ABC’S hit business-pitch reality show, some entrepreneurs walk away with life-changing deals. But more often than not, those on-air pacts don’t stick. FORBES fact-checked 237 of the 319 deals that closed on the show in its first seven seasons. Some 73% of the entrepreneurs didn’t get the agreement they made on TV, including 43% who didn’t get a deal at all. For 30%, the deal terms changed. Considering only the 160 solo deals offered by the six main sharks, Mark Cuban stuck to his on-air promises the most. Worth $3.3 billion, he’s vastly wealthier than the other sharks, none of whom appear to be even halfway to billionaire status (Robert Herjavec is likely the second richest). “The sharks are investing real money,” says ABC’S Marsha Smith. “In the real world there is a due diligence period after the initial agreement.” None of the sharks commented.
