Sigma Software Group vs MobiDev: overview

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.

MobiDev

Mobile apps with a real applied AI or computer vision component are what MobiDev actually specializes in building, out of R&D centers in Poland and Ukraine under a company incorporated in both the US and UK since 2009. Its case studies show genuine computer vision and mobile engineering work for startups and mid-size product companies, going well beyond generic app development. The dual-country R&D structure spreads delivery risk, but Ukraine here is a development location rather than the company's legal home.
