Over the past few years, Tumblr, a microblogging service, has steadily built a community of fans and users who like the site’s combination of social networking features and simple blogging tools that lets them quickly post photographs, videos, songs, links and bits of text.

Now, the company has attracted a slew of venture capitalists who are hoping to capitalize on that popularity.

On Monday, the company will announce it raised $85 million in fresh financing. The round was led by Greylock Partners and Insight Venture Partners, and the Chernin Group, Richard Branson, Spark Capital, Union Square Ventures and Sequoia Capital also contributed. To date, the company has raised roughly $40 million in funding.

David Karp, who founded the company in 2007, said in a news release that the extra money “allows us to continue to scale our business and give real focus to the further development of Tumblr.”

Mr. Karp said that Tumblr’s growth has exploded in the past year. It’s attracted popular musicians such as Lady Gaga and traffic leapt to 13 billion page views per month from 2 billion page views per month. Since the site was first introduced, 30 million blogs have been created using the tool. Those 30 million blogs now generate more than 40 million posts each day.

A recent report from Nielsen said that the audience for the site tripled in the past year and has drawn more female teens to the site than any other social network. Although Facebook still dominates the majority of the time Americans spend on the Web, occupying more than 53 billion minutes each month, Tumblr manages to capture a reasonable share of screen time as well, with more than 623 million minutes per month.

“Tumblr has come far since we began our journey,” said Mr. Karp. “From the early users signing up to easily share all of the things they cared about, to the global community today where creators have an incredible opportunity to reach an audience of hundreds of millions, it’s been a remarkable four years.”
