Miami University graduates Selom Agbitor and Oliver Zak, founders of a line of tattoo-care products, return to ABC’s “Shark Tank” at 8 p.m. Oct. 14.

Agbitor, of Columbus, and Zak, of Cleveland, graduated in 2019 and founded Mad Rabbit, “the clean and natural tattoo skincare brand,” according to a press release. 

The original episode featuring their company aired March 26, 2021, where the brand landed $500,000 for a 12% stake from Mark Cuban. Since then, Mad Rabbit has tripled its revenue and expanded its retail presence.
