Senior Product Manager based in Tokyo since 2022, with 10+ years of product experience between France and Japan: co-founder and CTO of Simplauto (leading technical inspection comparison platform in France, 1M+ annual visitors), then senior PM within Japanese tech companies (adtech, agritech).
I work on two types of missions:
Product Management
I support your product teams throughout the entire process: discovery, roadmap, prioritization, analytics, optimization, A/B testing, integration of generative AI into product workflows. Hybrid product/technical profile: I speak the language of your developers and deliver autonomously.
Development in the Japanese market
I help French companies adapt their product and digital strategy to Japan: market research and competitive analysis, product and UX localization for Japanese users, SEO and content strategy in Japanese, benchmark of local usage. I live the Japanese market from the inside: I am currently building my own B2C media brand there (Instagram, podcast, newsletter, web platform), with a 100% Japanese SEO and content strategy.
