ITRex Group vs Intellectsoft: overview

ITRex Group

ITRex was founded in 2009 and operates out of Southern California, with public employee counts ranging from about 221 to 250-plus across three continents depending on the source. The firm works across artificial intelligence, data analytics, and cloud computing for enterprise clients rather than treating AI as a standalone product line, which shows up in how its case studies mix AI delivery with broader data infrastructure work. That breadth is a trade-off: buyers get a partner comfortable with the surrounding data plumbing an AI system needs, not just the model itself.

Intellectsoft

Intellectsoft was founded in 2007 by Alexey Kharchykov and Dmitriy Kulikov in Kyiv, and public sources list headquarters variously in New York and Palo Alto today. Employee estimates range from about 51-200 on LinkedIn to 200-300 on other trackers, with the company describing 150-plus engineers across 10 offices. Its practice spans custom software development, AI, blockchain, and cloud computing for enterprise, SMB, and startup clients, giving it broad but not deeply specialized AI coverage.
