Even with big wins, a venture portfolio can fail if not constructed properly. The relative size of your investments is often more critical than picking individual winners, as correctly sized successful investments must be large enough to overcome the inevitable losers in the portfolio.

For a venture capital fund, the costliest error isn't investing in a startup that fails (a sin of commission); it's passing on one that becomes a massive success (a sin of omission). This fear drives a high-volume sourcing strategy that prioritizes seeing every potential deal.

Contrary to the popular debate, venture is primarily an access game, not a picking game. The core challenge is building a system to see a high volume of exceptional founders and then win the allocation. Once that is achieved, selecting which ones to back becomes straightforward.

A smaller fund size enables investments in seemingly niche but potentially lucrative sectors, such as software for dental labs. A larger fund would have to pass on such a deal, not because the founder is weak, but because the potential exit isn't large enough to satisfy their fund return model.

Investor Eric Byunn argues against the VC obsession with backing companies pursuing "winner-take-all" monopolistic outcomes. He asserts that, demonstrably, most successful companies are built in markets with multiple winners. Being a strong number two or three can still lead to a fantastic outcome for founders and investors.

A successful seed fund model is to first build a diversified 'farm team' of 20-25 companies with meaningful initial ownership. Then, after identifying the breakout performers, concentrate heavily by deploying up to 75% of the fund's capital into just 3-5 of them.

The success of a category is often driven by one exceptional company. Instead of diversifying across a hot sector like 'space tech,' investors generate better returns by concentrating capital in the clear winner, like SpaceX, which captures a disproportionate share of the market value.

Conventional venture capital wisdom of 'winner-take-all' may not apply to AI applications. The market is expanding so rapidly that it can sustain multiple, fast-growing, highly valuable companies, each capturing a significant niche. For VCs, this means huge returns don't necessarily require backing a monopoly.

An investor attributes missing Uber, Pinterest, and DoorDash to his fund's structure. With only 10-15 investments per fund and a "responsible investing" mandate, each decision is heavily weighted, leading to a slower, more cautious approach that is ill-suited for capturing power-law returns.
