It could be so frustrating to lose your valuables in the gap between your car seats. You were just minding your business, driving, and then something dropped from your hand and disappeared into the “black hole,” never to return!
In Shark Tank Season 4 Episode 20, Drop Stop inventors Marc Newburger and Jeffrey Simon pitched the Sharks on their solution for keeping things out of the “Carmuda Triangle,” that little gap between a car seat and the center console.
Would the Sharks believe Drop Stop could solve a problem every driver faced and invest in the business?

Marc was inspired to invent the Drop Stop when he nearly wrecked his car after reaching for his cell phone, which had fallen into that gap as he was driving. He nearly killed a pedestrian and came within inches of smashing his car into a metal pole.
After that nearly fatal experience, Marc and his friend Jeffrey started brainstorming. They tried a bunch of different solutions to plug that gap, but they didn’t come up with anything until Marc had an epiphany.
He stuffed an automotive sponge into an old sock, cut a few slits in it (for the seatbelt receptacle), and tested it in his car; the Drop Stop was born. After a few years of developing the prototype, Team Drop Stop shot an infomercial and decided to swim with the Sharks.
Drop Stop Shark Tank Pitch
Marc Newburger and Jeffrey Simon entered the Tank with a compelling pitch. The entrepreneurs vividly explained the struggle of losing items to the dark holes of car seats. They had car seats arranged on the stage, where they demonstrated a real-life scenario.
They asked the Sharks, “Who had a two-year-old French fry stuck between the seats?” and “Who hadn’t struggled to get on their knees to retrieve something that just fell in between the seats?” Then, the entrepreneurs presented their product, designed to save the day.
After telling the tale of the inspiration behind their product, Mark Cuban asked them how much money their business could make. The entrepreneurs revealed they had sold over 250,000 units.
Kevin O’Leary was eager to know the value of those sales in dollars and questioned them further. In response, the founders proudly shared that their total sales amounted to $1.3 million.
Lori Greiner was interested in knowing how they sold the product. Marc and Jeffrey explained that they sold it through their website and catalogs. Apart from that, they had appeared on QVC 42 times.
Mark Cuban then asked about the selling price and manufacturing cost. The founders explained that it cost $4 to manufacture a set of two, and they sold it for $19.99.
What Makes Drop Stop Unique?
Did Drop Stop Get a Deal on Shark Tank?
Kevin O’Leary was the first Shark to make an offer, but before that, Robert Herjavec wasn’t a true believer in Drop Stop, so he was out.
Daymond John liked the sales numbers, but he followed Robert out.
Mark Cuban liked the product and thanked Marc and Jeffrey for the sample, but he didn’t think he could add value, so he was out.
Kevin O’Leary offered $300,000 in exchange for a $2 royalty on every unit sold.
Lori Greiner emphasized her retail expertise and painted a picture of the company’s future success, encouraging the founders to partner with her. Kevin O’Leary countered with $300,000 for a $1 per-unit royalty.
Marc Newburger and Jeffrey Simon liked Lori Greiner’s vision and accepted her offer of $300,000 for 20% equity.

Thank you for inventing the Drop Stop. My father, just this week, dropped his keys in between the console and seat. He just purchased a car with a push button start and is trying to figure out what to do with the keys. We were on our knees in the car for a few minutes trying to find the keys. I am interested in purchasing this product for them.
