Most inventors build their prototype wrong. Not because they're not smart — but because nobody told them that a prototype isn't a miniature version of the final product. It's a tool for answering a specific question. And using the wrong tool for the wrong question is one of the fastest ways to waste time and money in product development.
Prototype Like a Pro teaches you to build with purpose. You'll learn which prototyping method to use at each stage, how to test with real users (not just your friends), when to stop iterating and commit, and how to get from prototype to a production-ready product without losing your mind or your budget.
Whether you've never built anything before or you're an experienced maker looking to tighten your process, this guide gives you a practical framework and a full toolkit to work from.
Written by the makers at Redtail Innovations, who build prototypes for inventors and product companies every day.
