334. A Decade at Costanoa, Where Large Multistage Funds Fail Founders, Denominator v. Numerator Effects, and Tips on Startup Selection (Greg Sands)

Venture capital firms operating at the seed and Series A stages must balance concentrated, high-conviction investing with specialized operational support to drive founder success. Costanoa Ventures, led by founder Greg Sands, employs a "builder ops" model that integrates expert resources in sales, marketing, and talent to complement capital deployment. This approach prioritizes a rigorous, independent evaluation of people, product, market, and price to mitigate bias and foster objective decision-making. By maintaining a concentrated portfolio of approximately 35 companies per fund and utilizing a dedicated opportunity vehicle for follow-on investments, the firm optimizes its ability to support high-growth enterprise technology and fintech startups. This strategy reflects a shift from traditional, fragmented seed-stage investing toward a more hands-on, partnership-driven model that emphasizes long-term founder mentorship and the early validation of product-market fit.
