Sigma Software Group vs Developex: overview
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.
Developex
Developex was founded in Kyiv, Ukraine in August 2001 and has grown to approximately 255 employees, with a representative office in Canada supplementing its Eastern European delivery base. Its primary stated service is forming software development teams for mobile, cloud, web, and desktop projects, with a second specialization in software for electronic devices covering firmware, drivers, and companion apps. That ordering matters for buyers: firmware capability exists and is real, but it sits behind a larger cross-platform software practice rather than being the firm's lead identity.
