The accelerating pace of AI development has democratized powerful tools, yet it simultaneously presents a unique challenge for founders: how to craft a compelling digital presence that transcends the generic. In a recent Y Combinator Design Review, Ryo Lu, Head of Design at Cursor, joined Aaron Epstein, General Partner at Y Combinator, to dissect the websites of early-stage startups built using AI coding tools. Their candid critique offered invaluable insights into the stark difference between merely functional design and truly effective communication, particularly for ventures navigating the burgeoning AI landscape.
At the heart of Ryo Lu’s feedback was a persistent question: "What is this? Is it for me?" Many of the reviewed sites, despite their innovative underlying technology, struggled with fundamental clarity. Founders often fall into the trap of assuming their audience shares their intimate understanding of the product. This leads to landing pages cluttered with technical jargon or abstract marketing copy that fails to immediately convey value. For high-end investment banks, investors, and consultants—a target audience for one startup—the messaging must be direct and unambiguous, not veiled in vague, high-level terms.
A recurring theme was the emergence of what Ryo Lu dubbed "AI slop." As generative AI tools become more sophisticated, they also tend to produce a recognizable aesthetic: ubiquitous purple gradients, overly dramatic shadows, and predictable typography. This homogeneity, while efficient, dilutes brand identity. Startups need to deliberately break free from these defaults, cultivating a distinct visual style that communicates intentionality and professionalism, rather than appearing as a template-driven afterthought.
Consistency in visual style across an entire website is paramount.
Disjointed design elements, inconsistent color palettes, or shifting typographic choices between pages can erode user trust and signal a lack of polish. Beyond aesthetics, the strategic placement and prioritization of Calls to Action (CTAs) proved critical. Overloading a page with multiple buttons or unnecessary animations creates a disorienting experience. Ryo Lu stressed that "each page should only have one main CTA," guiding the user clearly through the desired interaction without distraction.

The analysis also highlighted the importance of speaking the user's language. Several sites presented complex technical concepts or internal project names without adequate explanation, leaving visitors confused. Instead of relying on acronyms or proprietary terminology, founders must translate their innovations into benefits and solutions that resonate directly with their target market's existing understanding and pain points. This involves clearly articulating the problem being solved and how the product offers a unique, differentiated solution.
Ultimately, the session underscored that while AI can accelerate development, human-centric design remains indispensable. The ability to articulate value, maintain visual coherence, and guide user interaction with precision is not something that can be fully automated or overlooked. For startups in the AI domain, where innovation is rapid and competition fierce, a clear, intentional, and user-focused digital front door is not just good practice—it's a critical differentiator.
