If you thought the battle between Southeast Asia’s ride-hailing leader Grab and its Indonesia-headquartered foe Gojek couldn’t get any more intense, it has.

Gojek pushed its business across Southeast Asia last year, and Singapore-based Grab has spent the last two years trying to unseat its rival in its native Indonesia. The fundraising battle has gone stratospheric with both sides raising billions; Grab’s last round was $6.5 billion and its investors span SoftBank, Toyota and Microsoft, while Gojek is in the process of completing a round of at least $2 billion from a cast of backers that include Google, Tencent and Mitsubishi.
