  • Rapid Validation Prompt:

    “Write a design prompt for a prototype that helps validate a new idea for remote team collaboration. Include the core hypothesis, user persona, and what success looks like.”

Founder tip: Tweak these prompts to fit your current product sprint, investor pitch, or user segment. ChatGPT will adapt—just add your context.
