A little more than 13 years ago, when Nathan Feather joined PrimeRevenue–an upstart supplier of supply chain financial services–the 20-member enterprise was just signing up its first direct customers. “We were a complete finance function spanning a person and a half,” explains Feather, who says that despite its sparse resources, finance was from time to time drawn into addressing legal, HR, and IT-related matters. This was what any C-suite executive might expect inside a start-up enterprise, but Feather is not your typical start-up CFO. Put another way: He’s not a serial CFO–the singular species that frequently arrives in the start-up’s C-suite already eyeing a transaction. For Feather, PrimeRevenue was an opportunity to perform an act of creation–one in which the company’s business functions, still in their infancy (or yet to be established), would rely in part on his judgment and ability to see into the company’s future. “We built out the accounting and controllership side of the house first and then built out FP&A,” says Feather, who frequently uses house-building metaphors when describing the evolution of the business. As PrimeRevenue grew, Feather’s appetite for learning all aspects of firm-building was once more revealed when he moved to Prague, where in addition to his finance leadership role, he took on that of general manager, Europe. “I had had some experience in supporting sales and operations, but I had never led them, so this role really allowed me to see beyond finance,” recalls Feather, who after 13 years of firm-building appears little eager to remove his lens from PrimeRevenue’s future. —Jack Sweeney
