In this episode, Jamie Lee, Co-Founder and Managing Partner of Tamarack Global, reveals how his fund achieved an exceptional 19.2% unicorn hit rate - the highest of any seed-stage fund. (00:37) Jamie discusses how founder referrals, particularly from unicorn founders, serve as the strongest signal for identifying breakout companies. He explains Tamarack's hedge-fund-level diligence approach applied to seed-stage investments, the importance of intuition in venture investing, and his bullish outlook on the $42 trillion global labor market opportunity in humanoid robotics.
Co-Founder and Managing Partner of Tamarack Global, Jamie Lee has built one of the most successful track records in seed-stage venture capital with a 19.2% unicorn hit rate. He previously spent eight years at Goldman Sachs followed by a role at Coatue Management under Philippe Laffont, where he learned to apply hedge fund-level diligence to venture investing. At Tamarack, he has deployed $100 million across two funds with total co-investment reaching $300 million, focusing primarily on deep tech and industrial automation opportunities.
Host of How I Invest podcast, David Weisburd conducts in-depth interviews with leading venture capitalists and investors about their strategies and insights. He brings extensive experience analyzing investment approaches and has built a platform for sharing actionable investing wisdom from top performers in the industry.
The most powerful signal for identifying unicorn companies comes from referrals by proven unicorn founders. (00:37) Jamie explains that when a "five out of five founder" calls with a recommendation, he meets that person within 24 hours. These founders often have commercial relationships with or have employed the people they're recommending, giving them asymmetric information about talent quality. For example, Tom Mueller from SpaceX knows every defense and aerospace entrepreneur because they've worked for him, making his referrals incredibly valuable for identifying the next generation of breakout companies.
Most seed-stage investors use the "unknowable" nature of early markets as an excuse for shallow diligence. (05:05) Jamie brings hedge fund-level research intensity to seed investments, creating 50-page memos on companies and sharing detailed analysis with growth investors for subsequent rounds. This approach helps win competitive deals because founders recognize the value of having an investor who deeply understands their business and can help with future fundraising. The key is becoming an "investigative journalist" who uncovers information asymmetries that others miss.
Rather than waiting for scheduled fundraising rounds, Tamarack proactively identifies companies showing "escape velocity" and preempts their next funding round. (17:01) When portfolio companies are hitting major milestones or winning significant contracts, Jamie calls them immediately to offer additional capital before their planned Series A. This concentrated approach allows them to increase ownership in their best-performing companies at favorable valuations, rather than being diluted by waiting for competitive later rounds.
Philippe Laffont at Coatue taught Jamie to rank every investment opportunity from 1-5 based purely on gut instinct. (23:02) The correlation between gut scores and actual performance is "striking" - companies ranked as true 5s significantly outperform those where investors talked themselves into a 5 rating. (24:21) When you see a real 5, "you feel it at the deepest part of your gut and you just know it's a five." This intuitive scoring system helps identify conviction opportunities versus marginal bets.
The global physical labor market represents a $42 trillion annual opportunity, with many jobs having 150% annual turnover rates. (12:05) When factoring in disability, insurance, and low productivity, warehouse workers cost companies $150,000-200,000 annually. (14:41) Humanoid robots priced at $80,000-100,000 that work 15 hours daily, seven days a week, with no sick days or unions, represent a massive arbitrage opportunity. One 3PL player has already expressed interest in 85,000 humanoids from Figure, representing $8.5 billion in potential annual recurring revenue from a single customer.
