Which guest shark on Shark Tank founded the lifestyle brand Skinnygirl?

Bethenny Frankel founded the lifestyle brand Skinnygirl and later appeared as a guest shark on Shark Tank.

Skinnygirl began as a brand associated with low-calorie cocktails, particularly Skinnygirl Margarita. Frankel launched the cocktail business in 2009, and Beam Global acquired the spirits brand in 2011. Frankel retained rights to develop Skinnygirl products in other categories, allowing the name to expand beyond beverages.

Frankel’s Shark Tank appearances are distinct from those of the show’s regular investors. She is also known for appearing on The Real Housewives of New York City and for founding the disaster-relief initiative BStrong. Skinnygirl should not be confused with Spanx, the shapewear company founded by fellow guest shark Sara Blakely.
