DS Stream vs EPAM Systems: overview
DS Stream
DS Stream was founded in Warsaw in 2017 and has between 150 and 200 engineers, with a US entity in Delaware. Its LLMOps offer bundles an evaluation harness, prompt versioning, guardrails, observability, and routing across several model providers. The company says clients see measurable impact in six to ten weeks on AWS, Google Cloud, or Azure (per company website; independently unverifiable). Data engineering is its other main line, which helps when the real blocker is the data feeding the model.
EPAM Systems
EPAM Systems was founded in 1993, is headquartered in Newtown, Pennsylvania, and employs more than 61,000 people. It bought NEORIS and First Derivative in recent years to expand in Latin America and financial services. Its AI work sits inside a large software engineering business, so production AI usually arrives as part of a broader platform or product program. That suits enterprises with many products more than a company with one stalled pilot.
