Sales research startup Mattermark raises $7.3 million, now valued at $42 million

Mattermark, which has evolved rapidly from a database to help investors rank startups into a sales intelligence service, today announced that it has raised $7.3 million in series B funding and is valued at $42 million. The equity investment was led by Foundry Group and Jon Hallett, with participation from existing investors. (Disclosure: VentureBeat occasionally publishes opinion pieces from Foundry Group’s Brad Feld.) Total funding to date is $18.4 million.

According to cofounder and CEO Danielle Morrill, “we’ve evolved a lot from our ‘Bloomberg for Startups'” origins, and the startup is finding success with its sharpened focus.

Based in San Francisco, the three-year-old Mattermark now has 50 employees; 500 customers drawn from the ranks of large corporations, private equity, and sales and marketing firms; and is generating $300,000 in monthly revenue, according to a company statement. The company will use the investment to build out its sales force and continue creating what it calls “an un­killable SaaS company.”

Mattermark’s service offers one­-click integrations with a wide range of sales tools, like LinkedIn and Salesforce; spreadsheets, like Microsoft Excel and Google Sheets; and an API for software developers to write custom solutions that tie into the Mattermark platform. Mattermark’s customers use the service for lead discovery and qualification, detailed company information, as well as up-to-the-minute data on a prospect’s brand footprint and employee headcount trends.
