Rockstar🎓
Top SchoolMathieu Godart is a Paris-based technology leader and serial founder with 14 years of experience bridging mobile engineering and product strategy as Co-founder & CTO of SEMEIA and founder of Lauve. Trained as an engineer at Télécom Paris, he cut his teeth in ASIC design and hardware integration before shifting to mobile and backend systems, bringing rare cross-domain depth from silicon to iOS apps and server-side services. A longtime iOS contributor, Mathieu has improved notable open-source projects like NSLogger, kxmovie and Shopify’s SuperDB—adding Swift wrappers, UI refinements and richer debugging and image-handling features that reflect his focus on developer experience. He also cultivates the French Apple ecosystem as an organizer of CocoaHeads Paris, FrenchKit and industry events, blending community-building with hands-on R&D experience from Criteo and entrepreneurial product work. Not obvious at first glance: his background in ASIC engineering informs a pragmatic, systems-level view of performance and tooling that shapes both product architecture and developer workflows.
