Hunter Walk argues that ownership in a startup is more important than valuation for seed venture capitalists, especially in the context of his work at Homebrew, where they managed funds under $100 million. He explains that while they occasionally turned down investment opportunities due to pricing, it was primarily because the round size was too large for them to take a lead position, not because of minor differences in ownership percentages. For example, a small change in investment amount, like $1.5 million versus $1.8 million for 15% ownership, rarely influenced their decisions. Walk reflects on the dynamic nature of venture investing, likening it to a boxer’s strategy that changes when faced with real-life challenges. He emphasizes the need for a flexible approach rather than rigidly sticking to initial financial models. Making investment decisions without a proper framework can lead to a portfolio that underperforms. He also mentions his experience with new venture firms through Screendoor, highlighting the variety of strategies different firms employ for portfolio construction.
