In 2000, nine years after he joined Cargill Inc., David MacLennan felt his career had stalled. He was a top leader in Cargill's financial business, but he seemed pigeonholed as a finance guy, unable to move up in the company.
So he left, figuring he would never return. This was Cargill after all — the venerable Minnesota agribusiness giant still mostly owned by its founding families. Company leaders were almost always lifers, devotees to the Cargill creed.
"When I said goodbye, I thought this is it, they're erasing my name off any document I ever wrote — I never existed," MacLennan joked. More seriously, he said, in Cargill culture, "when the door closes, you're done."
But as the culture changed, the company rehired MacLennan in 2002 and put him on a new career path. On Sunday, MacLennan, 54, starts as Cargill's chief executive, only the ninth in the company's 148-year history.
He will pilot one of the world's largest privately held companies, with $137 billion in annual revenue, 142,000 employees and interests in everything from chocolate to road salt — all spread over 67 countries. He takes the helm as the corporate behemoth works to create a more nimble culture.
That means communications barriers in the Cargill bureaucracy must fall. It's a job that starts at the top, with the CEO either setting a regal tone or creating an atmosphere that invites questioning — without fear of getting slapped down.
"Part of internal transparency is having people come up to you and say "Hey, this is what I think is wrong — do you know about this?" rather than, "Oh boy, there's the CEO, I better not say anything," MacLennan said.
MacLennan, Cargill's chief operating officer, was named CEO in September to succeed Greg Page, who is retiring. Page, who played a key role in bringing MacLennan back to Cargill, will remain as the company's executive chairman.
