## Questions

### Who is behind PST Advisors?

PST Advisors was founded by Preston Tsao, a technology investor and former General Partner at Crystal Ventures. His track record includes early investments in WebEx and Netscreen Technologies, as well as the founding and sale of Metromedia China to Liberty Media in 2006. The firm name derives from his initials.

### What is the firm's known posture on co-investments?

PST Advisors prefers direct investments and co-investments alongside established venture capital firms rather than making blind-pool fund commitments. This aligns with Tsao's history as a venture GP who sourced his own deal flow and maintained strong relationships within the early-stage enterprise technology ecosystem.
