eSparkBiz vs Belitsoft: overview
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.
Belitsoft
Belitsoft was founded in 2004 and is headquartered in Warsaw, Poland, with over 250 core employees and more than 400 developers, testers, project managers, and DevOps staff distributed across Poland, Latvia, and Georgia. The company expanded into cloud and AI development in 2024, layering AI software solutions on top of an already-established web and mobile development and team augmentation business. That makes AI a genuinely recent addition rather than a rebrand of older services.
