The data from Lenny’s Newsletter’s AI productivity survey showed PMs ranking prototyping as their #2 use case for AI, ahead of designers. Here’s what that looks like in practice.
Figma is now teaching PMs to build prototypes instead of writing PRDs. Using Figma Make, product managers can go from idea to interactive prototype without waiting on design. Emma Webster writing in Figma’s blog:
By turning early directions into interactive, high-fidelity prototypes, you can more easily explore multiple concepts and take ideas further. Instead of spending time writing documentation that may not capture the nuances of a product, prototypes enable you to show, rather than tell.
The piece walks through how Figma’s own PMs use Make for exploration, validation, and decision-making. One PM prototyped a feature flow and ran five user interviews—all within two days. Another used it to workshop scrolling behavior options that were “almost impossible to describe” in words.
The closing is direct about what this means for roles:
In this new landscape, the PMs who thrive will be those who embrace real-time iteration, moving fluidly across traditional role boundaries.
“Traditional role boundaries” being design’s territory.
This isn’t a threat if designers are already operating upstream—defining what to build, not just how it looks. But if your value proposition is “I make the mockups,” PMs now have tools to do that themselves.

Prototypes Are the New PRDs
Inside Figma Make, product managers are pressure-testing assumptions early, building momentum, and rallying teams around something tangible.
