Insperity, Inc.

A professional employer organization (PEO) based in Houston that handles payroll, benefits, and HR for small and mid-sized U.S. businesses—acting as a co-employer for roughly three hundred thousand worksite employees through its HR360 and Insperity Premier services. Founded in 1986 as Administaff by two entrepreneurs who sketched out the idea on a yellow legal pad, it rebranded to Insperity in 2011 to blend "inspiration" and "prosperity." It has sponsored a professional golf tournament since 2004.
