The Trader Who Builds Billion-Dollar Companies: Tom Sosnoff on Thinkorswim, Tasty, and What Comes Next

Episode notes

Send us Fan Mail I sat down with Tom Sosnoff, one of the most successful entrepreneurs in financial services. Tom spent 19 years on Chicago’s CBOE trading floor and then left to build Thinkorswim, the first online broker specialized in options, which he sold to TD Ameritrade for $600 million. He then built Tastytrade and sold it nine years later for a billion dollars to IG Group. He is now building Lossdog, a career optimization platform to help fight wealth inequality. What I enjoyed the most of this conversation is how genuine Tom is. He’s kind and cares about fairness and inequality. Prioritizes legacy over money. And he is a builder at heart that loves to take risks. Want more podcast episodes?
