Upstream Festival 2025

On 21 and 22 May 2025, Upstream Festival returns, bringing together everything startups need for growth. Together with our partners and a highly curated group of founders of startups and scale-ups, investors, corporates and policy makers from all over Europe we will gather for this one common goal. The main location for the event is Rotterdam’s pop music venue annabel. Founded in 2020, Upstream Festival has quickly become a well known community-led event for startups. Every year, the event brings together a carefully selected group of over 2,000 founders, investors and change makers with one common goal: to build companies that contribute to a better world. Upstream helps startups and scale-ups with the connections, inspiration and people they need to realize their full potential. With an impressive main program and over 35 side events, the two-day event offers everything startups need to grow.
