  • Knowledgeable and experienced. One of the top-level firms in Estonia with industry-standard capabilities and solutions.
  • Our main contacts at Sorainen are Kätlin Krisak, Kamilla Alma Vilderson, and Hetti Lump-Kivisaari. We value our relationship with them highly and can attest to the very high level of professionalism displayed throughout the years we have had the privilege to cooperate with them. One major aspect that I would like to highlight is the fact that they have seemingly effortlessly met and kept up with our internal deadlines, which sometimes may be quite tight. We look forward to continuing to work with them on current matters and projects we have in development.
