Boldare vs Sigma Software Group: overview

Boldare

Boldare was founded in Gliwice, Poland in 2004 and has spent two decades building digital products for international clients, organizing itself internally under a holacracy-style, self-managed structure rather than a traditional management hierarchy. That EU headquarters gives UK buyers the same straightforward GDPR posture as its Polish peers, while its unconventional internal structure is a genuine, verifiable differentiator for a buyer curious how the actual delivery team is organized, rather than a marketing phrase.

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.
