Kevin O'Leary likely made over 20 times his money on a single "Shark Tank" investment.

The celebrity investor backed Basepaws, a startup selling at-home genetic tests for cats, when it was pitched on "Shark Tank" in 2019. Its founder, Anna Skaya, was seeking $250,000 in exchange for a 5% stake in her company. O'Leary and another shark, Robert Herjavec, both agreed to invest $125,000 for a 5% stake each, valuing Basepaws at $2.5 million.
