Our Story

GuestOf was created by two college friends in February of 2016 after getting stuck waiting outside of apartment complexes one too many times. Since then, we've expanded our mission to focus on providing easy to integrate physical access & identity as a service to businesses and applications of all kinds.  We're always looking for feedback and would love to hear from you, so feel free to shoot us an email at info@guestofapp.com.
