EPAM Systems vs ELEKS: overview

EPAM Systems

EPAM was founded in 1993 and is headquartered in Newtown, Pennsylvania, with more than 50,000 staff. It is listed on the New York Stock Exchange and works mostly for large enterprises. Connected-product and industrial IoT work happens inside its broader engineering, data and cloud practices. Its scale and compliance are real advantages, but IoT apps are a narrow slice of what it does.

ELEKS

ELEKS was established as a product company in 1991 and now lists Tallinn, Estonia as its headquarters, with most engineers in Ukraine and roughly 2,000 people overall. Its strengths are data science, enterprise software and mobility; IoT work usually appears as part of data or industrial projects. For IoT apps it suits buyers whose main problem is making sense of device data in a business system. It is a weaker fit for device-side engineering.
