About

Product leader with 10+ years of experience building B2B SaaS and healthcare AI products across Europe and the US. Also open to full-time VP Product / Head of Product / CPO / Senior IC roles (Paris/Remote). My background combines cognitive sciences training (MSc from ENS Ulm, research collaboration at Princeton) with hands-on leadership in regulated AI environments. At Cardiologs (acquired by Philips in a €270M exit), I led the product workstream for a remote patient monitoring platform integrating deep learning ECG analysis into clinical workflows, including coordination of the FDA 510(k) submission process and clinical validation initiatives. I later headed product for a GenAI healthcare platform working closely with engineers and data scientists to translate advanced ML systems into usable, compliant products for pharma and MedTech clients. More recently, I took an executive product & GTM mandate at :probabl (official operator of scikit-learn), partnering with the CEO and CTO to lead product strategy and positioning through a €13M seed round, while helping launch open-source and enterprise ML tool. I also have an editorial and literary background (including publishing and press work), which shapes how I approach product leadership: I place strong emphasis on narrative clarity — in product vision, company positioning, and cross-functional alignment. I tend to do my best work at the intersection of: • Technical complexity • Regulatory constraints • Real user needs aligning multidisciplinary teams around clear product direction. I keep a hands-on practice through small personal prototypes, exploring how AI can make complex health information easier to understand, with a strong focus on privacy and safety. After several fractional mandates and executive product engagements, I’m now looking to commit long-term in a full-time senior AI/ML product leadership role, to own outcomes end-to-end and scale product impact over time (VP Product / Head of Product / CPO / Senior IC). Paris-based; open to remote or hybrid roles.
