Softermii vs LeewayHertz: overview

Softermii

Softermii has run out of Los Angeles since 2014, with reported staff between roughly 88 and 120 depending on source and date. Its core identity is custom software and platform development; generative AI is a newer, growing line rather than the founding specialty. Clients get a partner that builds the full surrounding product, not just a generative AI component, at the cost of the depth a dedicated AI-only agency can offer.

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.
