Taxi booking service Click A Taxi is expanding into Germany, Austria, Switzerland and Spain, after securing $1.5m in investment.

Investment comes from ZYB co-founder, Podio CEO and “serial entrepreneur” Tommy Ahlers, who said Click A Taxi is “a great example of applying clever digital solutions to an old industry”.

The expansion means the service is now available in nine countries across Europe (including the UK, Ireland, Sweden, Norway and Denmark), with Click A Taxi claiming to be “the largest taxi app in the world”.

Click A Taxi essentially serves as a hub for existing taxi companies. Users download the app then, when they want to make a booking, select their location, choose a time and pick from the various taxi options Click A Taxi presents. The app now works in around 2,500 cities across Europe.
