Efelya is dedicated to the prevention and detection of at-risk pregnancies. There are 35 million at-risk pregnancies worldwide each year. The medical innovation of Efelya is the management of obstetrical risk during pregnancy. It sets up a predictive monitoring of the evolution of the risk thanks to the use of an algorithm associated with a connected "pregnancy passport". If a pathology risk is detected, Efelya sets up monitoring protocols that adapt as soon as medical data is interpreted by the algorithm.
