Open Source in Finance Forum London 2025

Open source thrives on engagement, yet sustaining long-term contributor involvement remains a challenge—especially within large companies. In this talk, we’ll share how we built a strong internal open source community by recognising and rewarding contributors, reinforcing engagement, and fostering a culture of participation. We’ll walk through the strategies we implemented, from career growth opportunities to conference travel incentives, and the use of gamification. In addition, we’ll showcase how we measured the impact of these efforts, demonstrating how recognition fuels retention, innovation, and long-term commitment to open source. Attendees will leave with actionable insights on how to cultivate a contributor-first culture within their own organisations, ensuring open source contribution remains a core part of their company’s DNA.
