BotsCrew vs LeewayHertz: overview

BotsCrew

BotsCrew has built custom AI chatbots and agents since 2016, headquartered in London with additional teams in Lviv, Ukraine, Adelaide, Australia, and San Francisco. Public employee figures range from roughly 60 to 200. The UK left the EU in 2020, so London-based contracting sits outside EU jurisdiction proper, though the agency's Ukraine delivery team keeps it within reach of European clients on a compatible time zone even without an EU legal entity.

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.
