Andrew Stevenson built his career as an operator rather than a career investor, starting as Redwood Materials' first full-time employee and helping take it from nothing to a round-the-clock processing facility in under four years, then leading sales, project development, and policy at Twelve, where he helped narrow the company's focus to sustainable aviation fuel and used relationships with customers like Alaska Airlines and Microsoft to build demand. He backs this hands-on experience with an unusual mix of early climate policy work, including attending COP in 2008, and specific operating views, such as favoring salary and equity over early commission plans for sales hires, and he's known among former colleagues for combining strong execution with a low-ego style.
