About Jens

How I can help you

Are you looking for a collaborator to retain your international clients and grow your business? Even though I am starting out as a Customer Success Manager, I know how to help you. Thanks to my certified training, I can create a smooth onboarding journey for your clients, guide them in adopting your solutions, and implement actions to prevent churn. By closely monitoring metrics such as NPS or usage rates, I ensure your clients get the most value out of your product right from the start.

My added value and what sets me apart

My strength is simple: I am new to the CSM role, but I have over ten years of experience in customer relations and sales coordination. Originally from Germany and living in France, I perfectly understand multicultural environments. I am trilingual, speaking fluent German, French, and English, and I also speak Swiss-German. These languages are my greatest asset for building true relationships of trust with clients worldwide and working smoothly with all your internal teams.

My typical projects and deliverables

In my work, I am used to managing concrete projects and preparing clear documents. I have already worked on creating user guides to help clients adopt technical products, and I have facilitated meetings and workshops. I also know how to build CRM dashboards to track activity, analyze client needs, prepare sales proposals, and write guideline sheets or procedures for a network of subsidiaries.
