FIS

Fidelity National Information Services, Inc.

A global financial technology company that builds banking, payments, and trading software used by banks and financial firms worldwide. Its roots go back to 1968, when a former IBM engineer founded Systematics, Inc. in Little Rock, Arkansas to run data centers for mid-sized banks. The FIS name arrived in 2003 after title-insurance giant Fidelity National Financial bought that business. Fun fact: FIS bought the payments processor Worldpay in 2019 and sold most of it in 2024.
