InnerSource Summit 2025 - Berlin

Ready to transform how your team builds software?

Imagine this:Your developers stop reinventing the wheel every sprint. Teams openly share their best work. Knowledge flows effortlessly across departments and locations. Sounds impossible? That’s the magic of InnerSource!

InnerSource helps people collaborate by sharing code, documentation, automation, and clever solutions that usually stay hidden. The result? Teams working smarter (not just harder), productivity gains everyone can feel, and that great moment when your work makes a difference beyond your own team.

And here’s a stat worth noting: organizations embracing InnerSource have reported productivity boosts of up to 87%. Not a typo — that’s what happens when talented people collaborate instead of compete! 🚀

At the heart of this movement is InnerSource Commons (ISC) — a global community of practitioners who share what really works (and what doesn’t) so everyone can benefit.

This isn’t just another corporate conference. It's a 10-year celebration packed with real stories, practical tips, and genuine connections:

🌟 Hear how teams have transformed their development culture

🛠️ Learn proven techniques from people who’ve actually made it work

💡 Share your successes (and your toughest challenges) with peers who understand

🤝 Connect with fellow developers, architects, and managers who care about better collaboration

☕ Enjoy chatting with people who speak your language — tech and otherwise!

Whether you're the developer quietly practicing InnerSource, the team lead trying to break silos, or the manager exploring new ways to foster innovation — this summit is for you.

Come for the knowledge, stay for the community. Leave with fresh ideas, new friends, and that renewed energy that comes from knowing you're not alone in wanting to build software that truly makes a difference.
