Coffee Joulies

Coffee Joulies were small metal capsules meant to be dropped into a hot drink. A material inside them was designed to absorb heat when coffee was too hot and release it slowly as the drink cooled, keeping it in a comfortable range for longer. The product was invented by Dave Petrillo and Dave Jackson, who started it in Pennington, New Jersey, and later manufactured it in Sherrill, New York. The two founders pitched in Season 4, Episode 13, asking for $150,000 in exchange for 5% of the company. Instead of buying equity, a group of four sharks (O'Leary, Greiner, Herjavec and John) offered a joint royalty deal, and the founders accepted on camera. The product had already drawn attention through crowdfunding before the show, and reviews were mixed on how well it worked in practice. The royalty arrangement most likely never closed. Secondary sources say it never went through, and a local newspaper reported that negotiations were still ongoing weeks after the episode aired. Neither the founders nor the sharks have publicly settled the question, as far as we can find. The company's online stores now show a notice that they are unavailable, and we have not yet checked state business records. So this page uses an unknown status, not closed, and we found no official place to buy the product today. The manufacturing history and the deal reporting are covered in the update below.
