An investor might correctly identify a company's flaw but still be wrong to pass, as great founders often fix those issues. This requires investors to have the humility to admit their ultimate conclusion was wrong, even if their initial analysis was correct, and be willing to re-engage with the startup.

SV Angel's model is to remain hands-off until founders face a critical "inflection point." When COVID hit, Airbnb's board told Brian Chesky they couldn't raise money. Conway stepped in, provided conviction that the game was not over, and helped them secure a round in ten days, saving the company.

Unlike seed-only funds, multi-stage investment firms have a structural advantage: they can rectify a mistaken pass on an early round by investing later. This provides a crucial second chance to partner with founders they initially misjudged, as Andreessen Horowitz did after passing on Solana's first round.

A core part of a16z's growth fund strategy is to invest in companies the firm's early-stage team passed on. This acts as an internal "fix the mistake fund," providing a structured way to correct errors of omission and get a second chance at breakout companies.

For VCs, the financial impact of passing on a generational company far exceeds the losses from investments that go to zero. Author Eric Reiss emphasizes that investors must be psychologically resilient to these misses, as opportunity cost is the most expensive mistake.

In venture capital, the potential return from a single massive winner (1000x) is so asymmetric that it dwarfs the cost of multiple failures (1x loss). This reality dictates that the primary focus should be on identifying and capturing huge winners, making the failure to invest in one a far greater error than investing in a company that goes to zero.

Bessemer Venture Partners publicly lists massive companies it passed on to foster a learning culture. This highlights their philosophy that the opportunity cost of missing a transformative company (a crime of omission) is far more damaging than investing in one that fails (a crime of commission).

The financial loss from a failed startup investment is capped at 1x the capital. Conversely, the opportunity cost of passing on a company that becomes worth billions is uncapped and unlimited. This asymmetry dictates that VCs should fear sins of omission more than sins of commission.

Passing on a company you admire due to mismatched timing, valuation, or uncertainty is a difficult but crucial discipline. True investment judgment involves tracking a thesis over time and waiting for the right entry point, rather than just identifying a single good team or idea.
