Who are we?
Founded in Barcelona in 2021, Trialing is on a mission to provide equal access to clinical trials for all patients.
Clinical trials offer a unique opportunity for patients to receive the most innovative treatments available. Our goal is to develop advanced technological tools that empower healthcare professionals to offer these trials to every patient.
We’ve built a powerful search engine that allows doctors to find clinical trials quickly and efficiently. It also enables them to refer patients from one hospital to another. As a result, we help hundreds of patients every day access cutting-edge treatments they might not have otherwise had the chance to receive.
After two years of growth—and with users in over 500 hospitals—we’ve established ourselves as leaders in Southern Europe and are now expanding globally. We’re looking for smart, dedicated individuals who share our vision and want to help us make a meaningful impact on the lives of thousands of patients.
