OpenXcell
OpenXcell was founded in 2009 by Jayneel Patel and is headquartered in Ahmedabad, India, growing to a workforce of 500–1,000 employees across six locations serving markets in Asia and North America. The company's service portfolio spans AI strategy, custom LLM development, web and mobile development, data engineering, and blockchain, with more than 1,000 delivered solutions reported. Its broad multi-service portfolio positions it as a large generalist IT consultancy with AI as one of several core offerings rather than a pure-play AI specialist.
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.
