Eliko was created over 10 years ago by the Estonian software and electronics industry and the Tallinn University of Technology. We have since published numerous pieces of original research, acquired patents and developed innovative products for our clients.

Eliko’s core competence is in the Internet of Things (IoT) related technologies. A third industrial IoT research and development program was started in 2015 to help companies develop a strategic view on IoT and design future-proof products and services for the connected world.
