The case of Comitas Comunicaciones is a clear example of corporate entrepreneurship in the telecommunications sector. This firm was founded to offer telecommunications services in general and telecommunications services applied to telemedicine in particular. Comitas exploits business opportunities in the health care sector that no other firm is currently focusing on adequately. As the case develops, the technical and market difficulties that the firm has faced will become apparent. The role of the incubator firm is particularly important in this case, since it has provided Comitas with resources, capabilities, and technological knowledge that are complementary in the firm’s new activity: information and communications technologies services (ICT) to support telemedicine.
