The marketing automation company Autopilot (formerly known as Bislr) has grabbed $7 million in new funding, according to a filing with the Securities and Exchange Commission Monday. It’s the fifth cash infusion the company has taken since 2011, and by far the largest, bringing its total up to $16.9 million.

San Francisco-based Autopilot makes a software program, also called Autopilot, that helps small businesses plan and manage marketing campaigns. Using Autopilot they can also build mobile-optimized websites, track marketing and advertising ROI, conduct email marketing, and manage social media marketing. It also pulls in campaign analytics data from Facebook Ads, Google Adwords, LinkedIn Ads, tweets, Facebook posts, etc.

Another Autopilot product, Prospect Ace, is a Google Chrome plugin that searches through social profiles (like LinkedIn) to find the email addresses and demographic data of sales prospects. Once a list of prospects has been collected, the data can flow directly into a marketing campaign in Autopilot.

Monday’s filing does not say who contributed to the new round, but Southern Cross Venture Partners, Timothy Draper, and Terry Garnett were involved in two separate funding rounds for the company during 2013.

Autopilot was founded by three brothers, Michael, Peter, and Chris Sharkey. The Australian serial entrepreneurs have launched several successful startups, including, which they sold to HomeAway for $220 million, according to Crunchbase.

Autopilot faces competition from Unbounce, ThriveHive, Hubspot, Glyder, Smore, and others.
