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.

For early-stage AI companies, performance should be measured by the speed of iteration, shipping, and learning, not just traditional metrics like revenue. In a rapidly evolving landscape, the ability to quickly get signals from the market and adapt is the primary indicator of future success.
With AI commoditizing technology, the sustainable advantage for startups is the speed and discipline of their experimentation. Founders who leverage AI to operate 10x faster will outcompete those with static tech advantages, as execution velocity is far harder to replicate than a feature.
Unlike traditional software development, AI-native founders avoid long-term, deterministic roadmaps. They recognize that AI capabilities change so rapidly that the most effective strategy is to maximize what's possible *now* with fast iteration cycles, rather than planning for a speculative future.
Redpoint Ventures' Erica Brescia describes a shift in their investment thesis for the AI era. They are now more likely to back young, "high-velocity" founders who "run through walls to win" over those with traditional domain expertise. Sheer speed, storytelling, and determination are becoming more critical selection criteria.
With AI commoditizing the tech stack, traditional technical moats are disappearing. The only sustainable differentiator at the application layer is having a unique insight into a problem and assembling a team that can out-iterate everyone else. Your long-term defensibility becomes customer love built through relentless execution.
Since startups lack infinite time and money, an investor's key diligence question is whether the team can learn and iterate fast enough to find a valuable solution before resources run out. This 'learning velocity' is more important than initial traction or a perfect starting plan.
In a fast-moving category like AI coding, platform features are fleeting. The more durable factor is the founding team's vision and ability to execute. Users should follow the founders of these companies, as choosing a tool is ultimately a long-term bet on a person's leadership and trajectory.
There's a growing belief in venture that experienced, second-time founders may be at a disadvantage in the AI era. Younger founders who grew up natively with new tools can move faster because they don't have to unlearn established, but now obsolete, ways of working.
AI tools enable solo builders to bypass the slow, traditional "hire-design-refine" loop. This massive speed increase in iteration allows them to compete effectively against larger, well-funded incumbents who are bogged down by process and legacy concerns.
In the AI era, technology moats are shrinking as tools become commoditized. Consequently, early-stage investors increasingly prioritize the founding team itself, specifically their execution velocity and ability to leverage AI, over any specific technical advantage.
