Marc Klein

I am a Senior Account Manager with 4+ years of experience driving strategic client management and revenue growth within SaaS and e‑commerce. I focus on upselling, contract and pricing negotiations at C‑level to improve retention and brand perception.

I manage a portfolio of 20 accounts, including 3 key accounts, and lead cross‑functional projects with Marketing, Product, and Operations to deliver tailored client solutions. I use HubSpot, Proposify, and Freshdesk for CRM, KPI tracking, and reporting, and my work has contributed to measurable improvements in customer satisfaction and the company Trustpilot score.

Earlier, I planned and managed logistics for international motorsport events and coordinated with teams, suppliers, and organizers to ensure smooth operations. I developed cost‑efficient transport solutions and documentation as part of my bachelor thesis, combining analytical thinking with operational execution.

I am multilingual and a quick learner who adapts to new tools such as Salesforce and MS Office. I bring an analytical, customer‑centric approach and strong communication skills, and I am driven to create scalable client success and revenue outcomes.
