Cassandra Leong

Senior Director Brand Marketing

Marriott International

Cassandra is a senior marketing leader with experience building and scaling high-growth consumer technology and global travel brands across Asia Pacific. She currently leads brand marketing for Marriott International’s Marriott Bonvoy programme and its Premium and Select brand portfolio across APEC (Asia Pacific excluding China).

Previously, she helped define Carousell’s brand alongside its founders and led multi-market marketing across the region. At Airbnb, she grew the Singapore business and launched the brand across diverse markets including China, India, and Japan.

Cassandra is deeply curious and mission-driven, drawn to work that creates genuine value in people’s lives. She thrives in fast-paced, ambiguous environments and brings clarity, structure, and scale to ideas. As a judge, she’s particularly interested in work that pairs strong strategy with cultural insight and distinctive storytelling — and above all, work that has fun and makes you feel something.
