Setting the record straight as to why this happens, multi-millionaire investor, Peter told the BBC last year that a lot of the time, deal destroying issues that weren't immediately present start to emerge after you see the dragons shake hands with their new business partners. "You go through it with a toothpick… that's where these things fall down," he said.
He explained that there are many reasons as to why successful deals fall through, including entrepreneurs inflating their sales figures or providing other wrong information during their pitch.

"I'm not saying the entrepreneur is trying to tell us things that aren't true, but through excitement or being unprepared, their numbers maybe got a bit mixed up in their head," Peter said.
He continued: "That's 90% of the reasons why things in the Den fall through, but there's another part of it. Sometimes people come into the Den, get a deal, and think, 'We're on TV, that'll be great for my product,' and they drag out the due diligence.

"They're thinking that if they can get their product on air they'll get fame, and maybe won't even need a Dragon, which is disappointing, but does happen."
While the BBC do some due diligence before they allow contestants to pitch in front of the dragons, the dragons themselves also check over business plans and have legal teams draw up new contracts before any money is handed over.

It's what proved fatal for several companies, including Vitiliglow, a make-up product for sufferers of skin condition vitiligo pitched by Polly Gotschi and Rugged Interactive, a fitness games platform pitched by Simon Heap, as well as many more. The entrepreneurs walked away with thousands of pounds worth of investments from the dragons which never transpired due to disagreements behind the scenes.
A BBC spokesman explained: "All the successful entrepreneurs enter into the normal period of rigorous due diligence with the dragons once a deal has been struck and, as is often the case in the real world, deals can fall through."
