ITRex Group vs Andersen: 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 generative AI and machine learning with data analytics and cloud computing rather than offering AI in isolation, which means clients get a partner who can handle the data plumbing a generative AI system needs before the model itself gets built. That broader scope costs some depth relative to generative-AI-only specialists but avoids a common integration bottleneck.
Andersen
Andersen was founded in 2007 and lists its headquarters in Warsaw, Poland, with more than 3,500 specialists across 20 office locations and 16 development centers globally. Its named AI and data practice covers generative AI consulting, machine learning, data engineering, and robotic process integration, alongside a broader stack spanning .NET, Java, Python, PHP, and Go. Industries served include financial services, healthcare, logistics, automotive, and media.
