What Interstate Parking does
Interstate Parking, LLC is a privately held parking management operator headquartered in Milwaukee, Wisconsin, running 100+ parking facilities across 8 cities in 5 states (Wisconsin, Minnesota, North Dakota, Indiana, Colorado). The company serves two primary customer sets: individual drivers purchasing hourly, daily, monthly, or prepaid-session parking, and commercial/municipal property owners contracting for full-service parking asset management. Consumer offerings are structured in three tiers — Monthly Unlimited subscriptions (ParkingBase-backed with reserved spaces and auto-pay), Flex Park prepaid session packs (HonkMobile-integrated for 2-3 days/week users), and Single Day Parking (pay-as-you-go via TapNPark and direct channels) — supported by SMS short-code payment (94201), license-plate recognition at select California sites, and citation processing portals across six markets. On the enterprise side, Interstate Parking provides Property Acquisition, Development Financing, Guaranteed Lease, At-Risk Management, and Technology/Operational Design Consulting, backed by a minimum 10% profit increase guarantee and 100% customer service resolution guarantee in the first twelve months of engagement. Venue partnerships with major sports and entertainment assets (Fiserv Forum, US Bank Stadium, Xcel Energy Center, Wisconsin State Fair Park, Target Center/Field, Pabst Theater, Riverside Theater) anchor event-day demand, while municipal engagements (City of Excelsior, Milwaukee County Courthouse) extend into government services. The company is locally owned and operated in each market with on-the-ground operating partners, positions 24/7 senior management availability as a differentiator, and was recognized as a 2023-2024 Top Workplace. Technology is delivered primarily through partnerships — Inflow, Inc. powers the consumer application platform; HonkMobile, TapNPark, ParkingBase, and SpotHero handle mobile access, subscription management, and marketplace distribution. No external funding rounds, institutional investors, or parent company relationships are disclosed.

- LAZ Parking: Privately held, multi-market parking management company operating thousands of facilities across the U.S. Comparable to Interstate Parking across B2B property management services, event parking, monthly contracts, and geographically diversified operations.
- Towne Park: Hospitality- and venue-focused parking management provider. Comparable to Interstate Parking's event/hotel/residential-adjacent parking mix (Fiserv Forum, US Bank Stadium, Residence Inn) and its B2B property management service offering.
- Republic Parking: Mid-sized parking management and consulting firm operating across multiple U.S. cities. Comparable as a similarly sized regional operator with managed services, event parking, and municipal contracts.
- Parking Management Inc. Operates and manages parking facilities in Midwest and other U.S. markets, with similar mix of self-park, attendant, event, and monthly products. Direct competitor to Interstate Parking in several overlapping cities.

Emerging players
- ParkMobile: Mobile payments platform for parking with a national footprint. Adjacent to Interstate Parking as a partner/channel (via integrations) but competes indirectly for consumer attention and venue-direct contracts.
