Lemberg Solutions vs Sigma Software Group: overview
Lemberg Solutions
Firmware, embedded Linux, and FPGA programming are what Lemberg Solutions actually builds most of the time, a different core skill set than the web and mobile development most companies on this list specialize in. The Lviv-founded company, running since 2007, has grown to more than 200 engineers across offices in Lviv, Hamburg, London, and Kraków, and wraps that embedded depth in a broader Cloud, Data & AI, and Digital practice. Clients span 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, four programmers and a lawyer, started Sigma Software Group in Kharkiv in 2002. More than two decades later the company runs roughly 40 offices across 19 countries with over 2,100 engineers, building software for aerospace, gaming, fintech, and automotive clients under named domain practices rather than one generic development service. Its post-2022 expansion has shifted a real share of delivery capacity outside Ukraine, so a buyer who specifically wants Ukraine-based engineers should confirm current team location.

Lemberg Solutions vs Sigma Software Group: pros and cons
| Lemberg Solutions | |
|---|---|
| + | Genuine embedded and firmware engineering depth, a specialty most general software development companies on this list don't have. |
| + | 360° coverage from electronics through cloud and AI means one vendor instead of three for a hardware-adjacent product. |
| + | ISO 27001 and ISO 9001 certification, plus healthcare-specific delivery under IEC 62304 and FDA 21 CFR Part 820. |
| + | Direct partnership tiers with NXP, STMicroelectronics, and Microchip, beyond public-documentation-level familiarity. |
| + | Full intellectual property and source code transfer on every engagement. |
| - | Narrower fit for a buyer who just wants a standard web or mobile application with no hardware or embedded component |
| - | Does not run mass production in-house, only development and ongoing maintenance |
| - | Does not obtain regulatory certification on the client's behalf, only the technical documentation to support it |
| Sigma Software Group | |
|---|---|
| + | Named engineering practices in aerospace and gaming, both genuinely rare specialties. |
| + | Global office footprint spreads delivery risk across 19 countries. |
| + | Founder-led history stretching back to 2002. |
| - | Post-2022 global expansion means Ukraine-based delivery is not guaranteed for every team; confirm before signing |
| - | Broad multi-industry positioning makes single-niche depth harder to verify at a glance |
