The Onion Theory of Startup Risk Ft. Marc Andreessen (a16z) & Andy Rachleff (Benchmark)

Executive Summary

In this video, venture capitalist Marc Andreessen outlines the "Onion Theory of Risk," a framework for understanding the fundamental relationship between startup execution, fundraising, and risk management. The core thesis is that a startup is essentially a dense bundle of various risks (the "onion") that must be systematically peeled away, layer by layer, through the achievement of specific milestones. This approach provides entrepreneurs with a structured roadmap for raising and deploying capital effectively while building a defensible business.
