Mark Cuban never held back on Shark Tank, but this time, his frustration hit another level. A weight loss product waltzed in, promising miracle results, but Cuban wasn’t buying it. He called it out instantly, shutting down the pitch with brutal honesty. Robert Herjavec was even more furious.
The tension spiked as the Sharks grilled the entrepreneurs, exposing flaws faster than they could defend themselves.
MinusCal’s Shark Tank pitch crashed – Mark Cuban, Robert Herjavec, and Daniel Lubetzky ripped into it
Some Shark Tank pitches go down in flames, but MinusCal might be one of the worst crashes in the show’s history. When the company stepped onto the stage claiming to have a fat-blocking protein bar, Mark Cuban was furious.
MinusCal’s founders pitched their protein bars and supplements, claiming they contained a special ingredient that blocked the absorption of dietary fat. Right away, the Sharks smelled trouble.
Robert Herjavec and Daniel Lubetzky pressed for scientific proof, but the answers didn’t hold up. Cuban, never one to hold back, called it a complete scam and slammed the product for misleading customers.
The founders tried to defend their science, referencing a study about chitosan, a fiber derived from shellfish, which they claimed reduced fat absorption. But the Sharks weren’t buying it. Lubetzky, founder of KIND Snacks, doubled down on the importance of real food over gimmicky diet tricks. Herjavec was visibly frustrated, as he said,
I’m so frustrated. I have no idea. I really don’t know what your business is. I don’t know what your strategy is. I really don’t know anything.
Mark, sometimes your level of arrogance really pisses me off, and I mark it out. And I only say that—you don’t give people a chance. I wish I knew what their business was if you would let people talk.
By the end of the pitch, the room was ice-cold. Not a single Shark made an offer. Cuban had the last word, saying MinusCal was one of the worst products to ever appear on the show.
Shortly after, the company disappeared from the market. No surprise there – when the Sharks call you a scam, it’s game over.
This Shark Tank disaster serves as a reminder: flashy health claims won’t cut it without real proof. And if you’re pitching Mark Cuban? You better come correct.
Mark Cuban drops meme coin plans after crypto scandal
Mark Cuban scrapped his meme coin plans after the Libra token scandal shook the crypto world. His idea? A token that could gamble its way into reducing U.S. debt. But after Argentina’s President Javier Milei faced fraud charges over his meme coin promotion, Cuban backed off.
Libra was meant to support small businesses. Instead, it crashed after its creators pulled the rug, leaving Milei scrambling to explain. Dubbed ‘Cryptogate,’ the fiasco sparked impeachment calls. Cuban called the meme coin space a game of musical chairs and demanded transparency.
Before this, he had some faith in meme tokens. But Trump’s TRUMP token changed that. Cuban dismissed it as self-serving bullshit, and the Libra fallout sealed the deal. His exit from the meme coin hype highlights the market’s chaos — something that needs fixing before it’s taken seriously.
