Demo: Spec-Driven Prototype Limitations

Ravi Mehta, now a product advisor, has built and scaled products used by millions. His past roles include Chief Product Officer at Tinder, Entrepreneur in Residence at Reforge, and senior product leadership positions at Facebook, TripAdvisor, and Xbox. In this episode, Ravi demonstrates his data-driven approach to AI prototyping that produces dramatically better results than traditional "vibe prototyping." He also shares his structured framework for generating professional-quality images in Midjourney that look like they were shot by a professional photographer.

What you’ll learn:

1. Why most product managers and designers are “vibe prototyping” with AI and getting mediocre results
2. How to use JSON data models instead of design systems as the foundation for better AI prototypes
3. A simple three-part framework for structuring Midjourney prompts to get professional-quality photos
4. How to use Claude and Unsplash’s MCP server to generate realistic data and images for your prototypes
5. Why real data (not Lorem Ipsum) is critical for getting meaningful feedback from stakeholders
6. The film stock “cheat code” that instantly elevates your AI-generated photos
