UI/UX design · How Founders Use AI
Why prototype with AI before hiring a designer?
Because a working prototype beats a pitch deck and a job posting: in an afternoon you can put a clickable version of your idea in front of real users, sharpen your spec, and find out what is worth building before spending a rupee on salaries. A quarter of YC's Winter 2025 batch shipped codebases that were almost entirely AI-generated, and product leaders now treat prompt-built prototypes as the new PRD: you build to think before you build to ship. A designer is still worth hiring, but later, when you have signal and need craft and consistency, not to produce your first draft.
