The future circular electron-positron collider (FCCee) is strongly supported by CERN as the next large collider. We present the main requirements for a detector at FCCee and the technical solutions chosen to address them; in particular an example of a detector concept optimized for FCCee, IDEA, is presented. We then outline related detector R&D activities currently in progress and identify several areas of potential collaboration.
