Lance Armstrong

Thomas Weisel is a legend in finance and Silicon Valley. He was the banker behind Yahoo’s public offering and some of the biggest deals during the dot-com bubble. He famously sold the firm he ran, Montgomery Securities, for $1.2 billion in 1997. And he sold his next firm, Thomas Weisel Partners, for $300 million to Stifel Financial in 2010. But it is Mr. Weisel’s extracurricular activity that connects him to the news of the moment: he was Mr. Armstrong’s biggest financial backer and the single individual most responsible for the money machine that propelled Mr. Armstrong’s career…For Mr. Weisel, the team and Mr. Armstrong were an all-consuming passion. He would go every year to the Tour de France and at times travel in the team’s pacer car, occasionally yelling instructions to Mr. Armstrong over the radio system. [Dealbook]
