| - | $200K+ minimum engagement and premium T&M rates reflect global firm pricing — not accessible for most mid-market buyers |
| - | Engineering-first culture means projects can be slower and more process-heavy than purely outcome-focused boutiques |
| - | Less depth in data science and statistical modelling relative to analytics-native competitors like Tiger Analytics or Fractal |
| EPAM Systems | |
|---|---|
| + | 58,000+ engineers provide unmatched concurrent delivery capacity for large-scale enterprise ML programmes |
