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'm a strategic and hands-on global B2B SaaS marketing executive with a proven track record in building scalable go-to-market strategies, delivering sustainable revenue growth, and establishing category leadership in data, analytics, and AI.

I combine deep product, technical, and commercial expertise to align marketing, sales, and product teams around shared goals — acting as a trusted executive partner to CEOs, boards, and investors, owning company narrative and end-to-end growth across acquisition, expansion, and retention.

Dual-trained engineer (CentraleSupélec Paris + TU Munich), which gives me an instinct for structure, systems, and measurable outcomes — applied to every marketing and revenue challenge I take on.
