You know that feeling when you're staring at a plate of leftovers and thinking, "There has to be a better way than this flimsy plastic wrap"? Michael Tseng felt that deep in his soul. It led him to create the Plate Topper, a suction-seal lid designed to make Tupperware feel obsolete. It looked like a slam dunk. In fact, it's widely remembered as one of the most chaotic, legendary, and ultimately frustrating pitches in the history of Shark Tank.
Most people watch the show for the "happily ever after." They want to see the underdog get the check and become a billionaire. But the Plate Topper story is a masterclass in how a great product can get absolutely buried by the complexities of a deal. It wasn't just about a piece of plastic; it was about a founder who couldn't get out of his own way.
The Pitch That Broke the Tank
Michael Tseng walked into Season 4 with a product that worked. Honestly, it worked well. The Plate Topper used a medical-grade silicone gasket to create an airtight seal on almost any smooth surface. You just press it down on a plate, and suddenly your dinner is vacuum-sealed. No more searching for matching lids. No more wasting rolls of Saran Wrap.
The Sharks were biting. Fast.
Lori Greiner, the "Queen of QVC," saw the immediate retail potential. Daymond John and Kevin O'Leary were interested too. But what started as a feeding frenzy turned into a marathon of second-guessing. Tseng had already done significant sales—around $1 million—which is usually a green flag for the Sharks. However, as the negotiations stretched on for over two hours (edited down to ten minutes for TV), the tension became thick enough to cut with a steak knife.
Tseng’s biggest mistake? He started "Shark shopping." He had a deal from Lori on the table—$90,000 for 8%—but he kept looking at the other Sharks, trying to play them against each other. It was painful to watch. You could see Lori’s patience evaporating in real-time. Mark Cuban, who eventually bowed out, famously called the process "grinding," and not in a good way.
Why the Plate Topper Deal Actually Collapsed
If you follow the show, you know that a "handshake deal" on air isn't a legally binding contract. It’s a gentleman’s agreement to start due diligence. For the Plate Topper, the deal made on television was $90,000 for 5% equity with Lori Greiner.

It never closed.
Why? Because the reality of the business didn't match the momentum of the pitch. After the cameras stopped rolling, the relationship between Tseng and Greiner soured. Reports surfaced that Tseng changed the terms, or at least tried to. There was friction regarding how much control Lori would have over the brand. In the world of venture capital, if the founder is seen as "difficult" or "uncoachable," the money walks.
Lori eventually took to Twitter (now X) to clarify that she was no longer involved with the company. This happens more often than viewers realize. Roughly 30% to 50% of Shark Tank deals fall through during the due diligence phase. Sometimes the numbers don't check out, but often, it's just a personality clash.
The Post-Shark Tank Surge and the Pre-Order Nightmare
Even without Lori, the "Shark Tank Effect" is real. When that episode aired, the website was flooded. People wanted the Plate Topper. They ordered it in droves.
But the company wasn't ready.
Supply chain issues are the silent killer of small businesses. Tseng struggled to fulfill the massive influx of orders. When you have thousands of people who have already paid for a product and you can't ship it, the "customer service" emails turn into "customer anger" emails very quickly. This is where the lack of a Shark's infrastructure really hurt. If Lori had been on board, her manufacturing connections likely would have smoothed out the logistics. Instead, Tseng was flying solo.

Is the Plate Topper Still for Sale?
This is the question everyone asks. If you go looking for the original Plate Topper today, you might find some dusty stock on the back shelves of a random discount store, but the brand as we knew it has largely vanished from the mainstream.
There was a period where the product was available in Walmart and on Amazon. It had decent reviews, too. People liked the fact that it was BPA-free and dishwasher safe. But the market is ruthless. Once the initial hype of the TV appearance faded, the company had to compete on price and shelf space. Without the constant marketing engine of a major partner, it’s hard to stay relevant in the crowded "As Seen On TV" kitchen gadget aisle.
Today, if you search for the product, you’ll mostly find generic knock-offs. The patent-protected design was supposed to prevent this, but in the world of global manufacturing, staying ahead of copycats is an expensive, uphill battle.
Lessons for Entrepreneurs from the Plate Topper Saga
If you're an inventor or a small business owner, the Plate Topper story is actually more valuable than the success stories like Scrub Daddy or Bombas. It teaches the "what not to do" phase of business growth.
- Don't over-negotiate a good thing. Tseng had the perfect partner in Lori. She knew the kitchen space better than anyone. By trying to squeeze out an extra 2% or 3% of equity, he lost the expertise that would have scaled the company to $100 million.
- Infrastructure matters more than the invention. A great product is only 10% of the battle. The other 90% is shipping, logistics, and customer support. If you can’t get the product into the customer’s hands, the product doesn't exist.
- Transparency is key. During the pitch, the Sharks felt like they weren't getting the full story. In any business deal, if the other side senses you're hiding something or being evasive, they will pull the plug. Trust is the currency of the Tank.
The Current State of the Kitchen Gadget Market
The Plate Topper existed in a specific window of time. Since then, the market has shifted toward reusable silicone stretch lids and beeswax wraps. The "suction lid" concept hasn't died, but it has evolved. Companies like Gir or even IKEA have released their own versions of suction-seal covers.
What's fascinating is that Michael Tseng's original vision—reducing plastic waste—is more relevant now than it was in 2012. We are more conscious of single-use plastics than ever. Had the Plate Topper had the right management, it could have been the "Hydro Flask" of leftovers.

Instead, it remains a cautionary tale of what happens when a founder prioritizes "winning" the deal over "building" the business.
Moving Forward: What You Should Do Instead
If you're looking for a way to store food without plastic wrap, don't spend hours hunting for an original Plate Topper on eBay. The technology has moved on. Look for "platinum-grade silicone" lids that can withstand high heat. They perform the same function—creating a vacuum seal on your bowls—but they are often more durable and easier to store than the rigid plastic of the original Shark Tank product.
For those interested in the business side, go back and watch the Season 4 episode. It’s a masterclass in body language and the psychology of negotiation. Watch how the Sharks' expressions change from excitement to annoyance. It’s the best free business lesson you’ll ever get.
The Plate Topper might not be in every kitchen in America, but its impact on the Shark Tank legacy is permanent. It proved that a great product isn't enough to guarantee a "Happily Ever After." You need the right mindset to go with it.
Next Steps for Your Kitchen and Business:
- Audit your storage: If you're still using PVC-based plastic wraps, consider switching to silicone suction lids. They are safer for microwave use and significantly better for the environment.
- Study the pitch: Look up Michael Tseng's LinkedIn or recent interviews if you want to see how he's pivoted. He hasn't stopped inventing; he's just moved on to different projects.
- Check the reviews: Before buying any "As Seen On TV" product, always check for recent feedback regarding suction longevity, as silicone can degrade if washed with harsh detergents over several years.
