Who we are

AppyWay is the industry-leading SaaS solution decarbonising cities by empowering local authorities to digitally manage their kerbside and share kerbside data with fleets and drivers.

Our journey began with AppyParking, an app born from the frustration of finding and understanding parking on the streets of London. During the app's creation, it was clear that cities lacked shareable, machine-readable, standardised parking restriction data. So we built the UK's largest set of standardised kerbside data, in turn discovering the untapped potential beneath everyone's feet.

Today, we're Europe's leading intelligent kerbside platform, helping cities and drivers optimise operations and transition to net zero by uniting parking/loading maps, occupancy data, and cashless payments.

Our impressive client roster includes local authorities such as Edinburgh, Southwark, Lambeth, Haringey, Harrogate, Cambridgeshire, Cornwall, Dorset, Dublin and, more recently across the pond, New York City. Additionally, our apps and API are trusted by tens of thousands of drivers and fleets including Blue Badge innovators Motability Operations.

We are proud to have the support of top investors, including Hyundai Motor Company, Aviva Ventures, Mastercard and Esri. To date, we have raised over £20 million in funding, allowing us to continue building something big from the ground up.

If you're passionate about tangible solutions to help decarbonise the world, then AppyWay is the perfect place for you. Come and make your mark on a company you can call your own!
