Login technology vendor Janrain has raised $27 million in a Series D funding round.

Venture capital firm HighBar Partners led the round, which included existing investors Millennium Technology Value Partners, Split Rock Partners, Epic Ventures, Emergence Capital, RPM Ventures and DFJ Frontier.

Janrain, which announced the funding round today, plans to use the financing, in part, to develop user engagement analytics that could help retailers and other businesses better understand the consumers who use Janrain’s technology to log into their sites and apps. Janrain provides technology that enables businesses to offer consumers to sign into sites using the credentials they’ve established with Google Inc., Yahoo Inc., as well as a number of social networks.

“We see our core customer identity platform as the clear leader in a rapidly growing market,” says Larry Drebes, Janrain’s founder and CEO. “The organization today is structured to serve that market efficiently, which then allows us to look at adjacent problems and areas of expansion.”

Janrain, which is one of 1,737 vendors profiled in the Internet Retailer 2016 Guide to E-commerce Technology, says it has more than 2,000 customers in over 70 countries.
