Your future Company

Circularise is a supply chain traceability start-up founded in The Netherlands in 2016. We believe that end-to-end traceability holds the key to overcoming major challenges that society faces in areas such as Circular Economy, Environmental Pollution and Carbon Emissions. Therefore, it’s our mission to bring traceability to global supply chains and to accelerate the world’s transition to a Circular Economy.

Circularise is disrupting industries by changing how companies trace their products and materials and share information about them, enabling sustainable practices at an unprecedented level. We achieve that with a blockchain-based open protocol that enables sharing of information about products and materials while retaining privacy over sensitive information.
