Sigma Software pros and cons
| Advantages | Things to consider |
|---|---|
| +2,100+ professionals across 40 offices in 19 countries give exceptional scale and geographic reach | -Legal HQ (Stockholm) is a corporate and ownership structure rather than the company's historical engineering center of gravity (Kharkiv, Ukraine) — buyers should understand this distinction |
| +Majority Swedish ownership (Sigma AB, 60%) since 2006 provides a stable, publicly documented corporate structure | -2,100+ person, 19-country scale means AI/ML is one capability among many broad IT consultancy services, not a named specialist practice |
| +Founded 2002 by five Kharkiv co-founders — over two decades of continuous operation | -Public information on a dedicated AI/ML practice or named AI case studies is less detailed than several boutique competitors on this list |
| +40-office footprint across 19 countries supports very large, multi-region enterprise programs |
