Portfolio highlights

• Prosoma — Prosoma was born out a need to provide more comprehensive care for cancer patients. We have found a fundamental lack of access to psychological care for patients who not only have to face a life-altering disease and treatment, but also crucially have a different set of needs than other psychological patients. Barriers to accessing psychologicalcare often include low numbers of therapists and clinicians in the area, financial or geographical limitations, and the general wellbeing of patients preventing them from attending meetings. All of these issues can be solved by modern technology.By using VR as part of, or when necessary, an alternative to traditional psychological treatment, we can reach patients that would otherwise be left without any support. They can use our tool at home or in the clinics whilst undergoing pharmacological treatment and chemotherapy.We hope to provide patients with a tool that will help them manage stress, cope with the burden of cancer, and eventually improve their quality of life.
