Hubspot announced Tuesday it secured a $32 million Series D funding round from Google Ventures, Sequoia Capital, and Salesforce.com.

HubSpot Cofounder Brian Halligan wrote in a blog post the company plans to invest in research and development that supports "inbound marketing," which taps optimized search web content and applications.

The $32 million round adds to the $33 million the company raised in three earlier funding rounds from the likes of deep-pocked VCs. Among them General Catalyst, Matrix Partners and Scale Venture Partners.
