IfOnly is a marketplace that offers thousands of unique experiences with local and world renowned luminaries. Each experience purchased benefits a worthy cause. Locals and travelers can enjoy amazing experiences in San Francisco, New York, Los Angeles, Boston, Chicago, Miami, Vegas and beyond. Luminaries can share their talent and build their business on the IfOnly marketplace. IfOnly was founded in 2012 and is backed by American Express, Sotheby's, Conde Nast, Khosla Ventures, NEA and other top tier investment partners. IfOnly was acquired by Mastercard and became Priceless Cities in late 2019.
