With a minimal marketing budget (SG&A is just 5% of revenue), Interactive Brokers has achieved 30%+ annual account growth.

Owning nearly 100% of his cash-flow-positive company, Tomas Peterffy took Interactive Brokers public purely for advertising purposes. He viewed the IPO as a way to get "the company's name in the public domain" and even used a Dutch auction to save $80 million on banking fees.
