Investor Viktor Orlovsky reveals his mental model for evaluating founders: he compares new prospects to his "role models" of obsession and leadership. This method of pattern-matching against successful archetypes from his portfolio helps him decide who to back.

Elite talent manifests in two primary ways. An individual is either in the top 0.01% on a single dimension (e.g., tenacity, sales), or they possess a rare Venn diagram of skills that don't typically coexist (e.g., a first-rate technologist who is also a first-rate business strategist).

Over-diligencing for well-rounded perfection is a mistake. The best companies rarely excel in every area initially. Instead, investors should identify the one "spike"—the single dimension where the company is 5-10x better than anyone else—as this is the true indicator of outlier potential, rather than looking for a company that is A+ across the board.

a16z's investment philosophy is to assess founders on how world-class they are at their core strengths. Horowitz warns it's a mistake to pass on a uniquely talented founder due to fixable weaknesses (e.g., no go-to-market plan) and an equal mistake to back a less talented founder just because they lack obvious flaws.

Ben Horowitz states a common VC mistake is over-indexing on a startup's weaknesses. The better investment is a team that is unequivocally the best at a single, critical thing. Being "pretty good" at everything is a red flag, as greatness in one area is what drives extraordinary outcomes.

Good references are insufficient; you need exceptional ones. Sean Maguire applies the chess ELO rating system to due diligence, arguing that only a top-tier individual can accurately identify another potential outlier. Merely "good" people often cannot spot true genius, making the source of the reference critical.

Rabois's investment formula requires a founder to be the absolute best he's ever met in at least one specific dimension—be it intelligence, tenacity, or strategy. He avoids investing in founders who are merely B+ across the board, betting instead on extreme, world-class exceptionalism.

Horowitz instructs his team to focus on how exceptionally good a founder is at their core competency. He warns against two common errors: passing on a world-class individual due to fixable weaknesses, and investing in a founder with no glaring flaws but no world-class strengths.

Most VCs can identify an 'A' founder versus a 'C' founder. The real game, where outlier returns are generated, is in the much harder task of discerning the generational 'A+' founder from the very capable 'A-' founder. Founders Fund was built on this.
