Plex is an ERP system developed for an auto parts manufacturer and expanded to address issues in several industry verticals. Purchased in June 2012, Plex is owned by Francisco Partners, a private equity group specializing in high tech business. Plex’s main office is in Troy Michigan and has about 300 employees with about 850 clients; each client may have multiple installs. Plex Systems powers over 1,100 plants in 20 countries with a 95% renewal rate. Plex provides its entire ERP solution via an online service, meaning users need nothing but a log-in and a web browser to get started. Unlike retrofitted solutions that claim to be in the cloud, Plex provides a single technology stack to all of its customers, meaning lower costs, higher scalability, and access to continuous innovation.
