About
I am a Customer Success professional with 5+ years of experience supporting B2B clients in SaaS, digital services, and growth-focused companies. My strength lies in building long-term client relationships that translate into retention, expansion, and predictable revenue. Across my career, I have worked closely with founders, sales teams, and product teams to ensure customers achieve real, measurable results. What I bring to companies: • Strong onboarding and adoption processes • Proactive account management • Churn reduction and retention strategy • Upsell and expansion support • Clear communication with technical and non-technical stakeholders • Structured feedback loops between customers and product teams. I have supported international clients across Europe in English, French, Dutch, and German. I value clarity, ownership, and long-term partnerships. My goal is always the same: help customers succeed so the business can scale.
