Southern Bancorp, a community development financial institution in Arkadelphia, Arkansas, is using an infusion of cash from Square to develop niche digital banking services for segments of its customer base. Square made a multimillion-dollar investment in Southern as part of a larger $100 million pledge to support minority and underserved communities, the bank announced this month. With this funding, Southern intends to create customized apps, each designed to address a specific situation for a well-defined underserved group. “We think the true growth opportunity for our bank is digital,” said Darrin Williams, Southern's CEO. “We’re very excited Square took note of the work we do. That capital will allow us to reach deeper into underserved markets.”
