Grid Dynamics vs LeewayHertz: overview

Grid Dynamics

Grid Dynamics has traded on Nasdaq as GDYN since March 2020, more than a decade after its 2006 founding. As of mid-2026 it reported approximately 4,838 personnel across the US, UK, the Netherlands, Mexico, Switzerland, and Central and Eastern Europe, with the Netherlands presence putting a legal foothold inside the EU. AI-powered digital engineering is marketed as a core practice, and public-company status gives European enterprise buyers financial visibility most agencies on this list can't offer.

LeewayHertz

LeewayHertz has operated from San Francisco since 2007, though ownership changed in September 2024 when The Hackett Group acquired the company. Employee counts have shifted from roughly 300 in earlier reporting to about 182 by mid-2026. No European office is publicly listed, so EU clients would contract with a purely US-based (now Hackett Group-owned) entity.
