Cortex is built to dramatically improve how buildings operate by applying software and analytics to highly underutilized data streams. By building the software and analytics layer overtop these disparate data streams, we can fundamentally improve the sustainability of commercial buildings, the value of those assets, and the experience of occupants inside them.
