| - | Founded 2018 — a relatively short track record compared to Polish and Romanian peers on this list |
| Sigma Software | |

| + | Majority Swedish ownership (Sigma AB, 60%) since 2006 provides a stable, publicly documented corporate structure |
| + | Founded 2002 by five Kharkiv co-founders — over two decades of continuous operation |
