Their dynamic involves Andreessen generating a high volume of ideas for the firm's direction. Horowitz, being more decisive by nature, plays the crucial role of filtering and committing the firm to a specific path, preventing open-ended exploration from stalling progress.

Horowitz claims a VC firm's ability to win access to the most sought-after deals is more critical to success than its genius for picking winners. A strong brand that ensures access to competitive rounds can generate top-tier returns even with average picking ability.

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.

For a megafund like Andreessen Horowitz's $15B vehicle to generate venture returns, it must consistently capture a significant market share—roughly 10%—of all successful outcomes. This transforms their investment strategy into a game of market share acquisition across all stages, not just picking individual winners.

Unlike committees, where partners might "sell" each other on a deal, a single decision-maker model tests true conviction. If a General Partner proceeds with an investment despite negative feedback from the partnership, it demonstrates their unwavering belief, leading to more intellectually honest decisions.

Horowitz claims that winning competitive deals is a much larger component of VC success than simply picking the right companies. A firm with a brand and platform that can consistently win the best deals will automatically generate top-tier returns, even with average picking ability. This attracts the best pickers over time, creating a flywheel.

A16z's growth fund avoids traditional investment committees, which can lead to politicization and slow decisions. Instead, it uses a venture-style "single trigger" model where one partner can champion a deal, encouraging intellectual honesty and speed.

Anish Acharya reveals a core tenet of a16z's early-stage strategy: price is flexible, but ownership is not. For deals below a certain threshold (~$100M valuation), the exact price matters less than securing the ownership percentage required to deploy their extensive operational support model.

Ben Horowitz argues that waiting a decade for fund outcomes is too slow. Instead, a16z judges investors "at the point of attack"—how good they are at finding and winning deals with exceptional founders. This focuses on decision quality in the present, not lagging indicators.
