Loops

Building Products with Clarity & Confidence

Available in paperback, Kindle, and audiobook.

What's this all about?

You have to build things with limited time and a limited budget. How do you make the most of both? Not only that, how do you get confidence and clarity in what you're going to build and how you're going to build it? Whether you're a startup founder or the head of a corporate product team, you need the right strategies and tools to give your team the best chances of building products and services that give you a competitive advantage.

Loops is the practical guide you need to get products out of your mind's eye and into the real world. Seasoned product strategist and experience designer J Cornelius covers the processes, exercises, and methodologies used by some of the world's fastest moving and most successful startups and corporate product teams to get out in front and stay there. This book will give you the tools you need to create products people love.

Three phases. Five steps. One clear process.

Most product failures aren't caused by bad ideas — they're caused by bad process. Teams skip research, fall in love with solutions before understanding problems, and build things nobody asked for.

Loops fixes that. It's a flexible, iterative framework that moves you from uncertainty to confidence through structured experimentation. The kind of process that works whether you're a startup founder or a product leader at a Fortune 500.

"J has helped us deliver amazing value to our customers time and time again. His ability to take nebulous concepts and drill down until they become quality products is second to none."

Adam Ferrando — Delta Air Lines

"Few have logged as many hours as J, thinking deeply about product design and the methodologies that lead to success. This book captures years of wisdom that's sure to set you on the right path."

Aarron Walter — VP of Design Education at InVision
