PAYC

Paycom Software, Inc.

A maker of cloud-based payroll and human-resources software, Paycom lets businesses run hiring, benefits, time tracking, and paychecks from one online platform. One of the first companies to process payroll entirely over the internet, it was founded in 1998 in Oklahoma City by Chad Richison, who often had to demo his newfangled web system in person to win over skeptical clients. Its Beti feature lets employees double-check and approve their own pay before it's finalized.
