Mark really does seem like a stand up guy.
Shark Tank sounds kinda 'fluffy' and I never paid it much attention for the first few seasons - but then I heard about a company that pitched and I was intrigued so I was searching through the episodes of one of the earlier seasons and I realized how awesome the show is.
It is amazing to watch and see how quick the Sharks can sniff out vagaries of a deal - e.g. if an entrepreneur raised money before at some crazy price, or the cap table looks very weird, or the company was loaded up with debt. They always seem to get to that pretty quickly.
I wonder if that is because they (the show) do due diligence on each company before they reach the sharks and the sharks have notes about what to ask for.
Either way, I am always surprised by the quality of the pitches shown. Some are lame, but some are surprisingly good with solid business and likely solid growth prospects.
As a general rule, their instincts tend to be pretty spot-on - it seems.
