What does a marketplace agency do?

A marketplace agency helps online retailers sell their products successfully on platforms like Amazon, OTTO or Kaufland. This starts with the technical integration of the shop with the marketplace and extends to ongoing management – including listing optimisation, campaign management and continuous performance improvement. In short: a marketplace agency takes care of everything needed to ensure products are not just listed, but actually found and purchased.

Which businesses is OnMarketplaces the right fit for?

OnMarketplaces works with online retailers and brands across the DACH region and Europe – from ambitious D2C brands entering marketplaces for the first time, to established sellers looking to professionalise their existing marketplace presence. What matters is not company size, but the commitment to sustainable growth on the right channels.

What sets OnMarketplaces apart from other agencies?

OnMarketplaces is not an anonymous full-service agency with rotating account managers – but a specialised boutique agency with genuine marketplace expertise. Founder Laura Kürzinger has experienced marketplaces from both sides: on the platform side at Conrad Electronic SE and on the brand side at leading e-commerce companies. This combination of platform know-how and retailer perspective is rare – and makes a real difference in both strategy and execution.

Which countries and marketplaces does OnMarketplaces cover?

OnMarketplaces primarily serves retailers in the DACH region and supports them in selling across more than 150 European marketplaces – including Amazon, OTTO, eBay, Kaufland, Zalando, AboutYou, Conrad, Hornbach, OBI and bol.com. For retailers looking to grow internationally, the most promising platforms are selected based on their specific product range and target markets.

How do I get started with OnMarketplaces?

The first step is a free initial consultation – no commitment, no preparation needed. Together we analyse where you currently stand, which marketplaces make sense for your product range and what a realistic strategy looks like. This is followed by an individual proposal and, if there is a mutual fit, a joint kick-off. Simply get in touch and let's get started.

Do I need to manage the marketplaces myself when working with OnMarketplaces?

No – that is the core of the full-service approach. OnMarketplaces handles the technical integration, ongoing management, optimisation and campaigns. You stay in control of your business, while OnMarketplaces takes care of your marketplace presence. This allows you to focus on your core business – knowing that your marketplace channels are in good hands.

How quickly will I see results?

It depends on where you are starting from – and what you consider results. Initial improvements in visibility or first sales can become apparent within a matter of days. Sustainable marketplace success, however, is a long-term endeavour: healthy growth, stable rankings and profitable revenue are built through continuous optimisation – not overnight. Together we develop a strategy that keeps both short-term quick wins and long-term goals in focus.

Does OnMarketplaces also work with businesses that have never sold on marketplaces before?

Yes – and that is actually an ideal starting point. Those who begin with professional guidance from day one avoid common beginner mistakes, save time and money, and build a solid marketplace presence from the ground up. OnMarketplaces guides the entire process – from selecting the right marketplaces and technical integration through to the first sale and beyond.
