Our take

Founded in Ukraine in 2013, EchoGlobal Tech has since grown into an international staffing agency focused on tech and IT. It helps companies source the right staff for the right projects and has worked with the likes of Platinum Group, Litera Microsystems and even a Fortune 500 firm.

EchoGlobal Tech has enjoyed significant growth over the last decade, despite the ongoing war in its home country. 2022 saw it achieve a 36% growth in its staff and a 51% revenue increase, indicating its health as a talent sourcing platform. With clients across Europe, the UK and the US, it looks set to continue on its impressive trajectory.
