Allison Gelb
Mark Pincus helped found Zynga during the early days of Twitter and Facebook. Today, he has about $1.2 billion to his name. In 2008, he married Allison Gelb, and she would go on to create One Kings Lane, an online store that sold furniture and accessories. The company was eventually purchased by Bed Bath & Beyond in 2016.
After roughly nine years of marriage, the tech billionaire and his wife called it quits. They have three children together, and both fought to gain custody of their children. Since he was a billionaire before their marriage, all of his assets were protected by the prenup, which she fought tooth and nail to nullify.
