Vercel's Pranati Perry explains that tools like V0 occupy a new space between static design (Figma) and development. They enable designers and PMs to create interactive prototypes that better communicate intent, supplement PRDs, and explore dynamic states without requiring full engineering resources.

AI-powered "vibe coding" is reversing the design workflow. Instead of starting in Figma, designers now build functional prototypes directly with code-generating tools. Figma has shifted from being the first step (exploration) to the last step (fine-tuning the final 20% of pixel-perfect details).

To rapidly iterate on mobile UI, Lynn sketches screens on physical index cards, which have a similar aspect ratio to a phone. He then photographs these low-fidelity mockups and uses GPT-4's image generation to "upscale" them into high-fidelity designs, bridging the gap between physical brainstorming and digital prototyping tools like Figma.

When building his own site, MDS doesn't aim for pixel-perfect Figma files. He gets the design to 85% completion, establishing the core direction, and then moves to code to finalize details like hover states and animations where the interactive "feel" is paramount.

As a solo builder, you can't afford to perfect every UI element. Instead, identify the 20% of components that drive 80% of user interaction and obsess over their details. For the rest, use libraries and minimal systems to ensure consistency without getting bogged down.

Don't start designing landing pages in Figma. Begin with an unstructured "brain dump" of all copy, ideas, and data in a text document. First, organize this content into sections (Hero, Problem, etc.), then build the visual wireframe. This prevents design constraints from prematurely limiting your content strategy.

The co-founder, a designer, learned React to bypass the classic frustration of developers misinterpreting high-fidelity mockups. By designing directly in code, he maintains full control over the final UI, eliminates the handoff process, and saves significant time and back-and-forth.

Instead of building UI elements from scratch, adopt modern libraries like Tailwind's Catalyst or Shad CN. They provide pre-built, accessible components, allowing founders to focus engineering efforts on unique features rather than reinventing solved problems like keyboard navigation in dropdowns.

The founders avoid creating a rigid, atomized design system because the product is still iterating too quickly. They accept a "messy" component library and technical debt as a trade-off for speed. Formalizing a design system only makes sense once the product's UI has stabilized.
