Reading micro cues and interview skill as alpha

How do the best venture investors consistently spot unicorn founders before the rest of the market even knows they exist? In this episode, I talk with Jamie Lee, Co-Founder and Managing Partner of Tamarack Global, about sourcing asymmetric deal flow in deep tech and why founder referrals are the single strongest signal of future breakout companies. Jamie explains how Tamarack applies hedge-fund-level diligence at the seed stage, why intuition and pattern recognition matter as much as data, and how concentrated conviction—combined with relentless research—drives their unusually high unicorn hit rate. We also explore humanoid robotics, labor automation, and why the next industrial revolution is already underway.

Highlights:

• Why founder referrals outperform every other sourcing channel
• Venture beta vs. true asymmetric alpha
• Applying hedge fund diligence to pre-seed and seed investing
• Why most early-stage investors under-diligence founders
• The power of intuition and “gut scores” in decision-making
• Lessons Jamie learned from Philippe Laffont at Coatue
• Why long-term time horizons matter more than near-term metrics
• The humanoid robotics market and the $40T global labor opportunity
• Playing offense by preempting rounds in breakout companies
• Why conviction beats caution early in an investing career
