## Questions

### How does WS Investments source its deal flow?

Deal flow originates primarily through the parent law firm's corporate practice, which advises thousands of emerging companies on formation, venture financings, M&A, and public offerings. This embedded position within the legal infrastructure of Silicon Valley startup creation gives the investment team visibility into companies earlier than most institutional venture investors. The firm sees deal flow at the point of incorporation and initial counsel, often before a formal venture round is contemplated.

### Does WS Investments commit to external venture funds or only make direct investments?

The primary known activity is direct early-stage investing in portfolio companies. The firm's proprietary capital model—investing the partnership's own capital rather than managing third-party funds—gives it flexibility on hold periods and follow-on decisions. There is no public record of the firm participating as a limited partner in external venture capital funds.
