4. First Defense Nasal Screens
Manufacturing nasal air filters, the company was already doing good business, having secured an $8 million overseas contract. The sharks realized a good opportunity when they saw it and an outright bid of $4 million was made from Robert Herjavec. Founder Joseph Moore instead opted for a $750,000 loan in exchange of 30% of the company, which he then later rejected as well. Now, the product is sold in over 30 countries and is protected by multiple patents.
