Belitsoft vs ITRex Group: overview
Belitsoft
Belitsoft was founded in 2004 and is headquartered in Warsaw, Poland, an EU member state, with over 250 core employees and more than 400 developers, testers, and DevOps staff distributed across Poland, Latvia, and Georgia. The company expanded into cloud and AI development in 2024, layering AI solutions on top of an already-established web and mobile development and team augmentation business. Two of its three delivery countries (Poland, Latvia) sit inside the EU, which matters for clients weighing data residency across the delivery footprint.
ITRex Group
ITRex has been based in Southern California since 2009, with public headcount estimates ranging from around 221 up to over 250 employees across three continents. The agency pairs AI and machine learning with data analytics and cloud computing, though its published delivery footprint centers on North America rather than Europe, which European buyers should factor into any data-residency planning.
