NextWorth
NextWorth is an electronics trade-in and recycling service. Users of the service exchange used electronics for cash or discounts on newer models. NextWorth was founded by business students at Babson College in 2005. It started as a commission-based service to help businesses setup online auctions for their used items, then changed its business model to focus on electronics trade-ins in 2006. As of late 2012, NextWorth was one of the best-known and largest electronics trade-in and recycling services in the United States, although it handles only a small percentage of total trade-in traffic.
