Sustainable growth,
built with people,
not hacks.

I'm Arnaud, a growth leader with 15+ years across B2B, B2C and PLG, unifying sales, product and marketing under one growth lens. I build high-performing teams that test, learn and ship, and now use AI agents to help them move faster and reach further.

02, Philosophy

Growth comes from understanding users, challenging common beliefs, daring to fail, and repeating.

The biggest wins come from great people and a 360° mindset, breaking the walls between sales, product and marketing. My focus is on sustainable growth, not short-term hacks, and on teams empowered to challenge the status quo. This means creating a clear framework and psychological safety where "failing" is part of our daily routine, because it means learning, and learning is growth.

03, Teaching what I practice

AI course for product & growth people.

I built a course to help product and growth people become AI-fluent, with concrete use cases, prompts and workflows they can apply on day one.
