Kalyzée builds the infrastructure that lets a university or a higher-education institution teach the same course in several rooms at once. THE PROBLEM Institutions are asked to open new sites, keep small specialities alive and share scarce faculty — with a generalist video-conferencing tool that was never designed for a classroom. The lecturer ends up operating the technology instead of teaching, and the students on the other end quietly drop out of the session. WHAT WE BUILD A complete comodal room — PTZ cameras, ceiling microphones, screens, a dedicated machine, automated orchestration of the video and audio streams — and Kalyzée Connect, the platform that records, streams, stores and publishes every session, integrated with the LMS, the SSO and the timetable. The room is ready because the class is on the schedule: nobody organises a meeting, nobody points a camera. Three configurations, depending on how the institution teaches: hybrid room (one main room plus remote students), multi-campus (rooms interconnected in real time) and immersive room (a wall of screens so distant students are present in the room). HOW WE DELIVER Hardware, platform and services in one contract: project management, installation, configuration, acceptance testing, teacher training, and N1/N2/N3 support with an SLA. Predictable CAPEX, predictable OPEX, no per-use variable. WHERE IT RUNS From a single 400-student school to a 30-site network serving 23,000 students, an architecture school in Paris with 1,000 students, and a territorial programme opening up access to teaching in French Guiana. Based at 17 La Canebière, Marseille.
