Key Questions Answered

• •Fund Size Strategy: Venture capital follows a death-of-the-middle pattern where firms must be either large generalists or small specialists to win consensus deals. Mid-sized generalist funds struggle because they lack both the comprehensive resources of large funds and the deep expertise of specialized boutiques, making it harder to convince top entrepreneurs.
• •Founder Evaluation Framework: Invest in founders who can materialize three things: labor (people follow them for 50% pay cuts), capital (strong fundraising ability), and customers (can close first five enterprise deals). Additionally, seek founders who study industry history extensively and possess Count of Monte Cristo-level motivation for revenge or redemption beyond just making money.
• •Hostages vs Customers: The best companies have hostages, not customers—meaning switching costs are prohibitively high. Systems of record like Workday create lock-in through data integration. Startups should target greenfield markets where new company creation rates are high enough that customers freely choose the best product rather than attempting to convert entrenched incumbents.
• •Series Valuation Risk: Raising at excessively high valuations creates existential risk because the first question in every subsequent fundraise or acquisition conversation is last round price. If a company raises Series A at $200 million with minimal revenue, even reaching $20 million ARR makes the Series B psychologically impossible for investors to justify.
• •AI Labor Displacement: Software companies fall into three categories regarding AI impact: impervious incumbents like Workday that add AI features, decimated players like Zendesk where AI eliminates seat licenses entirely, and middle-ground companies like Adobe facing partial displacement. The key is backing into sticky systems of record after initial AI-driven growth to prevent commoditization.
