History.
Mutual Art was founded in 2004 by Moe Shniberg, an Israeli-born technology entrepreneur, David A. Ross, who was a former director of the Whitney Museum, and Dan Galai, a professor of business at Hebrew University. 
Mutual Art acted initially as a holding company for the Artist Pension Trust. 
In 2008 Mutual Art launched its online portal, mutualart.com. At the time, its web site was reportedly one of the first examples of the Web 2.0 Semantic Web applied to a customer service. The site attempted to link art collectors with artists, museums, galleries and information sources including the art publications, auction house information and prices.
In 2016 the company merged with the Artist Pension Trust to form the MutualArt Group.
