Borys Musielak (Filmaster), Anna Walkowska (Homplex) and Kuba Filipowski (Human Way) established REAKTOR in July 2011. Here’s why they did it: “We wanted to give Warsaw a place where startups can work, collaborate and network. Warsaw didn’t have that before. There were many startup events in the city, but they all focused on knowledge transfer. What we were missing was networking, meeting people and chatting – we believe that’s what helps a lot of start-ups get noticed and eventually helps them succeed!

Currently seven leading Polish startups are REAKTOR residents. Learn more about them below!
