The family runs the daily work.

Decisions are made by the people who carry them out. One accountable owner per area, and the door is never far.

The company record

We learned marketplaces by running them.

Product data, account health, delivery, compliance, advertising and daily pricing decisions. That experience now helps the brands we run enter and grow across Europe without building every local process themselves. The way we work has not changed since we sold our own stock.

Founded 2018 Started as a marketplace seller. We learned the work from the inside before offering it to anyone else.
Leadership Three siblings The founding family still leads the company and stays close to the daily work.

K6 Software

Technology that makes the work clearer.

We build tools around the questions operators face every day: what is selling, what is running out, where margin is changing and what needs attention first. K6 Software is where all of it lands, across every marketplace we run.
