“In 2019 on his 75th birthday, he stepped down as CEO, but retirement is out of the question. He's 81, chairman of Interactive Brokers, still owns nearly 70% of the business”

“A pure play brokerage with four million customers, over seven hundred billion in client assets, and just 3000 employees, most of them engineers. In 2024, it generated 3.7 billion in profits on 5.2 billion in revenue. The company he took public at a twelve bill…”
