Following its successful stint on Shark Tank, Plate Topper has emerged as a highly coveted item in kitchenware boutiques, thanks to its uncomplicated yet efficient construction.

About the Founders Of Plate Topper

Michael Tseng, the mastermind behind Plate Topper, is an exceptional individual with a remarkable academic background. His brilliance is undeniable, having earned degrees in both electrical and biochemical engineering from Princeton University, in addition to a medical degree from the University of California, San Francisco [6].

However, despite his promising career in medicine, Michael made the unconventional choice to forgo a medical residency and venture into the world of entrepreneurship. Today, he proudly serves as the CEO of Prestagon LLC, the company behind Plate Topper.

The genesis of Plate Topper can be traced back to Michael’s innovative mind. While he was away from his university and residing in his hometown, a groundbreaking idea began to take shape. It all started with the concept of a suction plate, which he later ingeniously combined with the idea of a microwave-safe plate cover.

Michael’s journey into the world of kitchenware innovation began seven years ago, but he officially entered the business just a year ago. His inspiration came from observing the challenges people faced with traditional food storage containers. It became apparent that standard lids were often misplaced, and plastic containers suffered from frequent wear and tear. The result was messy microwave spills, leading to frustrating cleanup tasks.

About the Founders Of Plate Topper

In response to these common issues, Michael Tseng conceived Plate Topper as a solution to create a cleaner and more convenient kitchen environment. The Plate Topper not only prevents spills in the microwave but also maintains food freshness. Its versatility extends to microwave use and dishwasher-friendly cleaning, making it a practical and durable addition to any kitchen.

To safeguard his groundbreaking invention, Michael secured a patent, ensuring that Plate Topper remains his intellectual property. Before even appearing on Shark Tank, Plate Topper had already made its mark on platforms like QVC and Walmart, showcasing its exceptional product quality and market presence [7].

The Pitch Of Plate Topper At Shark Tank

Michael Tseng confidently entered the Shark Tank, warmly greeting the panel of Sharks. He introduced himself and initiated his pitch, seeking a $ 90,000 investment in exchange for a 5% equity stake in his company, Plate Topper [8].

Michael immediately highlighted the flaws in conventional food storage methods, such as plastic wrap and Tupperware, emphasizing the common problem of plastic lids disappearing. He went on to deride plastic wrap as a messy inconvenience, using a visual aid of scattered plastic wrap and a messy microwave as evidence.

To demonstrate Plate Topper’s effectiveness, Michael placed a small plastic container with a handle on a plate, showcasing how the seal was strong enough to lift the entire plate. He emphasized Plate Topper’s microwave safety and ease of removal using the pull tab.

Continuing his presentation, Michael stressed the simplicity of cleaning the Plate Topper, as it was dishwasher safe. He touted its benefits, including preventing microwave spills and keeping food warm after heating. He also highlighted its easy storage as the Plate Toppers nested neatly in cupboards.

In a somewhat infomercial-like tone, Michael teased the Sharks, saying, “But wait, there’s more”, which elicited laughter from the panel. He unveiled three new Plate Topper variations: the Plate Topper Mini, a slightly larger size, and the Cake Topper, which revealed a cake beneath it. The Sharks reacted with enthusiasm to these innovations.

Michael mentioned that he already had purchase orders from two major retailers and emphasized the need for the Sharks’ assistance in fulfilling these orders.

After concluding his presentation, Michael handed out samples of Plate Toppers to the Sharks, who eagerly examined them. Lori inquired about the retailers where Plate Topper was available, and Michael mentioned that the product had been featured on QVC and Walmart’s website. However, Lori pressed further, asking about physical retailers. 

Robert praised the product’s elegance compared to plastic wrap and its disposable counterparts, expressing his disdain for plastic wrap. Michael shared that he came up with the concept during a college break and combined the idea of a suction plate with a microwave cover.

The Pitch Of Plate Topper At Shark Tank

Lori inquired about Michael’s background in engineering or product development, to which he revealed his studies in electrical engineering at Princeton University and later in biochemical engineering and medical school. Daymond seemed impressed by Michael’s educational background.

When Kevin playfully referred to Michael as “Dr. Plate Topper”, Michael clarified that while he was a physician on paper, he was not currently practicing medicine. He mentioned that he took a year off from his medical practice to fully dedicate himself to entrepreneurship. Michael also pointed out that he held a Utility Patent for a Plate Topper.

Kevin asked about the best-case sales scenario for the next 12 months. Michael disclosed that he had received purchase orders totaling over a million dollars in just four months, with $ 500,000 in profit. Kevin praised the product but offered a deal where he would take a 5% royalty instead of equity, claiming that he was more interested in Michael himself and his involvement in marketing the product on QVC.

Daymond commended Michael’s intelligence but accused him of being greedy and stated his desire to be Michael’s partner. However, Daymond called Michael out for offering the Sharks a low equity percentage of $ 90,000 in exchange for 5% of the company. Daymond walked away from the deal, and Michael attempted to engage him but was unsuccessful.

Lori, appearing frustrated, revisited her offer, proposing $ 900,000 for a 30% equity stake and outlining her plans to create a separate infomercial and leverage her retail connections. Daymond countered with a $ 1 million offer for 25% equity but emphasized that he didn’t have Lori’s extensive connections.

Kevin contemplated making an offer but ultimately decided against it, stating that all roads led to him for a royalty deal, and he wouldn’t accept equity.

Lori, feeling exasperated, suggested reverting to her original offer of $ 90,000 for 5% equity [9]. Kevin urged Michael to make a decision, and Michael, under pressure, accepted Lori’s offer. Afterward, Robert expressed his shock at Lori’s decision to invest, while Daymond shared his frustration with Michael’s negotiation tactics. Lori defended her choice, emphasizing her belief in the product.

As Michael left the Shark Tank, he seemed relieved to have secured a deal with Lori, and the Sharks continued their discussions about the pitch.

Plate Topper After The Shark Tank

Despite the negotiations, it seemed that Michael Tseng’s Plate Topper had some potential by the end of the Shark Tank episode. However, shortly after the show aired, Lisa Greiner took to her Twitter account to announce that the deal had fallen through: “Regrettably, I didn’t quite appreciate his tactics either; the struggle didn’t end in the tank. I’m out”. 

Although the tweet has since been removed from Greiner’s Twitter feed, it’s still visible on the Shark Tank Blog, which managed to secure an interview with Tseng around the same time.

According to the creator of Plate Topper, the post-show developments were quite different from what viewers saw on TV. He stated, “As I mentioned before, it’s impossible to separate the negotiations that happen during and after the show before it airs, but that wasn’t fair. Lori insisted on having exclusive decision-making authority over the company for a full year before finalizing the deal we made on TV,” he shared.

Plate Topper At Shark Tank

“I consulted with my lawyers… and no venture capitalist would try to control a company before investing. I attempted to negotiate a shorter period with her, but she wouldn’t agree. I believe it’s patronizing to suggest that my ‘antics continued after the show.’ There was no way I would agree to that.”

It appears that Greiner’s involvement was just not meant to be. While Plate Topper may not be classified as one of the food-related disappointments on “Shark Tank”, the situation was undeniably a setback.

While the fallout between Michael Tseng and Lori Greiner post-show might imply that Plate Topper is no longer in operation, that’s not entirely accurate. Although Tseng’s product is no longer listed on Walmart’s or QVC’s websites, it is still available for purchase on his company’s own website. The company has now rebranded as Prestagon, Inc. and offers a range of products beyond the Plate Topper, including fitness equipment, a roll-up tool bag, and a set of pet stairs.

Furthermore, the airtight plate cover designed to simplify food storage has undergone a rebranding as well. Instead of being known as Plate Topper, the product is now called MyTopper.

In addition to the original item, customers can now purchase the IceTopper, a stackable ice cube tray available in various sizes and bundles. Tseng managed to keep his company afloat despite losing Greiner’s support.

Michael Tseng’s future plans remain somewhat mysterious, aside from expanding Prestagon, Inc.’s product portfolio. According to Tseng’s LinkedIn profile, he still holds several patents and trademarks and is actively involved in developing Prestagon, Inc. [10] Moreover, the company maintains an active presence on social media, thanks to Prestagon Pets’ Facebook page.

In any case, Tseng’s legacy endures, and he used his 2012 interview with the Shark Tank Blog to provide advice for other entrepreneurs.
