Southeast Asia’s superapp Grab has announced leadership appointments in Singapore and Vietnam, effective July 1, 2025. Alejandro Osorio, who currently leads Grab Vietnam, has been appointed Managing Director of Grab Singapore.
Ma Tuan Trong, Grab’s Country Commercial Head in Vietnam, will assume the role of Managing Director of Grab Vietnam, according to an announcement on Tuesday.
Moreover, Yee Wee Tang, who has led Grab’s Singapore business over the past few years, will transition to an expanded regional role as Group Managing Director of Operations. In this capacity, he will oversee multiple countries, ensure strategic alignment across operations, and manage platform safety as well as 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. 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. Under their leadership, we are confident that we will continue to deliver exceptional value to our users and partners,” said Wee Tang in a statement.
These appointments will take effect on 1 July 2025, supported by a comprehensive plan to ensure a smooth and seamless transition.
Alejandro began his journey at Grab as Director of Regional Strategy and Planning within the Regional Operations team based in Singapore. He later 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.
In his new role, Alejandro will guide Grab’s next phase of growth in Singapore. His focus 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 users and partners.
Meanwhile, Trong, who has spent 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 business from its inception to its current market-leading position, while also driving rapid growth in Grab’s grocery, parcel delivery, omnicommerce, advertising, and corporate solutions.
Under his strategic leadership, Trong has been a key force in increasing user and merchant engagement through effective cross-selling across Grab’s services.
His expertise in launching new 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.
