LeewayHertz vs Innowise Group: overview

LeewayHertz

LeewayHertz was founded in 2007 and is based in San Francisco. The Hackett Group acquired the company in September 2024, which changes its ownership structure and long-term strategic direction compared to the independently-run firms elsewhere on this list. Public employee counts have moved in different directions depending on the source and date, from roughly 300 in earlier reporting down to about 182 by mid-2026, which is worth factoring in given how much marketing content the company publishes relative to its verified team size.

Innowise Group

Innowise was founded in 2007 by three engineers including CEO Pavel Arlou and is headquartered in Warsaw, Poland. Employee counts vary by source, from roughly 2,100 to over 3,500, reflecting the scale gap between core staff and the firm's full delivered-project base of 1,300-plus engagements across 60-plus countries. The company covers essentially every current AI service category, including AI agents, generative AI, GPT-based systems, computer vision, and NLP document processing, which makes it broad but less specialized than boutique AI-only firms on this list.
