In 2014, I served as executive vice president for Cricut, a small company that manufactures personal electronic cutting machines for creative design. At the time, the company was struggling. Once an industry leader, it was being outpaced by competitors, and it was my job—along with senior management's—to turn things around. We needed to do more than rebrand; we needed to think and act more like a startup. That's a familiar solution to a familiar problem that once dominant companies face. Earlier this year, Samsung announced a major push to reinvent its culture in the startup mold. That isn't easy to pull off, though, and unfortunately, our initial changes at Cricut fell flat.
