The marketplace agency for brand owners

You own the brand. We run it across Europe.

K6 sells your brand on Amazon, bol.com, Allegro and Kaufland. Your stock ships to our facilities, we run everything in the plan we set together, and you invoice one Dutch partner.

The agency model

Three moves. The rest is ours.

  1. 01
    You send stock

    We tell you which products to send, and in which quantities.

  2. 02
    K6 runs the plan

    Listings, advertising, pricing, stock and customer service.

  3. 03
    You invoice one partner

    One Dutch counterparty. No marketplace logins.

What leaves your desk

Send stock. Everything else becomes ours.

Together we set the plan: which marketplaces, which products, which rules. Then K6 carries it out. All of it.

01

Shipment plans

K6 tells you which products to send and in which quantities. You never have to guess.

Listings and content

Built, translated and maintained on every marketplace we agree on.

03

Advertising

Campaigns planned, run and adjusted week by week.

04

Pricing and stock

Watched daily in one system, marketplace by marketplace.

How the plan stays honest

A plan we make together. Rules we keep.

Everything means everything we agreed: the marketplaces, the products, the rules of the plan. That boundary is what makes the promise serious.

01

One plan

Marketplaces, products and rules are agreed together before anything goes live.

02

One accountable team

The people who set the plan run the daily work and answer for the result.

03

Clear decisions

You can see what changed, why it changed and what happens next.

Not a brand owner?

Two other ways into K6.

Selected wholesale

Suppliers and wholesalers: we buy selected stock outright, after a commercial review. Start with a local file check; nothing uploads until you decide.

Consultancy

Your team runs its own marketplace accounts? We advise on setup, growth and profitability. Your accounts stay yours.

Start with one honest review

Show us the brand. We’ll show you the next move.

We review your products, current setup and margins. If the opportunity is real, we explain the route. If it is not, we say so.
