Company History and Business Evolution

Donlen Corporation was founded in 1965 by Don and Len – whose names form the company’s moniker – with a vision to offer personalized fleet leasing services. Starting as a small family-operated business in the Midwest, the company quickly gained traction by focusing on client relationships and transparent pricing. Throughout the 1970s and 1980s, Donlen expanded its service portfolio, adding maintenance programs and fuel management. The introduction of computer-based fleet tracking in the 1990s marked a pivotal shift, allowing the company to deliver unprecedented data insights. In 2000, Donlen launched its proprietary DonlenDriver platform, a web-based tool that gave clients real-time visibility into vehicle utilization and costs. The acquisition of FleetBoss in 2005 strengthened its technology capabilities, while partnerships with GPS providers enriched its telematics offerings. In 2011, Hertz Global Holdings acquired Donlen, providing capital and synergies without diluting the company’s entrepreneurial culture. Post-acquisition, Donlen accelerated its growth, opening new regional centers and investing in electric vehicle (EV) transition services. The company celebrated its 50th anniversary in 2015 by launching sustainability consulting for fleets, helping clients reduce carbon footprints. More recently, Donlen has embraced AI and machine learning to predict maintenance needs and optimize routing. The evolution from a local lessor to a national fleet management powerhouse underscores Donlen’s ability to adapt, innovate, and lead. Today, Donlen manages more than 200,000 vehicles and processes billions of dollars in fleet spend annually, making it one of the top fleet management companies in North America.
