About Otrium

Founded and headquartered in Amsterdam, we’re a purpose-led business – we believe all clothing should be worn.

Right now, lots of fashion stays unsold. For the resources that went in and for the people who miss out, it’s such a shame. We’re here to fix this. We are an online fashion outlet marketplace and we tech-enable designer brands to find an owner for every item they produce.

We give brands an online outlet channel and digital tools to smartly connect dynamically-priced end-of-season collections with fashion-lovers. Then we give them the data so they can reproduce most-wanted items.

Our app re-imagines outlet shopping helping customers easily find reduced-price gems. We give end-of-season fashion a new start, which is smarter for the wardrobe, smarter for the wallet and smarter for the industry.
