The story behind R8 Technologies

Co-founder Siim Täkker was previously working on building energy simulations and optimisation algorithms at a scientific engineering level.

In 2016 Täkker began working for one of the biggest building servicing companies in Estonia, observing huge savings potential if they altered the way they operated.

Together with friends, they developed an HVAC optimization platform that could be integrated into any building and would make its automation systems independent.

With proper data analysis, they discovered that there were countless faults within building HVAC systems that were not solved or remained unseen. It was evident that there was an urgent need for improvement in the field.

R8 Technologies was born.

Built in the Baltic Silicon Valley

R8 Technologies originates from Estonia, a small country located in North-East Europe, known the world over as the Baltic Silicon Valley due to it’s leading digital and technologies.

The home of ​Skype​, Estonia has built its core reputation on sound technological platforms with first-class digitalisation like no other.
