Open Technologies

Our Open Technologies practice is likely the largest in Finland. Our thorough understanding and experience of open collaboration and business models as well as open communities and technology helps us in advising our clients effectively and in a result-oriented way.

  • procurements, and participation in procurements, related to open technologies
  • the implementation of business models
  • creation of open source policies and other open source compliance
