The document summarizes LightFi, a startup developing an occupancy and environmental sensor for buildings. It monitors occupancy, temperature, lighting and CO2 levels to optimize HVAC and lighting systems. The sensor installs in 10 minutes without rewiring and provides insights and energy savings of 57% and 40% respectively. It has a 1 year ROI. The founders have physics backgrounds and experience in digital disruption and entrepreneurship. LightFi is targeting the smart buildings market worth $61B by 2023 and has pilots underway to scale, including with energy utilities and lighting control partners focused on the university market.
