Senior🎓
Top SchoolIvan Bertona is a product-focused CTO and founder with 11+ years of hands-on engineering and leadership experience across Europe and the USA, currently leading Beside from Paris. He started his career at Google and has since built and scaled engineering teams and products at seed- and growth-stage startups, most notably co-founding Wellplæce and raising $5.5M to deliver a SaaS procurement platform for dental practices. Technically versatile, he spans backend, APIs, big data, DevOps, IoT and security, and has contributed security-focused code and tests to the well-regarded smallstep/certificates open-source project. Known for combining deep technical execution with product and business intuition, he has repeatedly shipped first-version backends and integrated software-hardware products in constrained, fast-moving environments. Fluent in both startup scrappiness and disciplined engineering practices, he excels at turning ambiguous problems into production-grade systems. An unusual detail: early-career work included porting an OS to SPARC as a master’s thesis, signaling a comfort with low-level systems as well as cloud-scale services.
