Lemberg Solutions vs Sigma Software Group: overview
Lemberg Solutions
Lemberg Solutions runs its engineering out of Lviv, Ukraine, with additional offices in Hamburg, London, and Kraków, all comfortably within a one-to-two-hour window of UK working hours. Founded in 2007, the roughly 200-person team specializes in firmware, embedded Linux, and electrical engineering, wrapped in a broader Cloud, Data & AI, and Digital practice, so a UK buyer building a connected medical device or industrial IoT platform gets electronics through cloud from one vendor. 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 founded Sigma Software Group in Kharkiv in 2002; the company has since scaled to more than 2,100 professionals across roughly 40 offices worldwide, with its post-2022 expansion adding real Western European delivery presence alongside its original Ukrainian base. Named practices in aerospace, gaming, fintech, and automotive engineering give it a technical-consulting positioning UK buyers evaluating a specific vertical need can lean on. That same expansion means a buyer specifically wanting Ukraine-concentrated delivery should verify current team location directly.
