LeewayHertz vs DataArt: overview
LeewayHertz
LeewayHertz has operated from San Francisco since 2007, though ownership changed in September 2024 when The Hackett Group acquired the company. That's relevant to anyone evaluating long-term direction, since the agency now answers to a larger consulting parent. Employee counts have also shifted, from roughly 300 in earlier reporting to about 182 by mid-2026, worth confirming directly given the volume of generative AI content marketing the agency publishes relative to its actual team size.
DataArt
DataArt goes back to 1997, founded by Eugene Goland, and is headquartered in New York City with roughly 5,700 employees spread across more than 30 locations. The firm delivers data, analytics, and generative AI platforms for finance, media and entertainment, healthcare, retail, and travel and hospitality clients. Nearly three decades of history gives it a longer track record than almost every other firm here, though generative AI is delivered as part of a broader software engineering practice rather than a standalone specialty.
