DataRoot Labs vs LeewayHertz: overview

DataRoot Labs

Kyiv is home base for DataRoot Labs, founded in 2016 with a stated focus on applied data science research rather than broad IT outsourcing. Sources disagree on staff size, some citing as few as 11 employees and others closer to 200, likely reflecting how contractor networks get counted differently across platforms. What stays consistent across sources is the firm's specialization: machine learning models, computer vision pipelines, and hands-on AI R&D for startups that need research capability without building an internal team from scratch.

LeewayHertz

LeewayHertz has operated out of San Francisco since 2007, though its ownership structure changed in September 2024 when The Hackett Group acquired the company. That acquisition matters for anyone evaluating long-term strategic direction, since it now answers to a larger consulting parent rather than operating fully independently. Public employee figures have also moved in different directions across sources and time, from around 300 in earlier reporting down to roughly 182 by mid-2026, worth checking directly given how much content marketing the firm publishes relative to its actual team size.
