Rapid Prototyping

Rapid Prototyping is the process of quickly creating a working model of a product or feature to test ideas, gather feedback, and iterate designs. It involves creating low to high-fidelity prototypes in a short timeframe, using tools like wireframes, paper models, or interactive digital prototypes. The goal is to speed up the design process while minimizing development costs.

Rapid prototyping compresses the feedback loop between idea and validation — instead of building something for 3 months and discovering it doesn't work, you test the concept in days. For founders under runway pressure, rapid prototyping is one of the highest-leverage practices because it prevents the most expensive mistake in product development: building the right thing in the wrong way, or the wrong thing entirely.

Dropbox's original 'prototype' was a 3-minute video showing a product that didn't exist yet — they uploaded it to Hacker News and got 75,000 email signups overnight. That rapid prototype (a video) validated demand before a single line of production code was written.
