Lemberg Solutions vs Sigma Software Group: overview
Lemberg Solutions
Next to the giants on this list, Lemberg Solutions is a small company: roughly 200 engineers, founded in Lviv in 2007, with additional offices in Hamburg, London, and Kraków. What it offers instead of scale is depth in one area most generalist outsourcing giants don't staff for: embedded systems, firmware, electrical engineering, and hardware-adjacent product work, wrapped in a broader Cloud, Data & AI, and Digital practice. Clients include Astronics, Caltech, Ferno, Cellink, and Bosch Rexroth, backed by ISO 27001 and ISO 9001 certification and direct partnership tiers with NXP, STMicroelectronics, and Microchip.
Sigma Software Group
Sigma Software Group's roughly 40-office footprint today is a long way from where it started: a single office in Kharkiv, opened in 2002 by five friends, four programmers and a lawyer. More than 2,100 professionals now work across named practices in aerospace, gaming, fintech, and automotive engineering, giving it a technical-consulting positioning closer to the mid-market global firms on this list than to a pure staffing vendor. Its post-2022 global expansion has genuinely diversified delivery risk away from any single country, though a buyer specifically wanting Ukraine-concentrated delivery should verify current team location directly.
