LeewayHertz vs Iflexion: overview

LeewayHertz

LeewayHertz has operated from San Francisco since 2007, though its ownership changed in September 2024 when The Hackett Group acquired the company. That's relevant to anyone evaluating long-term strategic direction, since the agency now answers to a larger consulting parent. Public employee counts have also shifted, from roughly 300 in earlier reporting to about 182 by mid-2026, worth confirming directly given the volume of content marketing the agency publishes relative to its actual team size.

Iflexion

Iflexion was founded in 1999 and is headquartered in Denver, Colorado, with a team exceeding 1,000 professionals across a reported 500-1,000 employee band. The agency builds bespoke software for enterprises, SMBs, and startups, with mobile application development, artificial intelligence, and e-commerce platforms as named focus areas. Over 25 years of operating history makes it one of the more established agencies on this list, though AI sits within a much broader custom software practice rather than standing on its own.
