Fractional CMO for Creative, Luxury & Purpose-Driven Brands

Your Challenges?

You wish you had one more day — every day?

Stuck in the Day-to-Day

Your internal teams are focused on delivery, leaving little time or space to think long-term or step back with perspective. Strategy keeps getting postponed.

Missed Strategic Windows

Opportunities come and go. But without someone to analyze, align and act quickly, you miss key moments to grow, pivot or innovate.

No Budget for Full-Time

You need senior marketing guidance to move forward with clarity and impact — but can’t afford, justify or secure approval for another full-time hire.

Global Vision, Local Gaps

You’re expanding internationally, but lack someone who speaks both the brand’s language and the cultural nuances — especially between Europe and the U.S.

Let me be your fractional CMO

From launching a side initiative to navigating market change or leading cross-border collaborations — get strategic support without a full-time hire.

Launch & Repositioning

Refocus your brand and design a clear go-to-market strategy.

Brand Growth

Scale with purpose while staying true to your brand DNA.

Brand Collaborations

Create strategic alliances that elevate visibility and impact.

Hi! I am Céline,

your CMO for a day...

(or more!)

With nearly 20 years of experience, I help brands grow across borders, markets and disciplines — blending strategy, creativity and execution.

Based in the U.S. with deep roots in France, I bring a cross-cultural perspective shaped by years of working in luxury, visual arts, fashion and tech. I thrive at the intersection of big-picture thinking and agile action — helping brands move forward with clarity and momentum.

I’ve supported startups, accelerators and iconic brands through key growth moments: product launches, brand repositioning, international expansion, fundraising, and creative partnerships. Whether you need structure, vision or execution — I step in where it counts.

Let’s write your next chapter, together.
