We often like to ask our CFO guests if they remember the first time that they presented to a board of directors. For many, this happened earlier than you might expect—but few of our interviewees have exposed the benefits of “early access” for us better than Rex Jackson.“I grew up in boardrooms,” comments Jackson, who recalls being invited to his first board meeting when he was about 28.Jackson had spent 3 years at a Los Angeles law firm before signing on as a corporate attorney for a local real estate management company whose board had a budding appetite for M&A.  “For any deal that they wanted to do, I became the ‘Get It Done Guy,’” explains Jackson, who notes that his moniker in the boardroom soon began to apply to more than just M&A.“When an opportunity to land on a clear track northward within an organization presents itself, you just jump all over it,” remarks Jackson, whose early career endeavors swung open the door to a succession of general counsel roles at a variety of companies.Along the way, his “get it done” mantra helped to add some noticeable addenda to his legal career track.Jackson explains: “One time, I ended up as a salesperson; another time, I had to head up marketing. I have run R&D, I have run operations, I have run corporate development.”  It perhaps should come as no surprise, then, that when an interim CFO position opened up at publicly-traded Synopsis, Jackson—then the firm’s general counsel—shot up his hand. While he would occupy this particular role for no more than a year, within 13 months of concluding this interim tour of duty he was stepping into a CFO position at yet another publicly-traded company.Just as at Synopsis, Jackson’s next chapter began with a CFO exit.“Within 6 weeks of my arrival as a new general counsel, the company shot their CFO,” reports Jackson, who subsequently was asked by the company’s board to move into the CFO role. This time, Jackson would occupy the office for roughly 3-1/2 years.“It was at this point that I became visible on recruiter radar screens,” comments Jackson, who has to date served as CFO at four other companies, including ChargePoint, where he has been CFO for the past 5 years.Says Jackson: “I’ve had good support from CEOs and board members, and if you can get this kind of access and observe the business from a high level, then finance—since it’s horizontal within the business—will serve you well.” –Jack Sweeney
