Episode notes
Why ETA Is Micro Private Equity But Different
- ETA is effectively lower-market private equity but distinct because the playbook (jockey + operational work) matters more than pure deal size.
- Jon warns big funds avoid this space because it's manual, unscalable, and requires hands-on operators.
Stanford Study Validates Strong ETA Returns
- The Stanford dataset shows ~35% net annual returns over decades, robust even after removing outliers and failures.
- Jon uses this study to argue ETA offers attractive, low-volatility, risk-adjusted returns versus public markets' forecasted low returns.
Use The Search Phase To Vet CEO Potential
- Treat the search phase as CEO training: evaluate coachability, tenacity, and decision-making before funding an acquisition.
- Jon emphasizes the year-or-more interview process where funds watch searchers in-class and during outreach.
