The Parasol Family – $1B
PartyGaming and PartyPoker are massive gaming empires which have given the Parasol family their enormous and jaw-dropping fortune. Ruth Parasol worked as an engineer prior to starting her online casino back in the late ‘90s. It operated in the Caribbean at the time, but when it got successful really quickly, it was rebranded and became PArtyPoker.com, which soon started netting over 500 million dollars in revenue every year. In 2014, the family’s net worth suffered due to a federal investigation and Parasol’s divorce from her husband.
The Golisano Family – $3.1B
Young business owners are probably familiar with the company Paychex, which is one of the leading payroll service providers in the country. In the early 1970s, Tom Golisano founded the company with only a few thousand dollars and just within the decade, it became extremely successful, reaching the $2 billion mark in 2010. Golisano no longer runs the day-to-day affairs of the company, but owning majority stakes in sports teams, such as the Buffalo Sabres and the Buffalo Bandits did keep him busy for some time. The Golisano family still donates millions to charity every year.
