Three London cabbies are about to hit the United States with their taxi-hailing business.
Hailo, which was set up last year, allows customers to use iPhones or Android smartphones to call licensed taxis without waiting in the street hoping one will pass by.
Taxi drivers Russell Hall, Gary Jackson and Terry Runham set it up with internet entrepreneurs Ron Zeghibe, Caspar Woolley and Jay Bregman.
They had backing from Atomico Ventures, the backers of Skype co-founder Niklas Zennstrom.
Hailo has just won another chunk of funding, $17 million (£11 million) from venture capital firm Accel Partners to take on the US.
Accel has invested in Facebook, Groupon and Angry Birds creator Rovio.
Hailo, which is now the largest app-based taxi network in any city in the world, wants to expand further across London as well as Dublin and into the US.
