Invaluable, the world’s leading online marketplace for fine art, antiques and collectibles, announced today that it has signed the 5,000th auction house to its global marketplace.

The milestone was reached after a strong 2016 that saw the Boston-based company sign 575 auction houses to the Invaluable marketplace, joining the nearly 400 art dealers and galleries also listing with Invaluable. Year to date for 2017, Invaluable has signed more than 200 additional auction houses, bringing the total to more than 5,000. The company now hosts more than 16,000 auctions per year and has 3 million unique visitors a month.

“Signing 5,000 auction houses from more than 50 countries around the world is an impressive accomplishment that shows we’re delivering value to our auction house partners. We’re very proud of that,” said Invaluable CEO Rob Weisberg. “The art and auction business is irrevocably changing. While overall auction house sales globally were down last year, online art sales were up 15 percent according to the 2017 Hiscox Online Art Trade Report. All signs point to significant continued online growth in the years ahead.”

Online sales powered by Invaluable reached $300 million in 2016, Weisberg said, up dramatically from $48 million recorded when he joined the company in 2012.

In tandem with this milestone, the company announced it is hosting the inaugural 2017 Global Auction House Summit in Boston from Sept. 6-8, 2017, at The Boston Park Plaza Hotel. For the first time ever, Invaluable is bringing together leaders from top auction houses and industry experts at an invitation-only event to discuss trends, best practices and common obstacles and to help define the future of the industry.

“An event of this magnitude has never been done before in the art and auction industry, so it’s something we are very excited about. We have commitments to attend from some of the top auction houses in the world, including Sotheby’s, Phillips and Bonhams. We’re planning on a full agenda that will focus on the auction house of the future,” continued Weisberg.
