ABOUT ME
I'm Florent, a Fractional Chief Growth Officer and the founder of Leftorn
Why am I doing that ?
Over the past decade, I have led growth and marketing functions across B2B and D2C scale-ups, from Series A start-ups to 400-person organisations, managing marketing, operations, commercial, and product teams.
What distinguishes my work is not channel experience alone. It is the ability to build what sits beneath the channels: in-house attribution models designed from first principles, unit economics frameworks tied directly to P&L, and revenue operating models that make growth repeatable without me in the room.
I have delivered this in HealthTech, hospitality, events, housing, and e-commerce, in France, Germany, the United States, and the United Kingdom.

How It All Started
Most companies have data. Few are data-driven. NewVantage Partners' annual survey of Fortune 1000 executives has found year after year that the main barrier to becoming data-driven isn't technology. It's culture! less than a third report having been able to built one.
Access to dashboards doesn't change how decisions get made.
Clear ownership, decision rights, and incentives tied to data, not opinion, are the foundation of that culture.
Becoming data-driven means rebuilding how a company decides, not just what it measures.
Leftorn exists to lead that transformation. We work inside your leadership team to redesign decision processes, set the right structure, and shift the mindset, so data stops being a report and starts being how the company runs
