DOX

Amdocs Ltd

A maker of software that runs billing, customer care, and network operations for the world's biggest phone and cable companies, serving customers like Comcast, Verizon, and Singtel. Founded in Israel in 1982 as an offshoot of the Golden Pages phone directory, its name blends "Automated Data Processing" and "Modular Systems." After St. Louis's Southwestern Bell bought a stake in 1985, the company moved its headquarters to Missouri while keeping Israel as its research hub.
