchpad

Europe’s Network for Nurturing AI Startups: As initiators of the AI Launchpad, we built this program in collaboration with the ETH AI Center so they are part of a leading, Europe-wide platform for the targeted acceleration of research-driven, deep-tech AI startups. AI Launchpad connects Europe’s top AI hubs, supports ventures on their path to market, and provides intensive programs featuring specialized workshops, hub visits, and targeted customer introductions.
