ITRex Group vs LeewayHertz: overview

ITRex Group

ITRex has been based in Southern California since 2009, with public headcount estimates ranging from around 221 up to over 250 employees across three continents. The agency pairs AI and machine learning with data analytics and cloud computing, though its published delivery footprint centers on North America rather than Europe, which European buyers should factor into any data-residency planning.

LeewayHertz

LeewayHertz has operated from San Francisco since 2007, though ownership changed in September 2024 when The Hackett Group acquired the company. Employee counts have shifted from roughly 300 in earlier reporting to about 182 by mid-2026. No European office is publicly listed, so EU clients would contract with a purely US-based (now Hackett Group-owned) entity.
