Coherent Solutions vs LeewayHertz: overview

Coherent Solutions

Coherent Solutions was founded in 1995 by Igor Epshteyn in Minneapolis, Minnesota, and reported roughly 2,200 employees as of 2023. The company runs offshore development offices across Belarus, Bulgaria, Moldova, Mexico, Lithuania, Ukraine, Romania, Georgia, and Poland, four of which (Bulgaria, Lithuania, Romania, Poland) sit inside the EU. Its core business is software product development and consulting, with AI delivered as part of that established 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.
