Portfolio Companies and Business Units

Roslin Technologies’ value is created from the successful commercialisation of technologies, starting from small scale seeding projects through to the creation or acquisition of large scale connected and complimentary Business Units or Portfolio Companies. The goal of Roslin Technologies is to build high value in these Ag-Tech Ventures that together deliver attractive returns but also may represent spin off opportunities in future. Below are the entities we have built since our inception in 2016.
