Not an agency

Be bold

Your AI-augmented fractional CMO, amplifying your marketing & communication end to end

Expertises

Combining strategy, tools and content production is essential for your marketing to truly serve your business. Usually, the work is split: a consultancy for strategy, an agency for visuals, a freelancer for technical work. And it gets even more complex with the new channels — you need to be present everywhere, consistently. The result: disconnected campaigns, fragmented audiences, no one to tie it all together. I built these three areas of expertise step by step: first as a digital strategist in agency, then as marketing director at an IT and AI group. From this journey came my method: running your marketing end to end, with no break between decision and production.

Fractional CMO

I run

I become your fractional CMO. I decide the strategy and execute it myself — with my fine-tuned AI agents and partner network. For: SMEs and mid-market companies without an internal marketing team, who want marketing that runs without the mental load.

I Support

I join your existing marketing team. I structure it, train it, transmit my method and tools — so it gains autonomy and cadence. For: Mid-market companies with a team in place that want to accelerate their transformation without hiring an in-house CMO.
