Senior🎓
Top SchoolJon Bretman is a seasoned software leader and co-founder CTO based in London with 12 years of experience building scalable web and mobile services. He scaled engineering teams and architectures at Echo during rapid growth and acquisition, moving from Firebase MVPs to Go, Postgres, Kubernetes and a unified React Native app. At Keel he continues to pair hands-on engineering with strategic product work, focusing on reliable cloud-native systems and operational tooling. His background spans consumer platforms (Lyst, Badoo) and enterprise integrations, including direct work with NHS Digital and McKesson-level transitions. Comfortable bridging product, ops and engineering, he also brings an atypical creative edge—from touring as a professional musician—to his leadership style and problem-solving approach.
