Jerome Byers, head of Citigroup's small-business banking operations, is working to ensure that small-business owners know the bank is interested in helping them and gaining their business. "We have a 1,000-branch network in the United States that last year lent $7.9 billion to small-business owners. That's a great story. There are 260,000-plus customers in that network. We need to talk a little bit more about that," he said.
