Three years ago, I was in a predicament. I was in a Startup Accelerator (which is a business program for startups, which usually ends with you pitching your idea to investors), and pivoted very early in the program. Problem was, I was neither a coder nor designer. I was just a guy with an idea for a business. The idea of sitting in front of an investor-many whom likely wouldn't be the most tech-savvy people-and trying to explain the idea was daunting. In writing, there's an old phrase: show, don't tell. But how do you show something when you have literally hours before meeting with someone who could potentially give you the funds you need to succeed? In a word: Sketch Sketch gave me the ability to quickly mockup my idea so that when I met with investors and advisors, I wasn't telling-I was showing them. And they were impressed. It clicked with them more than words could. Many believed that what they were seeing was already done and working. If you are a non-coder, non-designer like me, then is book will give you the foundation you need to create your software or app.
