CircularTree was founded in 2018 and is based in Berlin.
Our goal is to provide solutions for supply chains to become more responsible and sustainable.
With Blockchain technology, supply chain challenges such as lack of trust, transparency, and traceability are minimized and inefficiencies are eliminated.
We work on different projects within various industries and collaborate with global operating entities.

Compliance Interoperability

Makes it easier for everyone to manage their responsibilities in the supply chain. CircularTree is building a collaborative blockchain-powered ecosystem for organizations to contribute, share, and leverage compliance information.


Trusted Cross Enterprise Workflows
