Witekio vs Sigma Software: overview

Witekio

Witekio was founded in 2001 as Adeneo Embedded and renamed as it moved from embedded components into IoT. Avnet agreed to buy the company in September 2019, when it had about 120 staff in France, the United States, the UK and Germany. The work focuses on embedded Linux, Android for devices, board support and OTA, plus UX designers for on-device and companion interfaces. It is a better pick for the device side of an IoT app than for a standalone consumer mobile app.

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.
