Code for Europe brings change agents called code fellows to cities throughout Europe to help foster innovation around common challenges. In 2013, 10 fellows created 8 apps in 7 cities that are now shared on Github and EuropeCommons.org. Joining as a host city or code fellow can help cities work with citizens and technology to create solutions. The presentation promotes Code for Europe's work of matching fellows with city problems to build open source apps, and encourages attendees to get involved.
