DataRoot Labs vs LeewayHertz: overview

DataRoot Labs

DataRoot Labs is a Kyiv-based data science and AI consulting company founded in 2016. Team size estimates vary by source, ranging from roughly 11 to 200 employees depending on whether contractors and R&D partners are counted, but the firm consistently positions itself around applied research and development for data science and AI-powered startups rather than broad enterprise IT outsourcing. Its focus stays narrow: machine learning models, computer vision pipelines, and AI R&D partnerships for companies that need a research-capable team without hiring one in-house.

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.
