+ 500–1,000 employees across six locations provides substantial delivery capacity for multi-workstream programs.
+ 15 years of company history (since 2009) with demonstrated growth from founding to enterprise-scale headcount.
+ Custom LLM development is a specifically named, differentiated service rather than generic "AI consulting."

Andersen
