14. Chord Buddy
Alabama father Travis Perry came up with the Chord Buddy idea after seeing his daughter, an inspiring guitarist, about to quit practicing the guitar.
He walked into the Shark Tank seeking $125,000 for 10% equity. The sharks were impressed to learn that Perry had already scored $1 million in sales and that his product was already being sold by Sounds, an important retailer in the industry. In the end, he made a deal with Robert Herjavec, and managed to make around $1.5 million in just one year.
