ABOUT YANN HALLOSSERIE
I help companies unlock growth by combining sharp business development, market expansion expertise, and operational excellence powered by agentic AI and best in class practices/toolsFor more than 15 years, I’ve been supporting IT & tech manufacturers, SaaS vendors and ambitious brands in structuring and scaling their commercial engines. My work spans from launching new products and entering new markets (B2B & B2C) to building robust revenue operations able to sustain fast-paced growth.I specialize in guiding leaders through three critical challenges:• Scaling business in complex SaaS and technical product environmentsFrom crafting go-to-market strategies to building partner ecosystems and optimizing sales cycles, I help companies transform solid technology into predictable, profitable revenue.• Supporting brands entering new markets or launching new productsWhether expanding a product line, targeting a new geography, or shifting from B2C to B2B (or vice versa), I work hands-on with teams to calibrate positioning, distribution models, pricing, and channel strategy.• Boosting commercial productivity using lean methods and artificial intelligenceI redesign sales processes for efficiency, clarity, and speed. With AI-enhanced workflows and lean principles, teams reduce friction, focus on high-value actions, and convert faster—without increasing headcount.My approach is pragmatic, data-driven, and intensely collaborative: one step at a time, but always with a clear strategic direction. I work with leaders who want to accelerate safely, align their teams, and turn innovation into measurable impact.If your company is exploring a new market, preparing a product launch, or looking to elevate its commercial performance through smarter methods and modern tools, let’s talk.
