FORTUNE — As the youngest-ever vice president and general manager of GMF Robotics, the industrial robotics division of automaker General Motors, Keith Krach used his early momentum in tech business to help found Rasna (which was sold in 1995 to Parametric Technologies for $500 million) and Ariba. He continued his entrepreneurial path by joining DocuSign — an electronic signature company that facilitates legal, contractual, and tax documents online — and becoming the company’s chairman and CEO.

Krach holds a BS in industrial engineering from Purdue University and an MBA from Harvard, and he sits on several boards, including Angie’s List and Purdue University’s board of trustees. We asked him about his early days in business and what he considers to be his biggest achievements, as well as the thrill-seeking he does in his free time.
