Historic gathering reveals how open collaborative development practices enable teams to harness AI technologies and drive enterprise-wide innovation at scale
NEW YORK, Sept. 24, 2025 /PRNewswire/ — The InnerSource Commons Foundation is celebrating their tenth annual InnerSource Summit on Thursday, November 13, 2025, marking a historic milestone as the first summit to span three continents simultaneously. The landmark event will be hosted at three prestigious venues: IBM’s One Madison office in New York City, SAP’s campus in Berlin, Germany, and Mitsubishi Electric’s Serendie Street Yokohama, Japan, with virtual participation available globally.
The anniversary summit represents the culmination of a decade of growth for the InnerSource Commons Foundation, which has evolved from a small community of practitioners in 2015 to now supporting and connecting over 3,000 individuals from more than 800 companies, academic institutions, and government agencies worldwide.
“This 24-hour global celebration embodies the very principles we champion—open collaboration transcending boundaries,” said Daniel Izquierdo, Chairman of the Board. “We are celebrating by focusing on bringing diverse perspectives and practices to light across the globe. Having three industry leaders—IBM, SAP, and Mitsubishi Electric—host our venues demonstrates the enterprise commitment to InnerSource as a transformational approach to software development.”
The InnerSource approach has gained significant recognition from industry analysts, with Gartner identifying InnerSource as a top strategic technology trend in software engineering. Research indicates that organizations implementing InnerSource practices experience substantial improvements in software quality and development efficiency, with teams that apply these methodologies positioned to significantly reduce time to market.
The 2025 summit will run for 24 hours to accommodate global time zones, featuring presentations, case studies, and collaboration sessions focused on real-world InnerSource implementations. The event will showcase how organizations are successfully applying open source principles and practices to internal software development, breaking down silos, accelerating innovation, and fostering knowledge sharing across teams.
The summit will feature keynote presentations from industry leaders including Katsura Ito, the Commissioner of the Japan National Personnel Authority, Peter Giese, Director of the Open Source Program Office at SAP, and Olivia Buzek, STSM AI for Developers at IBM. The full line-up is expected in the next month as a record number of proposals were received for this milestone event. This unprecedented global gathering represents the evolution of InnerSource from emerging practice to essential enterprise capability, cementing the foundation’s role as the definitive source for collaborative development expertise.
