Superapp Grab appoints new heads in Singapore, Vietnam

Grab, Southeast Asia’s leading superapp, on Monday announced leadership appointments in Singapore and Vietnam, effective July 1, 2025.

Alejandro Osorio, who currently leads Grab Vietnam, has been appointed as managing director of Grab Singapore, while Ma Tuan Trong, presently country commercial head in Vietnam, will assume the role of managing director of Grab Vietnam.

Additionally, Yee Wee Tang, a pioneering leader at Grab who has led the Singapore business over the past few years, is transitioning to an expanded regional role as group managing director of operations.

In this capacity, he will oversee multiple countries ensuring strategic alignment across operations, as well as manage platform safety and driver and merchant operations regionally. Both Alejandro and Trong will report directly to Wee Tang.

"These appointments reflect Grab’s investment in talent development and its strong bench of leaders. Alejandro and Trong bring extensive experience and proven track records that will be instrumental in driving innovation and growth," said Wee Tang.

"Alejandro’s expertise in leading diverse markets will introduce fresh strategies in Singapore, while Trong’s capabilities in scaling businesses will deepen our reach within Vietnamese communities," he added.

Alejandro began his journey at Grab as director for regional strategy and planning, as part of the regional operations team based in Singapore. He subsequently advanced to country head roles in Thailand and Vietnam.

His leadership has been pivotal in strengthening Grab’s presence through strategic market expansion and innovative product and service offerings tailored to consumer and partner needs.

Alejandro will guide Grab’s next phase of growth in Singapore. This includes scaling the new GrabCab taxi business to improve transport accessibility and convenience, integrating Chope’s capabilities for a unified food experience, and leveraging GrabFin and GXS Bank to develop innovative financial products for Grab’s users and partners.

"Singapore’s openness to new ideas and commitment to public-private collaboration have given Grab invaluable opportunities to co-create industry-first solutions that truly make a difference in people’s lives," said Alejandro.

Ma Tuan Trong, with nearly seven years at Grab, has held several leadership positions within the Vietnam team, spanning marketing, deliveries, and commercials.

He has been instrumental in establishing and scaling Grab’s food delivery businesses from its inception to its current market leading position, as well as driving rapid growth in the adoption of Grab’s grocery and parcel delivery, omnicommerce, advertising and corporate solutions among users and partners.

Under his strategic leadership, Trong has been a key force behind increasing user and merchant engagement through effective cross-selling of Grab’s services, by leveraging the synergies of deliveries and mobility to offer more value to them.

This has further strengthened Grab’s position as the number 1 ride-hailing app in terms of brand that is most used and the leading food delivery service in Vietnam, according to reports by Kantar and Momentum Works respectively, Grab said in the release.

Trong's expertise in launching new business ventures and driving sustainable growth uniquely positions him to further expand Grab’s operations in Vietnam, foster greater economic empowerment for locals, and support the government’s key national priorities.

"Digitalization has profoundly improved the lives of our communities, and we are committed to working closely with the government through meaningful public-private partnerships that empower every Vietnamese to access better opportunities in the digital economy and support the nation’s socio-economic progress," said Trong.
