- Small team size of 11 to 50 limits capacity for large, multi-workstream programmes
- Less suited to heavily regulated enterprise ML programmes than larger specialist firms
Siili Solutions
+ Publicly listed on Nasdaq Helsinki, providing financial transparency and stability signals
+ Two decades of operating history since founding in 2005, with a large, established Nordic footprint
+ 19 office locations support broad European coverage and delivery flexibility
+ Expanded AI and digital product capability via its 2020 acquisition of Supercharge in Budapest
- AI and ML is one practice within a much broader generalist IT consultancy portfolio
- 2020 acquisition of Supercharge represents a group ownership change worth understanding before engaging that subsidiary specifically
- Larger public-company structure may mean less flexibility than privately held boutiques
