We are building a multi-sided digital platform which allows both customers (importer/exporter) and operators to efficiently and fluidly process international trade workflows, which are today processed mostly through human labor.

Our platform currently covers freight forwarding and we are aiming to expand our coverage throughout the international trade supply chain.
