James Martin is president and founder of Copa Di Vino, the second largest winery in Oregon. He appeared on "Shark Tank" twice, and walked away from a deal for his wine-by-the-glass product twice.
But like a lot of other people who have left the show without an investor, his appearance on the show changed things. This is known as the " 'Shark Tank' effect."
"The night of the airing of our episode we had over 300 investor phone calls come in," he told CNBC.com. "By the end of that week, we had over a thousand. We had about 10,000 hits to our website every minute. It was insane."
