LeewayHertz vs Exadel: overview

LeewayHertz

LeewayHertz has operated out of San Francisco since 2007, though its ownership structure changed in September 2024 when The Hackett Group acquired the company. That acquisition matters for anyone evaluating long-term strategic direction, since it now answers to a larger consulting parent rather than operating fully independently. Public employee figures have also moved in different directions across sources and time, from around 300 in earlier reporting down to roughly 182 by mid-2026, worth checking directly given how much content marketing the firm publishes relative to its actual team size.

Exadel

Exadel was founded in 1998 and is headquartered in Walnut Creek, California, with a reported headcount between 1,001 and 5,000 employees. The firm lists AI and data management as one of five core service areas alongside strategy consulting, digital experience, digital products, and managed services, reflecting a broad technology consultancy rather than an AI-only specialist. Over 25 years of operating history gives it a longer track record than most firms on this list, though that history is in general enterprise software delivery, not AI specifically.
