Ola from India, Didi Kuaidi from China, Lyft from the US and GrabTaxi from Singapore (which have raised $7 billion collectively) have joined hands in a strategic alliance and will start rolling out products in the first quarter of 2016. Ola and GrabTaxi have joined the alliance initially started by Lyft and Didi Kuaidi in September and claims to cover 50% of the world’s population across Southeast Asia, India, China and the US.

This alliance is a follow up of reports from January this year when Ola was planning to tie with GrabTaxi to form a global taxi alliance to take on Uber. The alliance was driven by SoftBank Capital and San-Francisco-based Flywheel.

Sharing tech and knowledge: These 4 companies will collaborate to use each other’s technology, local market knowledge and business resources to offer international travelers rides using the same application native to their country. The companies will handle mapping, routing and payments for their respective countries.

Ola’s funding: Last month, Ola raised $500 million from SoftBank Group, DST Global and China’s Didi Kuaidi among other investors for growth related activities and mobility solutions. SoftBank had invested (pdf) $250 million in GrabTaxi in December 2014 and had also led a $210 million investment in Ola in October 2014.
