Summary
🤩
Rockstar🎓
Top SchoolXavier Damman is a tech entrepreneur and steward with 15+ years building platforms that empower communities to self-organize, collect funds transparently, and rebuild the commons. He co-founded Storify (acquired by Livefyre/Adobe) and Open Collective, and today leads efforts at Open Collective, Commons Hub Brussels and Citizen Wallet to design web3-native community currencies and tooling for local resilience. Equally comfortable in frontend and backend code, his open-source contributions range from improving Handlebars and CSS tooling to hardening Open Collective’s GraphQL API and PayPal flows. A Belgian-based engineer and community organizer, he turns civic technology into practical civic infrastructure—running street-level projects like Citizen Spring and a temporary community hub that incubated Regens Unite. Notably, he blends product instincts with grassroots activism to shift incentives from extraction toward regeneration, freeing communities to capture value beyond shareholder returns.
