Witekio vs Sigma Software Group: overview
Witekio
Witekio began as Adeneo Embedded, founded in Lyon, France in 2001, and rebranded to Witekio as it grew its embedded Linux and IoT software practice across Europe and North America. Avnet, a global electronics distributor, acquired the company in September 2019 to add embedded software depth to its IoT hardware distribution business, and Witekio now operates as an Avnet subsidiary rather than an independent firm. Its services span firmware development, embedded Linux implementation, and secure boot, encryption, and OTA update mechanisms, and the Avnet relationship can simplify sourcing when a client also needs component distribution alongside software.
Sigma Software Group
Sigma Software Group was founded in Kharkiv, Ukraine in 2002 by five friends and now employs more than 1,100 people across Ukraine, Sweden, Poland, and the United States. In 2006 the Swedish IT conglomerate Sigma Group acquired a 60% stake in the company, an ownership structure that has held since; the remaining 40% stays with the original Ukrainian founders. Its embedded and IoT services cover application development, firmware, middleware, device drivers, and human-machine interfaces, delivered as one practice within a much larger portfolio spanning gaming, aviation, and telecom software.
