The San Francisco-based firm was joined by DAG Ventures and existing investors Matrix Partners and Eden Ventures in the Series C round.
Huddle said it planned to use the capital to help continue the growth which has seen it triple in size each year since it was launched in 2007.
The financing takes the total equity raised by the company to $40m.
Huddle’s software allows organisations to securely store, share and collaborate on content in the cloud on any device, with teams both inside and outside of the firewall.
Jafco general partner Tom Mawhinney said, “The intelligence in Huddle’s content collaboration software helps people and organizations discover valuable information that they never knew existed.
“We see intelligent features becoming as important, if not more so, than social features and we’re delighted to be supporting a company that is revolutionizing enterprise technology.
“Huddle’s strong, entrepreneurial team has already ensured that the company has gained significant momentum in the marketplace and I’m looking forward to the next stage of the company’s expansion.”
Jafco Ventures is the US subsidiary of Japanese private equity firm Jafco, which provides it with between $100m and $150m every two years for a new fund and provides access to the Japanese market.
