Orpheus

Office occupancy analytics and meeting room booking for Outlook and Teams, both driven by sensors that know who is really there. See how your office is really used Space counts people by floor, zone and meeting room, hour by hour, with sensors that record no images. You see live occupancy, the real peak of each day, which floors and rooms sit empty, and CO₂, temperature and noise, with monthly reports ready for leadership. It is the workplace analytics that badge swipes, bookings and Wi-Fi can't give you: on an average day, the offices in our 2026 report peak at 45 % of their desks. Meeting rooms that follow what really happens Meet puts a screen at every room's door, synced with Microsoft 365 (Outlook and Teams) and Google Workspace. With a sensor inside, meetings check in by themselves, bookings nobody shows up for are released after ten minutes (18 % of booked meetings stay empty), a group that walks into a free room gets it booked, a meeting that ends early frees the room, and each invite gets the room that fits its size. At the door, people book on the spot or extend by 15, 30 or 45 minutes. Screen sharing in every room Cast turns the room's screen into wireless screen sharing: plug the USB-C dongle into your laptop and you are on screen or in the video call. While the room is free, the screen shows the day's meetings and your Workplace team's announcements. Also in Orpheus Comfort alerts with a work order in your CMMS, staff canteen occupancy in real time with Cafe, an open API to take the data to your BMS or BI, and an MCP server so Microsoft 365 Copilot, Claude, ChatGPT or Gemini Enterprise can answer questions about your office. No building work and nothing on your network: the sensors connect through our own LTE hub. Our team helps you read the data and act on it. Used by Roche, Bayer, SEAT:CODE and other large companies across Europe, including the UK.
