ABC Taxis' fleet of 340 vehicles has been sold to a Welsh digital hire firm as part of its planned growth into the East Anglian market.
The Norwich taxi company, which has been operating in the city since 1994, was bought by Veezu for an undisclosed sum.
It said that the sale would enable drivers to access new technology to improve efficiency and increase their earning potential.
ABC taxi drivers are not employed directly by the company, instead are self-employed but operate under the brand name.
The deal is part of Veezu's planned expansion into East Anglia, which saw it also purchase Panther Taxis in Cambridge.
Nathan Bowles, CEO of Veezu, said that the takeover will help improve services offered to passengers.
"We are focused on continually improving our service to give passengers what they want, and right now partnering with more drivers with the latest technology will help us give their passengers the best service possible," he said.
“These acquisitions extend our reach to the east of the country and provide the opportunity for Veezu to build on hyperlocal activities to ensure the ABC and Panther brands remain at the centre of their communities across Cambridge and Norwich."
