+ Full software ecosystem delivery: APIs, data pipelines, model serving, and frontend in one team
+ Strong EU client base with GDPR-compliant delivery frameworks
+ 600+ engineer scale enables large dedicated ML team staffing for multi-year programmes
- $50K minimum excludes smaller ML projects and startups at early stages
- Less hardware AI, edge inference, or embedded ML depth than firms with hardware backgrounds
- Python specialisation means less flexibility for projects requiring Scala, Java, or other ML-adjacent stacks

+ AI-native engineering practice purpose-built for scaling ML, GenAI, and agentic systems
+ Strict governance and compliance frameworks for regulated enterprise AI delivery
+ Full-stack capability from hardware infrastructure through ML models to frontend AI products
+ Strong US and Eastern European delivery mix for cost-performance balance at enterprise scale
- ~$200K+ minimum makes EPAM inaccessible for all but the largest enterprise budgets
- Large-firm overhead — procurement, contracting, and ramp-up timelines are significantly longer than boutiques
- Generalist breadth means less niche ML depth than boutiques in specific domains like healthcare imaging or time-series
