Start.cat is a development studio in Alella (Barcelona) that has been building custom mobile apps, websites and AI automation since 2012 for demanding companies and institutions. Our speciality is health and research apps. For the Hospital del Mar Research Institute we built Cohorte ARCA, a monthly follow-up app for children and teenagers with asthma, and Your Decision, which helps prostate cancer patients choose a treatment with their medical team (a project with AECC). For Hôpital Robert-Debré in Paris we built D2M, a protein calculator for inherited metabolic disease diets. We also work for brands: loyalty apps such as Club RUBI and product catalogues such as Compo Expert's. What we do: • Native and hybrid mobile apps for iOS and Android, from architecture to store release. • Websites, platforms and admin portals. • Practical AI for SMEs: assistants over your documents, document processing, chat and voice bots, and AI inside existing products. The same small senior team looks after your project from start to finish, with privacy (GDPR) designed in from day one. Have a project in mind? Get in touch at start.cat.
