“If you want to know where to go after a Design Sprint, Beyond the Prototype shows the way. Douglas’ expert guidance—grounded in his experience as a founder, CTO, startup advisor, and master facilitator—anticipates the challenges teams face when building something new.” —Jake Knapp, inventor of the Design Sprint and New York Times bestselling author of Sprint

“I work with so many companies excited about their first Design Sprint that then ask: ‘Now what?’ Douglas’ book is the great advice they’ve been looking for.” —Jeff Patton, Author of User Story Mapping



Douglas Ferguson is an Austin-based entrepreneur and startup advisor. After serving as CTO at multiple Austin tech startups, Douglas launched Voltage Control, an agency that specializes in helping companies achieve their full potential. Voltage Control works directly with companies to design customized, collaborative workshops that jumpstart new projects and products. 

While serving as CTO at Twyla, Douglas worked with Google Ventures to run Design Sprints for understanding consumer behavior, and he now brings this process-based experience to solve many types of problems across a wide array of industries around the world. 

Douglas recently released his first book, Beyond the Prototype, which details a tangible, 6-step plan to help organizations move from idea to finished product. When he’s not working, Douglas can be found patching together his modular synthesizer, playing guitar, or watching documentaries.



Most companies have lots of ideas on their hands. But projects often fall into a slump following the prototype phase. Beyond the Prototype is for people who want to move forward with a critical project. Oftentimes, things get in the way and projects get pushed to the side before crossing the finish line. The book—filled with case-studies from organizations both big and small—serves as a guide to jumpstarting a project down the path of execution. Born out of the Design Sprint process, Beyond the Prototype presents a tangible 6-step plan to help teams bridge the gap between idea and execution.
