Perpay

Chris DiMarco is no stranger to the Inc. 5000. Before he founded Perpay, the Philadelphia-based fintech company he launched in 2014, he led Lamps.com to fast growth. The online lighting retailer landed at No. 161, after growing its revenue 2,473 percent to $3.4 million in 2015. His current company has grown by offering products for a very specific customer: credit-challenged consumers. At Perpay's Amazon-style shopping site, users can buy items from brands like KitchenAid and LG--basically anything you can find at Best Buy or Walmart, DiMarco says. They pay off the purchases over time--and interest free--with deductions from each paycheck. --Cameron Albert-Deitch
