If you try to avoid risk, you actually risk total failure. Or worse: mediocrity. Take it from Shellye Archambeau. She led the most stunning Silicon Valley turnaround you’ve never heard of. She took the role of CEO for a failing tech company, months from bankruptcy. Through a series of calculated risks, she led it through a complex merger, a head-spinning pivot, and grew it into MetricStream, which now boasts 1,200 employees and a valuation in the hundreds of millions. How? Clear goals and big risks — the same principles that have defined her career. With a cameo appearance by champion poker player Liv Boeree.
