Copenhagen brands mostly grew through wholesale, press and trade fairs, and that history is the right starting point for a marketplace conversation rather than something to move past. The channel that maps most directly onto how you already sell is Faire, where independent retailers across Europe and North America discover and reorder without a stand at a fair. It behaves like a wholesale catalogue with search and reorder mechanics attached, and it rewards the same things your line sheet does — clear specification, honest lead times, opening order terms that make sense — plus one thing your line sheet has never had to carry, which is imagery built to a platform's format.
The consumer marketplaces are a narrower fit and need naming honestly. Denmark has no Amazon marketplace, so Danish demand on Amazon resolves through amazon.de and amazon.se, which makes Amazon an export channel here rather than a domestic one. Fashion labels have a real route through Zalando. And for interiors, the constraint is physical: Amazon's fee bands are built around size and weight tiers, and a pendant lamp or a dining table crosses into economics that no advertising will rescue. Accessories, textiles, small lighting, care products and spare parts are a different question entirely, and often a good one.
The frame we hold throughout is that a marketplace is rented shelf space. The platform owns the buyer, sets the fee and can change both without consulting you. That is an acceptable trade for discovery — reaching a specifier in Hamburg or a shop owner in Portland who would otherwise never find you — and a poor trade as a destination. So the marketplace is run as the front door and your Shopify store as the relationship, with pricing, pack configuration and the routes home decided deliberately rather than left to whichever channel happens to grow fastest.
