Grid Dynamics vs Belitsoft: overview

Grid Dynamics

Grid Dynamics (Nasdaq: GDYN) is a publicly traded digital engineering company founded in Silicon Valley in 2006, now headquartered in San Ramon, California with roughly 5,000 technical professionals across 19 countries. Its AI services group explicitly markets generative, agentic, and physical AI alongside its longer-standing data platform and cloud-native engineering practices, giving it public-company financial transparency that most firms on this list lack. Agentic AI is one line of business within a much broader digital-engineering portfolio, rather than the firm's sole focus.

Belitsoft

Belitsoft is a custom software development company founded in 2004 with headquarters in Warsaw, Poland and delivery teams distributed across Poland, Latvia, and Georgia, totaling roughly 130–400 developers, testers, and other specialists depending on the source. It serves industries including e-learning, healthcare, fintech, and — more recently — artificial intelligence and agent development. Reported employee counts vary significantly by source, so buyers should confirm current team size directly before committing to a large program.
