PatientsLikeMe is a platform, founded in 2004, where patients can share and learn from patient-reported health data. Its objective is to transform the way patients manage their own conditions, change the way industry conducts research and improve the way patient care is delivered. As of March 2015, it had 300,000 members representing 2300+ conditions. PatientsLikeMe helps companies better understand the real world medical value of their products and has the potential to accelerate the development of new solutions for patients.
