Causes, a company that helps Facebook users donate to charitable organizations, raised $9 million in funding from New Enterprise Associates, Founders Fund Management LLC, Ron Conway and Marc Benioff. This latest round of funding brings Causes’ total financing to $16 million.

As we reported previously, Causes started selling charitable donation gift cards in $25 and $50 denominations at Safeway and Vons grocery store locations in California recently. The cards are a way to give a charitable gift that allows the receiver to select to which charity to donate.

Causes makes money by asking for a voluntary tip of 10%-plus on transactions.

Bloomberg reports that Causes’ Facebook application connects 119 million people to its more than 1.5 million charitable causes. Our AppData service shows that Causes currently has 26.7 million monthly active users and 1.4 million daily active users.

The app allows Facebook users to rally friends for donations but its birthday function, where the person with the birthday asks friends for a gift to their favorite cause,, has been used by 100,000 people totaling $7.6 million, according to the report. The company also has corporate partnerships and in January, Causes began to power the Facebook Charity Gift Shop.
