Taxi app Hailo's merger with Daimler subsidiary mytaxi launches in Ireland today.
The consolidation will see both firms operate under the mytaxi brand across 50 European cities.
Hailo users will be prompted by their existing app to migrate over to the new mobile offering in the next few days.
In Ireland, some 10,000 drivers have been making the changeover to the new app for the last several weeks.
Passengers will still have access to their old Hailo app for a number of months to give them additional time to become familiar with the new product if necessary.
"Both tech teams in Hailo and mytaxi have worked over the last six to nine months to take the best features of each and combine them into one mytaxi platform," the head of Hailo's Irish operations and now mytaxi's general manager in Ireland, Tim Arnold, said.
"The first thing you'll recognise is that the mytaxi app looks really familiar, the colour scheme is still the same - and the 'Irishness' that leant to the success of Hailo here is still visible."
Andrew Pinnington, the chief executive of mytaxi, said that the development was very natural as "the geographies of the two firms were complementary and their business approaches were so similar".
"We've now got a business that is in 10 European markets with around 120,000 registered drivers; that offers real scale and scope that wasn't possible while operating on a smaller basis," he said.
"Our majority owner Daimler has a fairly strong balance sheet with quite a lot of cash sitting around and it has a real strategic interest in driving this business," Mr Pinnington added.
