When Brianna Gerber tells us that during earnings season at Mattel, Inc., she was once known as the investor relations person most likely to be “knocking on doors,” we can’t help but want to learn more about her IR tour of duty for the toy giant.  “I’d be calling on the marketing team and the commercial team, talking to treasury and tax, and asking them all ‘What’s really going on?’ because I would need to understand the numbers before I could explain them,” recalls Gerber, who occupied Mattel’s corridors for nearly five years, after having spent 10 years as an equity research executive.There’s little doubt here that Gerber is sharing a fond memory that exposes the somewhat immediate satisfaction that she experienced upon landing inside a corporate entity. The glass wall through which she had once peered as an equity analyst had vanished, and she was now able to engage one-on-one with the senior leaders best able to explain the complexities of the business.It’s a recollection that also reveals the door-opening presence that IR executives enjoy. Still, Gerber wanted something more, and while the IR career track at Mattel no doubt would offer her accelerated advancement, she instead decided to make a lateral move to Mattel’s FP&A team.“Ultimately, this was about me having the confidence in myself to say, ‘I understand the numbers and I understand why they tell a story, so I can now translate what I learned from this 30,000-foot view and use it to allow me to at the same time go even deeper,” remarks Gerber, who continued her career climb inside Mattel’s FP&A function for a number of years before being recruited by Kevin Farr, Mattel’s long-tenured CFO, who had exited the toy maker in 2017 to serve as CFO of ChromaDex, a pioneering biotech firm.At ChromaDex, with the two worlds of investor relations and FP&A under her purview, Gerber became a direct report to Mattel’s veteran CFO—a coveted opportunity for mentoring if ever there was one.  “I think that what brought Kevin here and what brought me here was in part the potential to build something,” comments Gerber, who would step into the CFO office at ChromaDex in August of 2022.Looking back on her career pivots from equity research to IR to FP&A, Gerber highlights her personal goal of seeking challenge.She adds: “I think that we are constantly reinventing ourselves, and this is what keeps our careers interesting.” –Jack Sweeney
