A new group of private equity firms have invested $15 million in financing into The Resumator. This Series C financing round brings the company’s total funding to date to $18 million.

Co-headquartered in Pittsburgh and San Francisco, the Web-based recruiting and hiring software company this week said the new financing round will be used to penetrate even deeper into key markets, expand data and engineering teams, and develop new products and partnerships.

Existing investors Rincon Venture Partners and Birchmere Ventures participated in the round, joined by new investments from Blue Cloud Ventures, Riverfront Ventures and Volition Capital, the round’s lead investor.

“Recruiting is no longer about fighting the ‘workflow war’ or finding inventive ways to streamline hiring — it’s about helping teams quickly identify and hire great talent consistently and predictably,” The Resumator founder and CEO Don Charlton said in a statement.

The company said its software-as-a-service (SaaS)-based recruiting platform now supports more than 2,200 customers in 63 countries across technology, media and entertainment industries.

The Resumator received $2.1 million in Series B funding in October 2012, with Salesforce.com contributing funds to the financing round.
