If you have ever wanted to own one of Lady Gaga’s costumes, play golf with President Bill Clinton, or be participate in a private Papal audience at the Vatican, Charitybuzz.com can make that happen. Assuming you are willing to pay, that is.

The company holds online charity auctions to make money for non-profits, and for itself. Many celebrities are willing to sell their possessions and time for causes they believe in, and Charitybuzz provides a platform that brings them together with charitable organizations to do this. It generates revenue by retaining 20% of the sales from the auction.

In order to launch a mobile presence, expand its market share, and grow the team, it has raised $3 million in a second round of angel funding.

Charitybuzz was founded in 2005 by CEO Coppy Holzman, a successful businessman who made his career building e-commerce company Webvan.com. Since then, Charitybuzz has partnered with more than 1,300 nonprofits and raised more than $60 million for social good, leveraging the power of celebrities, influencers, and major brands.

The star-studded list of participants is comprised of famous figures from across music, film, politics, sports and the business world. Jay-Z, Lady Gaga, Justin Bieber, George Clooney, Lance Armstrong, Richard Branson, Donald Trump, Oprah and Bill Clinton have all auctioned something off on Charitybuzz.

Causes include UNICEF, Breast Cancer Research Foundation, St. Jude’s Children’s Research Hospital, the Children’s Health Fund, Boys and Girls Clubs, and the Humane Society. Major brands like Ralph Lauren, People Magazine, Chevrolet, and Mattel have also participated.

This brings its total funding to $5 million. The team is based in New York.

While discussing which dream experiences we would select, if either of us had a few thousand dollars to donate to charity, VentureBeat writer Meaghan Kelly and I differed. She would opt for a set visit to The Office, while I would buy tickets to a Diane Von Furstenberg fashion show.
