HYS Enterprise vs LeewayHertz: overview

HYS Enterprise

HYS Enterprise was founded in 2007 and is headquartered in Amsterdam, Netherlands, an EU member state, with its main development hub staffed by engineers based in Poland, also within the EU. As of mid-2026 the company reported 213 employees. Both its legal headquarters and primary delivery hub sit inside EU jurisdiction, a combination fewer vendors on this list can claim, with AI delivered as an extension of its general consulting and engineering practice.

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.
