Veracode, a software as a service application security provider, announced today that it had secured $30 million in new funding from  Meritech Capital Partners and existing investors Atlas Venture, .406 Ventures, and StarVest Partners.

The funding will allow the Waltham-based company to continue to hire aggressively, according to a release. Veracode plans to double its headcount by the end of 2012.

“Our momentum is significant—we achieved over 150% year-over-year growth, built-out the team by 30% including the addition of key executives, and now have added the backing of an iconic investor to fuel our expansion,” said Bob Brennan, CEO of Veracode.

The company had previously raised a total of $42 million, the most recent of that being $12.3 million in 2010. Rumors of this latest round were reported by The Boston Business Journal in March.

“The need to secure applications is increasingly obvious, and Veracode’s approach to solving the problem allows its customers to achieve instant application security,” said Rob Ward, Managing Director at Meritech Capital Partners.  “Our investment demonstrates our confidence in the market and is intended to accelerate Veracode’s already impressive growth.”
