Margaret Upshur is CEO of Mobius Materials, a global online marketplace for excess electronic components. Before founding Mobius, she was senior director of operations at Particle, which supplies application infrastructure for deploying software and models on computing or IoT devices. And while in college she cofounded a company that made a hand-held device to detect the alcohol content of liquids. Noting some $15 billion or more is wasted each year in unused or obsoleted components, Upshur founded Mobius to provide a platform for trading excess inventory much in the way Wall Street brokers trade stocks.  We discuss her model for a sustainable, resilient supply chain; why the buyers and sellers on the Mobius platform can trade anonymously; as well as the PCB Community Meetup featuring a panel on the Ever-Changing Procurement Environment Mobius is sponsoring at PCB West on Oct. 1.
