+ Combines cloud-native and AI/ML engineering under one roof, reducing multi-vendor coordination for large programs.
- At ~4,500 employees, engagements are structured around managed delivery teams rather than boutique-style founder involvement.

+ 15 years of company history (since 2009) with demonstrated growth from founding to enterprise-scale headcount.
