Envoy launched in 2013 with the promise of bringing visitor management for individual companies into the modern age. When the pandemic hit, it quickly pivoted to control who could come into an office based on factors like local regulations, their state of health and vaccination status.

Today, the company announced the next step in the system, an interconnected building management system for all the tenants in a high-rise building. The ultimate goal is developing an entire building management platform, one where at some point, customers can build add-ons and customizations on top of the existing software.
