Emcraft Systems vs Sigma Software Group: overview

Emcraft Systems

Emcraft Systems is headquartered in Carlsbad, California and builds production-ready system-on-modules around ARM Cortex-M microcontrollers and Cortex-A microprocessors, alongside the Linux and RTOS board support packages that run on them. The company maintains its own BSPs rather than relying solely on a chip vendor's reference package, which gives it long-term update responsibility for the firmware layer under a client's application code. It holds STMicroelectronics partner status, and its board-plus-BSP model suits companies that want a hardware module and a maintained firmware base together instead of sourcing them separately.

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.

Emcraft Systems vs Sigma Software Group: pros and cons

Emcraft Systems
+ Self-maintained BSPs give long-term update ownership rather than depending on a chip vendor's reference package alone
+ STMicroelectronics partner status backs its ARM Cortex-M and Cortex-A module line with direct chip-vendor support
+ Combining hardware modules with firmware support removes a sourcing step for companies that would otherwise need two vendors
+ Focus on both Linux and RTOS BSPs covers a wider range of real-time requirements than a Linux-only board vendor
- Public founding year and team size figures are thin, and the company's own materials don't publish a founding date directly
- Its business model centers on selling its own hardware modules, which is a narrower fit for a client who has already committed to different silicon
- 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
