Intellias vs Sigma Software: overview

Intellias

Most of the IoT experience at Intellias comes from vehicles: navigation, connected-car platforms and in-car software for automotive clients. The company was founded in Lviv in 2002, now lists a US office in Chicago, and employs more than 3,000 people. Its IoT practice also covers smart energy and industrial telemetry. For a buyer building an app around vehicles, chargers or fleets, that automotive depth is the reason to shortlist it.

Sigma Software

Sigma Software dates to 2002 and is part of Sweden's Sigma group, with its legal base in Stockholm and most engineers in Ukraine and Poland. Headcount is in the 1,001 to 5,000 range. Its embedded and IoT unit sits beside automotive, telecom and gaming practices. The Scandinavian ownership appeals to Nordic buyers, while IoT app projects are a modest share of a broad portfolio.
