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 modernizing building access with a keyless, easily retrofitted entry solution for apartment complexes, office buildings, Airbnb offerings, and more.  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.

You can find us at NextFab, a prototyping/co-working space in southwest Philly.  If we're not on the second floor, we're probably doing our best not to break any of the metalworking equipment downstairs (sorry Matt W).
