PST Advisors

PST Advisors

Preston Tsao founded PST Advisors in 2015 to manage the wealth generated from his career as a technology investor and operator. The capital primarily originates from the 2006 sale of Metromedia China, a telecom and media holding company, to Liberty Media. Tsao was previously a General Partner at Crystal Ventures, where he made early-stage commitments to foundational enterprise technology companies including WebEx and Netscreen Technologies, each acquired for significant returns. PST Advisors invests across the capital structure, with a focus on early-stage venture capital, growth equity, and select private credit opportunities in North America and Asia. The firm concentrates on enterprise software, AI and machine learning, digital health, and fintech — sectors where Tsao's personal operating experience provides structural diligence advantages. The office favors direct investments and co-investments alongside trusted venture capital relationships rather than blind-pool fund commitments. Known deal participation remains largely private by design. Team size and assets under management are not publicly disclosed. The firm operates from New York without announced satellite offices. There are no known adjacent philanthropic foundations or operating companies formally associated with PST Advisors. The office maintains a deliberately low profile, with no public-facing website or active media presence, consistent with a single-family office that prioritizes capital preservation and discreet deployment over brand-building. PST Advisors' structural differentiator is its pure operator-to-investor lineage: a single principal who transitioned from founding a venture firm and building an operating business to managing scaled family capital. This architecture creates concentrated decision-making with no external LP constraints, allowing for patient capital deployment in technical sectors where the founder holds domain expertise uncommon among generalist family offices.
