Ethan Choi has built a reputation for leading Accel's flagship investments in category-defining, product-led growth companies like 1Password, Klaviyo, Nuvemshop, Pismo, Invoca, and Shogun, often coming in as a core board member and long-term partner to these teams rather than as a purely financial investor.

• Deep conviction in the massive scale of AI infrastructure and compute build-outs. He frequently discusses the direct correlation between power consumption and revenue potential, specifically noting calculations where one gigawatt of compute could theoretically generate ten billion dollars in annual recurring revenue and serve hundreds of millions of users.
• Predicting a major displacement of legacy software by AI-native companies. He argues that even established Systems of Record are vulnerable to being replaced by new players that build depth and breadth at lightning speed, rather than just acting as a wrapper around existing tools.
• Intense scrutiny of market data and survey methodology. He values statistical significance and transparency, evidenced by his detailed critique of a competitor's report on enterprise AI adoption where he questioned the sample size and firmographics used to claim one model was beating another.
• Enthusiasm for the next evolution of technology beyond text-based models, specifically AI agents and physical AI. He highlights advancements in world models, such as Genie 3, and views the integration of AI into physical robotics and autonomous agents as a critical area of progress for the coming year.
• A focus on the financial macro-economics of the AI race. He pushes back against fear, uncertainty, and doubt regarding capital expenditures, arguing that the massive investment in compute is driven by the smartest teams in the world and that demand for intelligence is effectively infinite.
