Jamie Siminoff's first run as founder pitching his business on ABC's "Shark Tank" in 2013 wasn't what he'd hoped: He walked away empty-handed after rejecting what he saw as a weak offer from Kevin O'Leary. But Siminoff returned as a guest judge for season 10, because his company Ring went on to huge success — first billionaire Richard Branson became an investor and thenAmazon bought Ring for $1 billion in February 2018.
"My pinnacle of success, I thought, was getting on the show as an entrepreneur. So to be able to come back as a Shark is a beyond surreal thing," Siminoff told CNBC Make It in October, when he returned to the show for the first time.
Siminoff, who was back in the Tank as a guest investor on Sunday's episode, also spilled "Shark Tank's" behind-the-scenes secrets to CNBC Make It.
