ITRex Group vs eSparkBiz: overview
ITRex Group
ITRex has been based in Southern California since 2009, and public headcount estimates range from around 221 up to over 250 employees across three continents. The agency pairs artificial intelligence work with data analytics and cloud computing rather than offering AI in isolation, which means clients get a partner who can handle the data plumbing an AI system needs before the model itself gets built. That broader scope costs some depth relative to AI-only specialists but avoids a common integration bottleneck.
eSparkBiz
eSparkBiz was founded in 2010 in Ahmedabad, India, and holds 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 under a shared brand. The agency describes more than 300 trained engineers overall and delivers AI as part of a broader IT services and consulting practice rather than as a standalone specialty.
