Southeast Asian ridesharing app Grab has just secured another round of financing and a new strategic partner. 

Booking Holdings a provider of online accommodations and travel e-commerce, and Grab Holdings Inc. the leading on-demand transportation and mobile services platform in Southeast Asia, recently announced that the two parties have entered into a strategic partnership.

With the partnership, Booking Holdings’ brands will have the ability to offer on-demand transport services through their apps, powered by Grab, and Grab customers will be able to book accommodations across the globe powered by Booking.com and agoda. In addition, Booking Holdings has invested US$200 million in Grab, recognizing Grab as the leading online-to-offline mobile (O2O) mobile platform in Southeast Asia. Grab has raised over US$2 billion for its current round of financing and is on track to raise over US$3 billion by the end of this year.

Todd Henrich, SVP and Head of Corporate Development for Booking Holdings, said, “Grab has scaled impressively across Southeast Asia over the last few years, establishing itself as a recognized leader in an increasingly competitive space, and we’re excited to partner with them to build even better travel experiences through technology.”

The partnership between Booking Holdings and Grab allows Grab users to book travel-related services through the app for the first time, and pay seamlessly using the region’s leading digital wallet, GrabPay. The partnership also highlights Grab’s commitment to becoming Southeast Asia’s leading everyday super app, offering ride-hailing, food delivery, parcel delivery and digital payments to millions in the region. Grab has a presence in 235 cities in 8 countries and enables 8 million micro-entrepreneurs through its platform.

Ming Maa, President of Grab said, “We are delighted to work with Booking Holdings to give our users even more everyday services to choose from when they open the Grab app. The online travel market in Southeast Asia is set to nearly triple by 2025 and we see numerous synergies between travel and transportation that will allow us to capitalize on this huge opportunity. As a global travel leader, Booking’s investment into Grab is a vote of confidence in our continued ability to execute and expand into different O2O verticals, and roll them out across the 235 cities in which we operate.”
