For individuals who lead busy lives and are always on the move, Coffee Joulies offers a convenient way to enjoy their favorite hot beverage without the risk of burning their tongues. The portability of the beans makes them an ideal companion for commuters, travelers, and anyone who needs their coffee fix outside the home [3].

2) Frequent Travelers

Traveling often means encountering a range of coffee temperatures, from overly hot to lukewarm. Coffee Joulies can be a travel-friendly solution to ensure a consistently enjoyable cup, regardless of the coffee available at various destinations.

3) Office Workers

Individuals in bustling offices, coffee shops, or other noisy settings may find this a minor inconvenience compared to the benefits of having consistently tempered coffee.

8) Gift Recipients

Given their unique and innovative nature, Coffee Joulies make for an excellent gift for coffee lovers. The combination of functionality, durability, and customization options can make them a thoughtful and practical present for birthdays, holidays, or special occasions.

About Founders Of Coffee Joulies

The masterminds behind the innovative Coffee Joulies are none other than Dave Petrillo and Dave Jackson, both hailing from the mechanical engineering realm in New Jersey [4]. These enterprising individuals conceptualized small, stainless-steel capsules that housed a brilliant material engineered to swiftly cool a piping hot beverage to a palatable temperature. What set the Coffee Joulies apart was their subsequent ability to sustain the drink at that ideal temperature for an extended duration. 

In their quest to bring this groundbreaking concept to life, Petrillo and Jackson initiated a Kickstarter campaign in March 2011 to secure the necessary initial funding. Their ambitious goal was set at $ 9,500, and to their delight, this target was not only met but surpassed within a mere three days. The month-long campaign proved to be a resounding success, as the Coffee Joulies project garnered substantial support from the Kickstarter community. A staggering 4,800 backers rallied behind the idea, pledging over $ 300,000 to propel Petrillo and Jackson toward the realization of their visionary product [5].

About Founders Of Coffee Joulies

The early triumph of their crowdfunding campaign provided not only financial backing but also a vote of confidence from a substantial community of enthusiasts. Armed with this substantial support, Petrillo and Jackson navigated the manufacturing process with ease, transforming their conceptualized idea into a tangible and finished product that would revolutionize the way people enjoyed their hot beverages.

The Coffee Joulies, born out of ingenuity and propelled by community support, became a testament to the power of innovative thinking and collaborative funding in bringing revolutionary ideas to fruition.

The Pitch Of Coffee Joulies At Shark Tank

In the early part of 2013, mechanical engineers hailing from New Jersey, Dave Petrillo and Dave Jackson, unveiled their brainchild, Coffee Joulies, on the renowned TV show “Shark Tank.” Their pitch sought a $ 150,000 investment in exchange for a modest 5% stake in their business [6].

Dave Jackson commenced the pitch with confidence, shedding light on the inconvenience of coffee being typically served at a scorching 179 degrees Fahrenheit. This meant that drinkers had to endure a wait until the beverage reached a drinkable temperature, consuming it hastily before it cooled down.

The dynamic duo elucidated the functionality of Coffee Joulies—small stainless-steel capsules housing an ingenious material. When immersed in hot coffee, these capsules absorbed excess heat, rapidly bringing the drink to an optimal temperature.

Subsequently, they released the stored heat back into the beverage, maintaining it at the perfect drinking range for an extended period. Moreover, when used in a vacuum-insulated travel mug, the drink reached the ideal temperature in a mere five minutes and stayed that way for over five hours.

During a unique demonstration, the sharks were presented with coffee poured three hours earlier, still visibly steaming. This visual spectacle captivated the sharks, with Robert Herjavec particularly impressed by the longevity of the coffee’s heat.

As the pitch unfolded, questions arose. Lori Greiner noted that a Thermos could also keep coffee hot, prompting Petrillo to highlight that a Thermos could keep the coffee too hot for an extended period, unlike Joulies, which cooled it quickly.

Mark Cuban inquired about the monitoring of the drink’s heat, leading Jackson to explain the absorption process until the drink reached a comfortable 140 degrees. At this point, the Joulies would release the stored heat back into the drink.

The sharks delved further, asking about the material composition. Petrillo revealed the high-grade stainless-steel casing and proprietary phase-change material for heat absorption, emphasizing its safety and edibility. However, the specifics of the material remained undisclosed.

The Pitch Of Coffee Joulies At Shark Tank

Despite some reservations and Daymond John initially opting out, a compelling financial overview unfolded. The partners shared that each Joulie cost $ 3.65 to manufacture and test, retailing at $ 50 for a set of five. Previous-year sales amounted to $ 575,000, albeit with a profit of $ 50,000, considering hefty expenses in tooling, patents, and legal fees.

When Kevin O’Leary sought a 33% interest, he proposed an alternative—a $ 150,000 investment in exchange for a royalty of $ 6 per unit until recouping the investment, then dropping to $ 1 in perpetuity [7]. Lori Greiner expressed interest, envisioning QVC’s support for the product. Robert Herjavec also wanted in, citing his ability to facilitate Joulies’ entry into retailers.

A twist ensued when Daymond John, initially disinterested, reconsidered, eager to join the collective offer made by Kevin, Lori, and Robert. Mark Cuban, preferring a solo investment, offered $ 250,000 for a 12% stake without additional royalties. His vision included a slower build-up for the product and business.

The partners requested a break to consult, prompting Robert to caution Kevin about the high royalty figure for wholesale sales. Concerns were raised, and Kevin interrupted the consultation to propose an improved deal: royalties at $ 6 per retail unit and $ 3 per wholesale unit until recouping the investment, then dropping to $ 1 per unit in perpetuity.

Upon their return, the partners weighed the options and opted for the revised offer from Kevin, Lori, Robert, and Daymond. Despite Mark Cuban’s graceful acceptance of rejection, the air buzzed with excitement as the other sharks welcomed the new partnership, sealing the deal with smiles and handshakes.

Coffee Joulies After The Shark Tank

While a plethora of culinary innovations introduced on “Shark Tank” tend to fizzle out post-show, Coffee Joulies stands out as a success story. Securing a deal with sharks Kevin O’Leary, Lori Greiner, Robert Herjavec, and Daymond John initially brought immense satisfaction to entrepreneurs Dave Petrillo and Dave Jackson. However, it appears that the ink on the deal may never have dried [8].

In a conversation with the Observer-Dispatch, Petrillo expressed gratitude for the “Shark Tank” exposure, citing unexpected boosts across all categories. Despite their initial pitch focus on the retail and wholesale avenues, the dynamic duo seemingly pivoted away, prioritizing direct-to-consumer sales through the Coffee Joulies website, with retail and wholesale operations taking a backseat.

Operating sans a Shark-backed support system, Coffee Joulies achieved impressive sell-out scenarios, necessitating multiple breaks to replenish stock. The irregular availability of Coffee Joulies could pose a substantial challenge. The burning question then arises: where does the company stand today?

Fast forward to August 2023, and Coffee Joulies boasts a valuation of around $ 5 million. Not content to rest on its laurels, the company expanded its product line to include glass mugs and Beer Joulies, designed to maintain cold beverage temperatures [9].

Yet, the winds of change are blowing once more, as evidenced by the deactivation of the company’s website. In February 2023, Coffee Joulies reappeared on Facebook after a six-year hiatus, announcing limited-time availability through Thread & Leather.

Coffee Joulies After The Shark Tank

However, only the original Coffee Joulies are on offer, and they come bundled. For $ 119, consumers can snag five Coffee Joulies and an insulated travel mug, while $ 139 fetches six Coffee Joulies and two insulated travel mugs.

Opting for a different purchasing route, Coffee Joulies (available separately) can be procured on Amazon, priced at $ 39.99 for a five-pack. Alas, the product sports a three-star rating, with disgruntled customers citing its effectiveness solely in insulated tumblers and expressing dissatisfaction with the number of beans required to maintain coffee warmth.

As we peer into the horizon, it regrettably seems that Coffee Joulies might be concluding its narrative. The company’s website lies dormant, and its social media profiles echo with a conspicuous absence of recent activity.

Dave Petrillo retains his title as company president on LinkedIn, but his professional journey has taken a detour. He spent the past five years at Peloton as an engineer and hardware lead. Meanwhile, Dave Jackson, identified as a Coffee Joulies co-founder on Facebook, embarked on a new venture, SpeedBoard, in 2019. 

Unfortunately, SpeedBoard’s trajectory mirrors that of Coffee Joulies, with a mere $ 44k raised on Kickstarter and no Facebook updates since 2020 [10]. The social media landscape echoes with demands for answers, with one user accusing the company of executing a “grab and go” with people’s hard-earned money.

The Net Worth Of Coffee Joulies

As of 2023, Coffee Joulies has an estimated net worth of $ 5 million [11]. This marks a significant increase from when founders Dave Jackson and Dave Petrillo first pitched their product on Shark Tank in 2013, where the company was valued at $ 3 million.

The company’s revenue is also impressive. It’s reported that the company is pulling in less than $ 5 million annually. The product itself costs $ 3.60 to manufacture each unit, and they sell for $ 50 per package of five [12].

Despite this success, there have been conflicting reports about the status of the company. One source claims that Coffee Joulies is out of business, although this seems to contradict the majority of the information available.
