The ranking, in detail
01
Software engineering teams staffed offshore and nearshore
A global leader in software engineering and digital platform creation, serving Fortune 500 companies across multiple industries.
Best for: Enterprises staffing multi-year engineering and managed-service programmes across nearshore and offshore locations, at team scale rather than one or two contractors.
PROS- Delivery scale is large and published: approximately 56,650 delivery professionals as of 30 June 2026, including about 12,200 in India, 8,750 in Ukraine and 5,050 in Poland at 31 December 2025.
- Client relationships tend to run long, which matters for managed services: EPAM reports 64.4% of 2025 revenue came from clients of at least five years' standing and 35.7% from clients of ten years or more.
CONS- About a fifth of delivery staff sit in Ukraine and Belarus (roughly 8,750 and 3,400 at 31 December 2025), and EPAM's annual report states the war in Ukraine has had and could continue to have a material adverse effect on its operations, so buyers with strict continuity requirements need delivery locations written into the contract.
