Konstant Infosolutions vs Belitsoft: overview
Konstant Infosolutions
Konstant Infosolutions was founded in 2003 and has grown from a two-person operation to roughly 180 tech experts, with offices in the United States and UAE serving clients across Canada, the UK, Saudi Arabia, and other regions. The firm's AI/ML offerings include product design and development, AI consultancy, integrations, and strategy planning, spanning AI/ML, generative AI, AI chatbots, computer vision, and predictive analytics, and it holds more than 175 reviews on Clutch. Its core identity as a mobile/web app development company means AI/ML is a newer, extended capability rather than a founding specialty.
Belitsoft
Belitsoft has operated since 2004 and is headquartered in Warsaw, Poland, with more than 400 software developers, testers, project managers, and DevOps staff distributed between Poland, Latvia, and Georgia. The firm's AI/ML specialists design, train, and fine-tune models, while its software engineers integrate those models into client products; for enterprise and Fortune 500 clients, Belitsoft supplies larger teams including data engineers and MLOps engineers for deployment and monitoring. Its core strength — 20+ years of SaaS development experience — makes it a strong integration partner, though its AI-specific brand recognition is thinner than firms that were AI-native from founding.
