A critical dichotomy exists between investors and founders. Investors who love an idea are prone to making compromises on team quality. Founders, however, must be deeply passionate about their idea, as starting a company is an irrational act that requires immense conviction to succeed.

AI agents can execute tasks, but they lack inherent values or taste. A founder's primary role evolves into clearly communicating and codifying their unique vision, design sense, and principles for the AI agents to follow, which is the real competitive advantage.

A founder's deep, intrinsic passion for their company's mission is critical for long-term success. Even with a sound business model, a lack of genuine care leads to burnout and failure when challenges arise. Leaders cannot sustain success in areas they consider a distraction from their "real" passion, like AGI research versus product monetization.

Don't start a company in a space you're indifferent to and ignorant of. Your founding idea must be anchored in either deep domain expertise ("what you know") or a genuine, intense passion for the problem ("what you care about"). Lacking both is playing on "extra hard mode."

True entrepreneurial success isn't about chasing hot topics like AI. It's about finding a niche, boring problem and developing a deep, multi-decade obsession with it. This requires a unique ability to find interest where others see none, which is a powerful competitive moat.

Many founders start companies simply because they want the title, not because they are obsessed with a mission. This is a critical mistake, as only a deep, personal passion for a problem can sustain a founder through the inevitable hardships of building a startup.

Unlike prior tech waves where founders aimed to build companies, many top AI founders are singularly focused on achieving AGI. This unified "North Star" creates a unique tension between long-term research and near-term product goals, leading to unconventional founder and company dynamics.

Instead of optimizing for a quick win, founders should be "greedy" and select a problem so compelling they can envision working on it for 10-20 years. This long-term alignment is critical for avoiding the burnout and cynicism that comes from building a business you're not passionate about. The problem itself must be the primary source of motivation.

YC has always prioritized founders over ideas. The new focus on AI coding proficiency deepens this philosophy. A founder's ability to rapidly iterate with modern tools is the key evaluation metric, as the original idea is increasingly seen as temporary and less important than execution velocity.
