CEI-Sphere: Connecting Communities at Open Source Community Day 2025
On 23-24 September, Madrid will serve as the European hub for open source innovation with the Open Source Community Day 2025.
Co-organised by CEI-Sphere and the Eclipse Foundation, and co-located within the AIOTI Days, this event will unite industry leaders, open source communities, and key EU-funded research initiatives for two days of dynamic dialogue, knowledge sharing, and networking.
Today, 70–90% of all software integrates open source components. From AI and IoT to cloud infrastructure and e-Government tools, open source underpins nearly every digital system. Yet, this essential layer often lacks the governance, funding, and visibility required to align with Europe’s values, standards, and ambitions for strategic autonomy.
A key question arises: How can Europe move from being primarily a user to becoming a global leader in open source governance and standardisation?
Why Join the Event?
Positioned as a strategic meeting point for Europe’s digital future, the event offers participants a unique opportunity to understand and build connections with influential open source communities and leading EU research projects. Attendees will see innovative technologies in action through cross-domain demonstrations and use cases, explore how open collaboration and standardisation efforts can reinforce one another, and engage in timely discussions on policy, sustainability, and the real-world adoption of open technologies.
The event is targeted at developers, researchers, policymakers, and industrial stakeholders interested in advancing open source collaboration across Europe.
The programme will feature insightful keynote speeches, expert panel discussions, and a poster exhibition showcasing industrial contributions and outcomes from European research projects. CEI-Sphere is also hosting a community session where participants can showcase their research, open source initiatives, and project outcomes. If you want to share your work with the broader community, bring your roll-ups / flyers!
