uTest, a crowdsourcing company that does in-the-wild mobile app testing, has just finished a strong series C investment round raking in almost $13M. The round has been lead by their primary investor, Scale Ventures, but past investors also participated – such as Longworth Partners, Egan-Managed Capital and Mesco Ltd.

From their blog post on the subject, they intend to use the funds to make numerous expansions to their current paradigm, including: “expanding our newly launched usability testing and load testing services; moving into new service categories that help companies launch great apps; turning our testing platform and APIs into the industry standard for managing internal and external testing teams; engaging our community of 30,000 professional testers; growing mind share and market share of our in-the-wild testing services.”

The company, launched in 2008, has managed almost exponential growth and consumer reach. They present an interesting product for app developers and publishers by giving them access to a vast pool of quality assurance testers—in excess of 25,000+ professionals, according to their About Us page—and the reliability of having their apps tested under real world conditions. They cater to both Fortune 500 companies and garage start-ups, giving them a giant range of engagement and management.

This sort of influx of cash will probably not just serve them well, but the entire app community, which could always use a little bit more help in enhancing the quality of apps before they reach the marketplace. We included uTest in a case study last year: check it out here.
