ARCH-Embedded vs Sigma Software Group: overview

ARCH-Embedded

ARCH-Embedded was founded in Amsterdam in 2022 by CEO and co-founder Mark Riemersma and operates with a team of 2 to 10 people. As a Nordic Semiconductor partner, the firm's stated background is specifically in positioning technology and micro-mobility, with prior team experience at companies like TomTom, and it covers the full stack from hardware through embedded software, RTOS, Linux, security, and connected-device architecture and project management. That positioning-technology specialty is narrow but genuinely differentiated, useful specifically for clients building location-aware or cellular-connected hardware rather than general-purpose embedded products.

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.

ARCH-Embedded vs Sigma Software Group: pros and cons

ARCH-Embedded
+ Nordic Semiconductor partner status backs its cellular and positioning-technology hardware claims
+ Team background in positioning technology at companies like TomTom is a specific, differentiated specialty rather than general IoT experience
+ Full-stack scope from hardware through RTOS, Linux, and security architecture covers more than firmware coding alone
+ Small team size means direct senior engineering involvement on every engagement
- Founded in 2022 with 2 to 10 employees, giving it one of the shortest track records and smallest teams on this list
- Capacity for large or multiple concurrent programs is limited by team size
- No published pricing or minimum engagement figure
Sigma Software Group
+ 1,100-plus employees across Ukraine, Sweden, Poland, and the US give substantial delivery capacity and timezone coverage
+ 60% Swedish ownership since 2006 brings the governance and stability of an established Scandinavian IT conglomerate
+ 23 years of operating history under continuous leadership from its original founding team
+ Multi-industry portfolio spanning aviation, gaming, and telecom means firmware engineers work alongside teams solving comparable real-time and reliability problems in other domains
- Firmware and embedded work is one practice within a much broader multi-industry engineering group, not the company's sole focus
- 60% ownership by Sweden's Sigma Group means the company is not independently controlled by its original Ukrainian founders
- No published pricing or minimum engagement figure
