About

Strategic executive.
Hands-on builder.

15+ years leading B2B SaaS marketing across Europe and North America, always at the intersection of product, commercial strategy, and revenue growth.

Stéphane Castellani

"Revenue is shaped upstream, before demand is declared — building early preference is the competitive game."

I build go-to-market engines for B2B SaaS companies selling technically complex products to sophisticated enterprise buyers. Fifteen years across VC-backed startups and publicly listed software vendors, in data, analytics, and AI markets, across Europe and globally.

My approach is revenue architecture: positioning, demand, and pipeline designed in close collaboration with sales, product, and finance, around shared metrics and predictable outcomes. I've partnered with CEOs, CROs, CPOs, and investors at every stage of company growth, from early category creation to scaling past $100M ARR.

Dual-trained engineer (CentraleSupélec Paris + TU Munich), which gives me an instinct for systems, structure, and measurable outcomes. I use agentic AI workflows daily as a force multiplier for lean, high-output teams, keeping human expertise in the loop on what actually requires judgment.
