What It Covers

Tim Sullivan shares four decades of wisdom from leading Yale's private equity investing from 1986 to 2025, covering venture capital selection, buyout firm evolution, market cycles, and why repeating past institutional success grows increasingly difficult.

Key Questions Answered

• •Venture Capital Access: Top venture firms attract best entrepreneurs through positive feedback loops, creating systematic advantages. Yale identified 15 target firms in the late 1980s by asking existing managers who they respected, establishing relationships when insurance companies were exiting after early 1980s bust, gaining entry at optimal timing.
• •Operational Value Creation: Financial engineering became commoditized as Wall Street taught leverage techniques widely. Yale focused early on buyout firms combining financial expertise with genuine operating capacity, not just ex-Fortune 500 CEOs but operators with appropriate skill sets for smaller company boards, avoiding undermining existing management while providing strategic guidance.
• •Deal Sourcing Evolution: Competitive intensity requires firms to engage potential acquisitions months or years before formal auctions, not just six-week investment bank processes. Verticalized teams with dedicated industry knowledge enable longer evaluation periods to understand assets deeply, control overpayment risk, though this creates firm cohesion challenges as specialists replace generalists across investment committees.
• •Manager Selection Discipline: Institutions must realistically assess competitive advantages in accessing top-tier managers. Venture remains lottery ticket business where winners concentrate at specific firms. Without existing relationships or clear access strategy, institutions face mediocre returns after fees and illiquidity costs. Sample size problems plague emerging manager selection when five successful deals may represent luck not skill.
• •Exit Discipline Framework: Buyout managers anchor to cost, holding underperforming assets hoping for improvement rather than accepting mediocre outcomes early. Firms should sell struggling investments after three to four years at 0.8x to 1.4x returns, freeing capital and management time for new opportunities, instead of grinding through eight to twelve year holds on assets unlikely to improve meaningfully.
