ProProfs, a provider of SaaS products, completed the acquisition of Qualaroo, a survey software provider, from investors Polaris Partners, First Round Capital, True Ventures, Okapi Venture Capital, 500 Startups and Scaleworks Associates. Financial terms were not disclosed. "We have been building our survey tools since 2012, and are excited to add Qualaroo's unique functionality to our portfolio.
