About Us


9 years on research and development of Ultrasound Technology and 4 on BlockChain Solutions


Today we are better at doing what we do than we were yesterday. So we keep doing it for a better tomorrow.


Even if we know it works, nothing better comes out of doing the same. No fear of new things. No fear of failure.

We’re A Software Production Company.

Since 2013, we have come a long way with COPSONIC to creare a solid solution that allows to cover over 100 use cases for sonic/ultrasonic data transmission. In 2019 we built a blockchain-based gold tokenization system integrated with ultrasonic technology via a custom hardware wallet. We did not look back. Since 2021 in cooperation with Visioblock we have been working on a stable cryptocurrency to revolutionize the reward and engagement industry.
