Our Expertise

Our open technologies practice is likely the largest in Finland. It is typical that business models for those using open technologies differ from closed technology models. Our thorough understanding and experience of collaboration models, open business models, communities and technology helps us advise our clients effectively and in a result-oriented way. This practice covers open source software, open data, open interfaces, open innovation and collaboration models between companies and organisations

We advise our customers for example in

  • use and publication of open source, open data and open interfaces
  • in procurements and participation into procurements related to open technologies
  • implementation of business models,
  • creation of open source policies and
  • in setting up collaboration models, negotiations and governance (also in relation to the Association Act).
