Cellbie develops innovative solutions for the mobile device trade-in industry. Our premise is simple – the market for used cell phones is maturing, and advanced tools are needed to accelerate its growth. We’d like to see this growth happen as quickly as possible, so we’ve built a platform that connects buyers and sellers of used devices. It’s used in retail environments to deliver consumer trade-in, and in wireless retail back-office environments to deliver business to business (B2B) trade-in.
