Meet the Founder
Sion Sung is an entrepreneur and operations executive with over a decade of experience across e-commerce, international trade, supply chain, and digital marketing. Sion Sung bootstrapped his first venture from inception to a successful exit, scaling operations across multiple marketplace channels before divesting in 2021. That self-built track record is the foundation ZUST GROUP is built on.
Sion Sung graduated from Georgetown University and served as an officer in the U.S. Army Reserve. His military service through the MAVNI program — a selective program recognizing individuals with critical linguistic and cross-cultural competencies — reflects the same international acuity that defines his commercial career. Sion Sung has lived and operated across South Korea, Singapore, and Peru, and conducts business fluently in English, Korean, and Spanish.
ZUST GROUP was established to consolidate what Sion Sung had already been executing independently: lean, accountable operations across diversified business lines, with an unwavering focus on durable outcomes over short-term positioning. Every entity under the group is held to that same standard.
