Innowise Group vs Belitsoft: overview

Innowise Group

Innowise, founded in 2007 by three engineers including CEO Pavel Arlou, is based in Warsaw with public headcount estimates ranging from roughly 2,100 to over 3,500. Its generative AI service list covers AI agents, GPT-based systems, computer vision, and NLP document processing, drawn from a total delivered-project base of over 1,300 engagements across 60-plus countries. That breadth trades depth in any single area for coverage across nearly every current generative AI use case.

Belitsoft

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