Online lending provider Elevate is helping millennials boost their credit scores. Ken Rees, CEO of the company, says attracting new customers has been easy, because the market with bad credit options is large and underserved. Rees says Elevate is trying to be a lender for the millennial generation, a group that might not have the most pristine credit history. The company went public last spring, and generated $3 million in net income for the latest quarter.
