John, founder of the apparel company FUBU, explained to TV Insider in 2015 what he looks for in a Shark Tank participant: “My ideal formula is somebody who has failed a couple of times and kept going — that reduces the learning curve — and is in need of a couple of dollars and hopefully my guidance. If they expect me to run their entire business, that’s a turnoff. But I’m looking to be a mentor and partner.”

Herjavec, founder of the tech company Herjavec Group, talked about Shark Tank’s pandemic era in a TV Insider interview last year: “People could get loans back in 2009, but now, those same people may not get an investment if they’re not successful. That’s why Shark Tank is so great — people can get an investment. We can cut a ‘sharkier’ deal. People may need us more than they did a few years ago.”

“[The show] has come so far,” Cuban, co-founder of 2929 Entertainment and the majority owner of the Dallas Mavericks, told us in 2018. “There are so many great entrepreneurs, great businesses. And I think something which is just as important is the message we send to kids around the country that the American dream is alive and well. If the [people on the show can] start a business out of their garage or bedroom, so can you.”

“I know within 10 seconds — before anything is even said — whether an entrepreneur has what it takes,” O’Leary a.k.a. Mr. Wonderful, co-founder of SoftKey Software Products, told us in 2016. “I can see their level of energy or excitement or nervousness, and if they’re fortunate, it distills down to resolve. When they’re ready to work the room, you can just sense it.”
