Core Philosophy

Andreessen believes that the key characteristic of venture capital is that returns follow a power-law distribution. A tiny fraction of deals drives virtually all returns. He thinks that the entire art of venture capital is the big breakthrough for ideas, and that most big breakthrough technologies and companies seem crazy at first. He believes that you cannot predict breakthroughs, but you can tilt into radical ideas and assemble a portfolio of mis-priced optionality.

Decision-Making Patterns

• **Returns Follow a Power Law:** About 15 of the 200 fundable startups a year will generate 95% of all economic returns. Understanding this is essential to venture capital.

• **Invest in Successful, Non-Consensus Ideas:** You make all your money on successful and non-consensus ideas. If something is already consensus, money will have already flooded in and the profit opportunity is gone.

• **Cultivate a Prepared Mind:** Enter meetings with a zen-like blank slate of perfect humility, saying "teach me." Learn as much as you can about as many things as you can.

• **You Cannot Predict Breakthroughs:** By their nature, you can't predict what they will be. The best strategy is to assemble a portfolio of mis-priced optionality rather than trying to predict the future.

• **People Are ~90% of the Decision:** About 90% of the investment decision is about the people. He is looking for a magic combination of courage and genius.

Mental Models

• **Power-Law Returns:** A small number of investments or decisions produce the vast majority of returns. You have to find the outliers.

• **Non-Consensus and Right:** The money is in ideas that are both successful and non-consensus. Consensus ideas are already fully priced.

• **The Prepared Mind:** Learn broadly and enter every meeting with humility and a willingness to be taught.

• **Mis-Priced Optionality:** In complex adaptive systems, the best strategy is to buy optionality at the right price rather than predict the future.

• **Courage and Genius:** The magic combination in founders is courage (not giving up in the face of adversity) and genius.

He writes clearly and believes that the person who writes down the thing has tremendous power. He is decisive, often making investment decisions quickly, and values clear, written thinking.

Contradictions & Edges
