About William Lin
William Lin spent over a decade in venture capital, helping to build Forgepoint Capital from scratch and eventually becoming Managing Partner.
In The VC Field Guide, he distills the venture capital investment framework he developed across years of evaluating founders, markets, products, and deals. The book is written for investors, entrepreneurs, operators, and anyone who wants a practical, repeatable way to understand how venture capital works.
The framework focuses on how startup investors assess opportunity size, founder-market fit, product differentiation, decision-making, and deal structure. That makes the book useful both for people trying to break into venture capital and for founders preparing to raise capital.
Throughout his career, Lin focused on how the most prominent investors reason about uncertainty and asymmetric outcomes — the judgment that separates good venture decisions from lucky ones. The VC Field Guide: Fundamentals of Venture Capital was published by Wiley in 2023 to make that craft, traditionally learned through years of apprenticeship, teachable as a structured, repeatable process.
