20VC: The AI Boom Will Create Enormous Roadkill: Who Wins & Loses | Why Founders Should Never Take Multi-Stage Money at Seed | Why Triple, Triple, Double, Double is Good Enough

What It Covers

David Frankel of Founder Collective joins Harry Stebbings to examine who wins and loses in the AI boom, why seed investing remains viable despite commoditization, why founders should reject multi-stage money at seed, and how secondary markets are reshaping fund management. Frankel draws on 18 years of investments including Uber, Suno, and Shield AI.

Key Questions Answered

• •Multi-stage money at seed: Founders who take large multi-stage fund checks at seed face a structural risk: the junior principal who championed them frequently departs for a new fund within 18–24 months. Without an internal advocate, the startup loses follow-on funding mandate precisely when it needs support most. Frankel estimates this abandonment scenario applies to roughly 95% of multi-stage seed-backed companies that fail to hit aggressive early milestones.
• •Seed fund sizing discipline: Founder Collective GPs are the single largest LP in their own funds, deliberately keeping fund size small to prioritize return multiples over management fees. The median outcome among the top 500 companies created over 25 years is $2.6B. Owning 5% of one such company returns the fund entirely, making disciplined small-fund seed investing mathematically viable without needing trillion-dollar outcomes.
• •Uncapped notes destroy seed economics: Frankel identifies uncapped convertible notes as structurally damaging for seed investors. When a company converts at a $100–300M valuation, the investor who took the risk 12–18 months earlier captures minimal upside relative to that risk. Founders benefit from the flexibility, but seed funds accepting uncapped notes are effectively subsidizing later investors who enter at defined, lower-risk price points.
• •"I love it because..." investment framework: Founder Collective opens every investment discussion by completing the sentence "I love it because..." If the team cannot finish that sentence compellingly, the investment does not proceed. The framework forces specificity around founder obsession, vertical edge, or unique insight rather than momentum or valuation, and has prevented both bad investments and, occasionally, good ones where valuation became an easy shortcut to rejection.
• •Secondary market liquidity as fund management tool: Secondary markets for top-100 private companies are currently at peak liquidity, with some positions trading at or above the last round price. Frankel recommends selling 20% of a position when it can return 25% of the fund, even while remaining long on the remaining 80%. Waiting for an IPO plus an 18-month lockup means potentially six-plus additional years of capital tied up for a possible 2x from current levels.
• •"Nepo baby" founder edge: Founders with deep childhood or family exposure to a specific vertical carry durable competitive advantages that generalist founders cannot replicate quickly. Frankel cites TJ Parker working in his father's pharmacy as a teenager before founding PillPack, and Evan at Rebar, who grew up watching his uncle's HVAC business before building AI quoting software for that industry. Vertical immersion from an early age produces insight that accelerates product-market fit.
