Brandback

Brandback is a Berlin-based embedded resale infrastructure company (legal entity Arbor Technologies GmbH) that lets online retailers and fashion brands integrate resale directly into their baskets, product listings, and checkouts. Shoppers see an item's future resale value before they buy, resell it later in a single click, and receive store credit, while Brandback's AI handles pricing recommendations, condition checks, customer service, shipping, disputes, and payouts. Retailers can launch a white-label resale marketplace with no upfront cost and integrate with any e-commerce platform. Founded in 2023 and backed by $7.4M in pre-seed and seed funding led by Earlybird VC, Brandback reports a 9.5% average conversion-rate lift with customers including Replay Jeans and Sandqvist.

Brandback is profiled on the APIs.io network. Tagged areas include Company, Resale, Recommerce, E-Commerce, and Retail.

Brandback’s developer surface includes documentation, support, and 8 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/brandback: open an issue to ask a question, or submit a pull request to add artifacts.
