BCG X vs Belitsoft: overview

BCG X

BCG X launched in 2014 as Boston Consulting Group's technology build-and-design division, and it now runs over 3,000 technologists, data scientists, engineers, and designers across more than 80 cities worldwide. The distinction from a typical strategy-house AI practice is deliberate: BCG X is structured specifically to ship the generative AI and machine learning systems it recommends, not just hand off a roadmap and step away.

Belitsoft

Belitsoft was founded in 2004 and is headquartered in Warsaw, Poland, with over 250 core employees and more than 400 developers, testers, project managers, and DevOps staff distributed across Poland, Latvia, and Georgia. The company expanded into cloud and AI development in 2024, layering AI advisory on top of an already-established web and mobile development and team augmentation business, a genuinely recent addition rather than a rebrand of older services.
