Deloitte vs EPAM Systems: overview
Deloitte
Deloitte is the largest of the Big Four by revenue, founded in 1845 in London, with over 470,000 people and $70.5 billion in FY2025 revenue. It has committed more than $3 billion to generative AI through FY2030 and launched Zora AI, its agentic product line built with NVIDIA, plus a global network of agent products built on partner platforms. For integration buyers, its value lies in regulated industries where audit, risk, and controls work happens next to the technology. It's rarely the cheapest or fastest route to a single working workflow.
EPAM Systems
EPAM Systems was founded in 1993 and is headquartered in Newtown, Pennsylvania, with over 61,200 employees at the end of 2025. Acquisitions shaped the recent mix: NEORIS (2024) for Latin America and Iberia, and First Derivative (completed December 2024) for financial-services data. Management targets more than $600 million of AI-native revenue in 2026, after reporting over $105 million in Q4 2025. Its AI/Run tooling and Agentic QA product support large engineering programs more than single-workflow pilots.
