Hewitt Associates was a global human resources consulting and outsourcing firm. It grew organically in its early years through small acquisitions, but began pursuing larger mergers and acquisitions in 2000. This included acquiring retirement, payroll, and human resources outsourcing companies. By 2010, Hewitt had 2,600 clients making it the largest HR outsourcing provider. However, it faced challenges in 2006 as its outsourcing revenues declined due to contract issues and pricing pressures. Moving forward, Hewitt aimed to diversify its revenues across geographies and client sizes through innovation and cross-selling services.
