An app that allows drivers to find and reserve convenient free parking spaces has raised £1.7 million on the crowdfunding platform Crowdcube.

JustPark connects drivers to the owners of parking spaces to and has a deal with BMW which integrates the app into cars’ dashboard displays.

After listing on Crowdcube, the business reached its target £1 million in just four days and at time of writing had raised more than £1.7 million.

The company will keep the funding round open for a short time, it said.

New investors join alongside existing backers BMW iVentures, which ploughed £250,000 into the business in 2011 and global venture capital outfit Index Ventures.

JustPark founder Anthony Eskinazi said: “We are hugely excited to offer our existing users and members of the public the chance to claim a stake in JustPark’s future growth, particularly given that our business is all about collaboration.

“We are operating at the heart of the sharing economy, with our customers providing each other with the solution to the parking headache by opening up their underused parking spaces to drivers.

“This crowdfunding round will allow us to work together with our most passionate users to build the business to greater heights.”

JustPark is the 200th business to be funded on Crowdcube and is its biggest technology investment to date. Some 2350 investors ploughed an average £700 into the deal, it said.

The biggest deal on Crowdcube overall was Kevin McCloud’s Hab Housing, which raised nearly £2 million in two years ago.

Crowdcube co-founder Luke Lang said: “It’s great to see our community of 140,000 registered investors getting an opportunity to invest alongside leading venture capital firms like Index Ventures and BMW iVentures.”
