B ill Stone is the founder, chairman, and CEO of SS&C Technologies, a global provider of investment and financial software-enabled services. He launched the company in 1986 in his basement in Connecticut with just $20,000 in savings from his previous job at KPMG. Stone built SS&C into a fintech giant by acquiring over 50 companies, aggressively expanding its capabilities in fund administration, wealth management, and insurance software.

He has taken the company public twice, first in 1996 (privatized in 2005) and again in 2010. Known for his hands-on leadership style and deal-making prowess, Stone has grown SS&C's annual revenue to over $5 billion. He remains the largest individual shareholder, and his journey from an accountant to a billionaire tech mogul is a classic American success story. He is also a dedicated philanthropist, supporting education and healthcare in his home state of Indiana.
