With $260 million worth of investments and a $2.5 billion, it’s a big job. But Carbon’s 500-person headcount is small potatoes compared to Ellen Kullman’s last gig. > For six years, Kullman headed up DuPont, the culmination of a nearly 30-year career at the chemical giant. After leaving the role in 2016, she joined a number of different boards, including Goldman Sachs and Dell. It was, however, a three-year-old Bay Area-based 3D printing company that ultimately drew her interest.
