It operates a fleet of motorcycle taxis, private cars and other services -- from massage and house cleaning to grocery shopping and food delivery -- available via smartphone, although the Singapore launch will only offer car taxis.
The Singapore market has been dominated by homegrown tech firm Grab since it bought US-based rival Uber's ride hailing and food business in Southeast Asia earlier this year, ending a bruising competition.

Go-Jek's beta app was due to be available for download from Thursday to a limited number of customers, and will only cover a designated part of the city-state.
