WorkHound, the software app that allows truckers to lodge complaints on the fly, raised $500,000 in a recent round led by Right Side Capital Management out of San Francisco. Also investing were Dynamo Fund out of Chattanooga, Tenn., Des Moines-based Twelve19 Ventures, and multiple angel investors. The app helps companies connect with workers, which helps with workforce retention and customer satisfaction, the company said. Workforce employs four in Chattanooga and two in Des Moines.
