iF Sprint Summer '26

​The iF Sprint is a 48-hour experience designed to explore ideas, build teams, and try out what it feels like to create a startup. Over one weekend, you’ll collaborate, experiment, learn from mentors, and present your idea in a final pitch.

​Anyone interested in startups and innovation is welcome to join — students and non-students alike, from developers and designers to marketers, scientists, engineers, and aspiring founders. What matters most is motivation, curiosity, and the willingness to develop a business model from an idea within a short time.

​Do I need to pitch my own idea?

​No, you don't have to join with an idea. Everyone who has an idea gets 60 seconds to present it to the audience on Friday. All participants then vote to determine the 10 best ideas - or the 10 that are most fun to work on for an entire weekend. You can then join a team around one of the winning ideas.

​Are all ideas allowed?

​(Nearly) everything is allowed - even if you think your idea is totally crazy!

​From when to when is the event?

​The event starts on Friday (03.07.) at 16:00 and goes until approximately 20:00 on Sunday (05.07.). Most of the time inbetween - especially on Saturday -, you'll be working in your teams from early in the morning until the evening, with the support of our mentors and workshop hosts. We don't give you super strict times - you are free to figure out within your team when and how you want to work and which workshops you want to attend.

Note: Participants must be at least 18 years old to attend the event. If you already have a startup, then feel free to check out our other programs at impossible-founders.com !
