Coders, designers, and entrepreneurs in and around Krakow, Poland! AngelHack invites you to sign up to participate in the AngelHack Global Hackathon Series: Krakow. Compete on your own, or collaborate as a member of a team to come up with an idea and turn it into a functioning prototype. This year’s theme is Seamless Technology. You're not limited! Build an app that solves a social or environmental problem and positively impacts your local community -- you might win the Code For A Cause Impact Award. Or just build something innovative without limits, something that brings positive change to the world, or whatever your imagination can conceive.
