Its own company report put the team at 447 people in mid-2022. Connected-device projects joined its mobile and web work around 2014, and it now publishes on AI, AR and IoT. Most of its IoT strength sits in the app and data side rather than in firmware or hardware.

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.
