Sophia Opperskalski, Interloom: "a marketplace for sustainable fabrics" Sophia Opperskalski has background in South Asian studies and Integrated Natural Resource Management. Sophia Opperskalski has been working for textile companies, research projects and NGOs in Asia and Europe. She supports textile companies in sourcing sustainable materials and is the founder of interloom. Interloom is the first open B2B online platform that makes (co-)sourcing and selling sustainable fabrics easy. We help designers and fashion brands to discover the most sustainable, cutting-edge materials. By helping to form buying groups we facilitate to collectively order ecologically and fairly produced fabrics to reach minimum order quantities and to source at lower quantities and for better value. For suppliers we offer a great marketing platform to easily present their products to a huge online community.
