Jim McKelvey – $3.3 Billion

Jim McKelvey came into the business scene through Square. After creating and working for the financial company, he sought a change of pace and became the Federal Reserve Bank of St. Louis’s director. All these ventures swelled the billionaire’s bank balance and made McKelvey an affluent entrepreneur.

However, Jim is more notable for his philanthropy work. The otherwise capitalist owns a Nonprofit organization named LaunchCode. He has also made massive donations to different organizations, making him one of the precious few businessmen who have given back to society so generously! Way to go!
