Lemberg Solutions vs Sigma Software Group: overview
Lemberg Solutions
Lemberg Solutions has operated out of Lviv, Ukraine since 2007 and has grown to more than 200 engineers across offices in Lviv, Hamburg, London, and Kraków. Its core strength sits in embedded systems: firmware, RTOS and embedded Linux development, FPGA programming, and electrical engineering, backed by an in-house hardware lab with oscilloscopes, evaluation kits, and HIL testing rigs. That embedded depth is wrapped in a broader Cloud, Data & AI, and Digital practice, so a client building a connected medical device or an industrial IoT platform can get the electronics, firmware, and cloud backend from a single vendor instead of coordinating three separate ones. Clients include Astronics, Caltech, Ferno, Cellink, and Bosch Rexroth, and the company holds ISO 27001 and ISO 9001 certification alongside direct partnership tiers with NXP, STMicroelectronics, and Microchip.
Sigma Software Group
Five friends started Sigma Software Group in Kharkiv in 2002; the company now runs roughly 40 offices across 19 countries with more than 2,100 professionals. It runs practices across gaming, aerospace, fintech, and automotive engineering, positioning itself as a technology consulting and product development partner rather than a pure staffing vendor. The company's own relocation and expansion since the 2022 full-scale invasion has moved a meaningful share of delivery capacity outside Ukraine, which buyers who specifically want Ukraine-based delivery should confirm directly.

Lemberg Solutions vs Sigma Software Group: pros and cons
| Lemberg Solutions | |
|---|---|
| + | Full-stack engineering from electronics and firmware through cloud and AI, useful for hardware-adjacent products that would otherwise need multiple vendors. |
| + | Direct partnership tiers with NXP, STMicroelectronics, and Microchip rather than working purely from public documentation. |
| + | ISO 27001 and ISO 9001 certification, plus healthcare-specific work under IEC 62304 and FDA 21 CFR Part 820 requirements. |
| + | In-house hardware lab shortens the iteration loop on board bring-up and HIL testing instead of shipping hardware out to a third party. |
| + | Full intellectual property and source code transfer to the client on every engagement. |
| - | Not the right fit for a buyer who only needs a plain web or mobile app with no hardware, embedded, or deep-technical component |
| - | Does not run mass production in-house; supports development and ongoing maintenance, but the client still needs a separate manufacturing partner |
| - | Does not obtain regulatory certification on the client's behalf; provides the technical documentation and engineering support, but the client or a third party owns the approval process |
| Sigma Software Group | |
|---|---|
| + | Broad geographic footprint reduces single-country delivery risk compared with Ukraine-only vendors. |
| + | Named practices in aerospace and gaming that go beyond generic full-stack development. |
| + | Founder-led history stretching back to 2002, with the original founders still visible in public communications. |
| - | Global office expansion means Ukraine-specific delivery capacity is not guaranteed for every engagement; confirm team location before signing |
| - | Broad multi-industry positioning can make it harder to judge depth in any one niche compared with a narrower specialist |
