About Mathias

👋 Hello, I'm **Mathias**!

As soon as I finished my Master's degree, I dove into entrepreneurship.
👉 A first company, stopped after 6 months — not a success, but an *express training* in acquisition, test-and-learn, and field resourcefulness.

Then asecond companywas born, where astrategic pivotled me to what I deeply love today:
🎯Identifying the right customer problems, designing the matching offer, and scaling.

A few months later, I merged with a production unit.
🧪 I went from a "simple" brand to an **industrial player**, with all that entails:
- Negotiation of large B2B deals
- Rapid product industrialization
- Structuring of field & R&D teams
- And above all:finding the right acquisition channels to sell what we produce.

🚀 Today, we generate15 qualified appointments per week automaticallyand achieve 50% annual growth for the past 2 years.
> Targeted scraping → personalized emailing → onboarding funnel → closing → loyalty.

I have also supported several companies in finding their product-market fit and gaining traction:
✅ Example:FairTrotter→ repositioning on a new target →10 quotes signed in less than 2 monthsafter the pivot.
AM Impact+40% annual growthfrom scratch, thanks to complete mastery of acquisition and the sales cycle.

💡 What I love:finding concrete growth levers, activating the right tools, adjusting offers, and helping teams sell better.
This is what I do today:
- Bycoaching entrepreneurs
- Bytraining teams
- And above all, bygetting involved in the field, where deals are made.

My motivation?Understanding your vision, identifying your customer friction points, and building effective, actionable, and profitable solutions together.

    Petit Roseau was founded in 2021 with the aim of becoming the leading brand of body hygiene products in returnable containers for organic specialty stores.

    A much more relevant positioning
