Choosing the Right Parking Operator Matters

Not all operators are built the same. Here’s how our approach compares so you can choose the partner that truly aligns with your goals.

Their Approach

Diamond Parking is well-established regionally and they bring a traditional approach to parking management, often relying on third-party technology and hardware for operations. Locations under Diamond parking management may use equipment and services from providers like ParkMobile, Arrive (ParkWhiz), and T2 Systems to handle mobile reservations and payments. They offer some unique customer care options for drivers in their lots, including free locksmiths or emergency fuel. However, their fragmented and service-oriented approach to parking solutions doesn’t offer an integrated, technology-based parking system that can reliably and sustainably improve revenue performance.

Our Approach

AirGarage takes a modern, full-stack approach to parking management—combining technology, operations, and customer service into a seamless solution.

Instead of simply overseeing a property, we actively manage it to maximize revenue, improve the driver experience, and reduce headaches for owners.

Our model is transparent and aligned: we only succeed when you do.

That means no hidden fees, no hands-off oversight, and no outdated systems. Just real-time data, responsive support, and a commitment to keeping your property clean, safe, and profitable.
