About Mathilde

Do you want to structure, scale, or transform your Customer Success organization into a true lever for growth, retention, and expansion?

I support SaaS, Martech, and Fintech companies in building and optimizing their post-sales organizations, with a direct impact on customer satisfaction and recurring revenue.

I bring a unique dual expertise:
- Building Customer Success teams in scale-ups (from €1M to €10M ARR)
- Structuring complex organizations in unicorn environments (€60M+ ARR, 30+ people).

This experience allows me to intervene in structuring from scratch as well as in large-scale transformation.

I also work on Go-To-Market, Customer Marketing, and product repositioning challenges, particularly in transformation or post-merger contexts. I have led segmentation strategies (Enterprise to SMB), customer lifecycle, and customer communication focused on adoption and value.

My approach is resolutely focused on business impact: improving NRR, accelerating product adoption, structuring customer journeys, and aligning teams around customer value.

🔹 Types of projects I work on:

- Structuring or transforming Customer Success organizations
- Implementing retention and expansion strategies (NRR)
- Designing Customer Journeys and adoption paths
- Auditing and optimizing post-sales processes
- Customer Marketing and Voice of the Customer strategy
- Supporting scale-ups or post-merger companies on the CS function

I am passionate about building high-performing, scalable, and deeply customer-centric Customer Success organizations where every interaction contributes to the company's growth.
