After 25 years of business, Tina Urquhart is responsible for concierge services covering 45 million square feet of space in 350 buildings, just in the DMV.

Starting with services like laundry and car valet in 1993, Urquhart built Charm City Concierge into a full-service concierge and experience management firm. Now she’s adding technology to that list with the release of its new mobile app, Simpli.

Launched in May, Simpli allows tenants to use building amenities, reserve spaces, find events and otherwise improve their experience at work or in large residential properties. Property owners can track which amenities are used most and get feedback from tenants through the app.
