About Diane

Head of Customer Success & Operations – Fractional / Interim Management

I help scale-ups and B2B SaaS companies transform their Customer Success function into a growth lever: reducing churn, improving retention, structuring teams and processes.

With 17 years of experience in demanding B2B environments (PayFit, Jellyfish/Seelk), I have led teams of up to 80+ people and delivered measurable results: NPS improvement, ARR security, churn reduction, structuring of CS playbooks and customer onboarding.

I take on missions when the CS function needs to reach the next level:

- Structuring and scaling CS & Account Management teams
- Implementing CS playbooks, retention strategy, and customer lifecycle
- Customer onboarding and CS–Product–Sales alignment
- Managerial takeover, mentoring managers, and handling sensitive situations

My approach is strategic and operational, with a strong conviction: sustainable performance is built on clear processes, quality execution, and the human engagement of teams.
