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 keep pace with AI development, the barrier between design and engineering must fall. Intercom made it a non-negotiable job requirement for every product designer to ship code to production. This empowers them to fix UI bugs directly and accelerates the entire development cycle.

With advanced AI coding tools and a robust design system, Snap's engineers build functional prototypes so quickly that the traditional design-first workflow is inverted. Instead of waiting for Figma mock-ups, teams now build and show working code to decide which ideas win.

Instead of creating static mockups in Figma, Cursor's design team prototypes directly in their AI code editor. This allows them to interact with the "life states of the app" and get a more realistic feel for the product, bridging the gap between design and engineering.

To maximize speed, V0 operates with a "no handoffs" philosophy. Everyone, including designers and product managers, is expected to contribute code and submit their own pull requests. This "full-stack PM" model minimizes the coordination costs and wasted cycles of explaining changes.

Instead of getting bogged down in production constraints like failing tests, designers are encouraged to use code to render the most desirable version of an idea. The prototype's value is in communicating the full vision to engineering, not in being a mergeable pull request.

A designer's time allocation has radically changed. Where mocking and prototyping once took 60-70% of their time, it's now just 30-40%. The majority of their time is now spent collaborating directly with engineers and contributing to implementation and code.

Over 90% of Cash App's design org now ships production code, a transformation enabled by internal code fluency programs. This blurs the lines between roles, creating a new "builder" archetype who can take ideas from concept to launch independently.
