ITRex Group vs eSparkBiz: 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.
eSparkBiz
eSparkBiz was founded in 2010 and is headquartered in Ahmedabad, India, holding CMMI Level 3 and ISO 9001:2008 certifications. Reported staff counts vary considerably, from roughly 63 employees in one tracker up to a LinkedIn-listed range of 201-500, a gap the company attributes to distinct US and India entities operating under a shared brand. The firm describes more than 300 trained software engineers overall and delivers AI as part of a broader IT services and consulting practice rather than as a standalone specialty.
