Rockstar🎓
Top SchoolSiong Ong is a seasoned entrepreneur and engineer with 16 years of experience building and scaling product-led startups from San Francisco to Malaysia. As a co-founder at Prefer and early engineer at Envoy, he helped define product and engineering direction that led to Series A backing and rapid company growth. He founded graffitiGeo out of college, a Y Combinator-backed location app later acquired by Loopt, and has repeatedly shipped consumer and mobile products at scale. An active investor and advisor (VGS, Kenzie, Handshake, Agave), he blends hands-on backend expertise—demonstrated by caching and dependency work on the Rabl templating library—with a talent for early-stage product discovery. Now leading a new venture back in Malaysia, he hires across disciplines while running stealth projects that leverage his history of turning prototypes into funded exits.
