Sigma Software Group vs Railsware: 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.
Railsware
Railsware calls itself a product studio rather than a development agency, and its 2007 founding in Kyiv backs that positioning: the company has built and operated its own SaaS products alongside client work, giving its engineers first-hand experience with product decisions most outsourced teams never see. It now runs offices across Kyiv, Kraków, Warsaw, and West Hollywood, covering MVP development, product strategy, and AI/ML work. That product-ownership background is a genuine differentiator for an early-stage founder who needs a partner that actually thinks about product-market fit, beyond ticket completion.
