Our purpose

Otrium is a purpose-led business – we see a future where all clothing is worn.

Every year, billions of items are produced globally but are never sold. Clothing goes unworn and often ends up in landfills. This is a huge waste of creative energy, labor, natural resources and investment. Otrium is changing fashion from the inside out: we are an online fashion outlet marketplace and we tech-enable designer brands to find an owner for every item they produce.

Our global business

Founded in Amsterdam and headquartered in the cloud, Otrium also has hubs in New York and London. As a digital-first company, we work around the globe and don’t need to limit our HQ to one location or a single hub. We want to ensure our O-team can work in a way that best fits their needs, whether that’s remote-first, hub-first, or hybrid (50/50). 

Otrium is also committed to fostering an inclusive and diverse community of employees with a strong sense of belonging. We believe we are bettered by all forms of diversity, and take pride in working with talent from every walk of life and corner of the world. In the spirit of inclusivity, qualified applicants will be considered without regard to age, ethnicity, ability, gender, gender expression, gender identity, nationality, race, religion, or sexual orientation.

Here’s to freedom, flexibility, and global inclusivity!
