About Jan

For over 20 years, I have been supporting companies in building, scaling, and operationally optimizing e-commerce and marketplace businesses – pragmatically, hands-on, and with a clear focus on profitable growth.

My focus is on Amazon, marketplace expansion, performance marketing, and the combination of commerce strategy and operational implementation. Throughout my career, I have built and developed e-commerce structures with cumulative revenues in the up to nine-digit range. At Enders, I was instrumental in building the D2C and marketplace business from €0 to approximately €30 million in annual revenue.

I do not work as a classic "agency" but as an experienced commerce partner on equal footing. Many companies have good products and strong brands but struggle with operational complexity, a lack of marketplace expertise, or inefficient processes. That's exactly where I come in.

My focus areas:
• Amazon Seller & Vendor Central
• Marketplace Expansion (Amazon, eBay, Kaufland etc.)
• Performance Marketing (Amazon PPC & Google Ads)
• SEO, Listing Optimization & Conversion Increase
• Content and Assortment Optimization
• KPI Analysis, Profitability & Growth Strategies
• Remote collaboration with high personal responsibility

Industry experience:
Camping & Outdoor, Mobility/Bicycle, Industrial Products, Wholesale and technically oriented B2B environments.

I have been working successfully remotely for many years and value clear communication, pragmatic solutions, and efficient collaboration without unnecessary complexity. My aim is not "more marketing" but measurable results: better visibility, more profitable campaigns, and sustainable growth.

If you are looking for an experienced e-commerce and marketplace specialist who can think strategically and deliver operationally, I look forward to connecting.
