SoftServe vs XenonStack: overview

SoftServe

SoftServe was founded in 1993 and is legally headquartered in Austin, TX, with primary delivery centres in Ukraine and Poland (approximately 10,000 engineers total). The firm has built a dedicated generative AI practice with particular depth in healthcare: named case studies include clinical workflow automation and document extraction for major health systems. SoftServe holds Azure Solution Partner and AWS Partner credentials. Like EPAM, AI is one practice within a large full-services portfolio, which gives it delivery scale but dilutes specialist agentic focus. For buyers who need GenAI integrated alongside broader IT services — especially in healthcare — SoftServe is a competitive option to EPAM at somewhat lower minimum thresholds.

XenonStack

XenonStack is a technology consulting company founded in 2016 and headquartered in Mohali, India, specialising in platform engineering, real-time analytics, generative AI, and observability. The firm builds agentic AI systems alongside its data and cloud engineering practice, serving enterprise clients in North America, Europe, and Asia. XenonStack's AI agent work is grounded in its platform engineering depth, making it a strong fit for companies that need AI agents to operate reliably within large-scale, cloud-native infrastructure.
