Private Equity investors often misunderstand the VC model, questioning the lack of deep due diligence. They fail to grasp that VCs operate on power laws, needing just one investment to return the entire fund, making the potential for exponential growth the only metric that truly matters.

The memo details how investors rationalize enormous funding rounds for pre-product startups. By focusing on a colossal potential outcome (e.g., a $1 trillion valuation) and assuming even a minuscule probability (e.g., 0.1%), the calculated expected value can justify the investment, compelling participation despite the overwhelming odds of failure.

While a $3-5 billion exit is an incredible achievement, the ambition in top-tier venture capital has scaled up. With tech giants valued in the trillions, VCs now underwrite investments with the potential for trillion-dollar outcomes, recalibrating what qualifies as a "sufficient" return.

Sequoia Capital's Roloff Botha calculates that with ~$250 billion invested into venture capital annually, the industry needs to generate nearly $1 trillion in returns for investors. This translates to a staggering $1.5 trillion in total company exit value every year, a figure that is difficult to imagine materializing consistently.

A Series A company's valuation isn't based on current financials. Instead, it reflects the purchase of an 'out-of-the-money call option'—a bet that the company could become immensely valuable. The goal is for this option to eventually expire 'in the money,' generating venture returns.

The standard VC heuristic—that each investment must potentially return the entire fund—is strained by hyper-valuations. For a company raising at ~$200M, a typical fund needs a 60x return, meaning a $12 billion exit is the minimum for the investment to be a success, not a grand slam.

Solo GP Zal Bilimoria intentionally keeps his fund size small and consistent at $50 million. This disciplined strategy is designed so that achieving a 5% stake in a billion-dollar company at exit would generate a $50 million return, covering the entire fund and ensuring strong performance from a single breakout investment.

The venture capital return model has shifted so dramatically that even some multi-billion-dollar exits are insufficient. This forces VCs to screen for 'immortal' founders capable of building $10B+ companies from inception, making traditionally solid businesses run by 'mortal founders' increasingly uninvestable by top funds.

VC outcomes aren't a bell curve; a tiny fraction of investments deliver exponential returns covering all losses. This 'power law' dynamic means VCs must hunt for massive outliers, not just 'good' companies. Thiel only invests in startups with the potential to return his whole fund.
