ParkWhiz is an e-parking service that allows users to book a guaranteed parking space before reaching their destination. In addition to its consumer-focused parking solutions, ParkWhiz creates software to help parking owners manage and market their parking using the ParkWhiz website, mobile apps, and data APIs. ParkWhiz was launched in Chicago, Illinois where its headquarters remain today. ParkWhiz was founded in 2006 by Aashish Dalal (current CEO) and Jon Thornton. With its origins in Chicago at a few parking facilities around sporting events, ParkWhiz has grown from a bootstrapped venture to a service that works with 4,000 parking facilities in over 50 major cities and 35 states. Founders Dalal and Thornton conceived of the ParkWhiz concept in 2004 after becoming frustrated with the problem of locating parking during baseball games. While parking spaces were available at various parking facilities, there was no organized system for determining their location or their price.
