R2A Labs is a young deep-tech start-up dedicated to accelerating the development of circular materials. We recently closed our first fundraise and are backed by a lead angel fund in the UK as well as Bocconi University in Italy. Converting complex bio-feedstocks into advanced materials remains a fundamental challenge. Industrial R&D in this space is still heavily dependent on time-intensive physical experimentation, with a lack of robust digital tools to accelerate discovery and enable the development of high-performing bio-based materials at costs competitive with synthetic incumbents. Our proprietary Lab-in-Loop Engine addresses this by tightly integrating digital exploration with physical validation. We use active learning frameworks to continuously feed experimental results back into the model, creating a closed-loop workflow that connects molecular design, process conditions, and material performance into a single pipeline. The founding R2A team combines top technical expertise (PhD Chemistry from Cambridge University, and Marie Curie Fellow at Politecnico di Milano) with commercial excellence (successful repeat entrepreneur). We are rapidly growing, and looking for highly talented individuals to join us in the call to create sustainable alternatives to fossil-based ingredients and in building a post-petroleum future!
