Matium Head of Marketplace Millersville, MD · Full time Company website

Apply for Head of Marketplace

Founded in 2021 by a former plastics trader and his cousin, Matium is building the digital ecosystem for manufacturers, producers, recyclers, distributors, and traders of raw materials to transact directly with one another. What started in plastics has grown into a rapidly expanding network of over 900 companies — including industry leaders transacting hundreds of millions of pounds of material through the platform. In 2026, Matium is expanding beyond plastics into adjacent markets including paper, metals, and industrial packaging. Matium combines a private CRM/ERP, a verified trading network, a peer-to-peer marketplace with AI-powered matchmaking and auction capabilities, automated freight booking, and embedded transaction financing. Companies can join and trade for free, with premium offerings designed to either fully automate deal execution (“Verified”) or empower internal teams with market intelligence and workflow optimization (“Intelligence”). At its core, Matium exists to modernize how raw materials move — reducing financial waste, operational friction, and unnecessary complexity across global supply chains. We are building long-term market infrastructure, not just software.
