Marc Newburger and Jeffrey Simon faced the sharks in Season 4, Episode 20 in the episode that aired March 29, 2013, bringing their Los Angeles, CA business with them. Drop Stop, the automotive, pitched in the Automotive category, one of 17 automotive businesses to brave the Tank across all 17 seasons.
They came in asking $300,000 in exchange for 15% equity, putting a $2M valuation on the business.
Lori Greiner made the deal at $300,000 for 20% equity. That priced the company at $1.5M, a haircut from the $2M the founders walked in asking for, which is how negotiations in the Tank usually go.
Across Season 4, 52 of 103 pitches ended in a handshake. In the Automotive category overall, roughly 76% of pitches have landed a shark across the show's history.
The full story
Everything to know about Drop Stop
Drop Stop is a simple foam wedge that fills the gap between your car seat and the center console so phones, keys, coins, and fries stop disappearing into it. The product was invented by two childhood friends from Los Angeles, Marc Newburger and Jeffrey Simon, after Jeffrey nearly crashed reaching for a phone that had slid into that exact gap. They built a flexible barrier that slides over the seatbelt catch and moves with the seat.
Marc and Jeffrey came into the Tank asking 300,000 dollars for a 15 percent stake, with real sales already on the board. Their pitch leaned on the universal frustration of losing things in the seat gap, which every shark instantly recognized. Lori Greiner connected with the product as a clear retail item and an easy on-air demo. After some back and forth she invested, taking a larger equity share than the founders first wanted but bringing serious distribution muscle.
The product stood out because the problem is so common and the fix is so obvious once you see it. There was nothing to explain twice. Lori positioned it as a low-cost impulse buy, the founders went on The View and sold thousands more, and Drop Stop became one of the best selling automotive accessories online rather than fading away like many one-trick gadgets.
Where Drop Stop is now
After the episode, Drop Stop became a top selling car accessory on Amazon and rolled out into big retailers including Walmart and Bed Bath & Beyond. A Shark Tank update segment reported that the company had passed 24 million dollars in lifetime sales, and the founders have said it has sold millions of units across its run.
Drop Stop is still operating in 2026, with the original wedge plus newer versions and related car organizers. The founders have kept a close relationship with Lori Greiner years after the deal, and the company continues to sell through its own website, Amazon, and national retail. It remains one of the cleaner long-term success stories from the show.
Where to buy Drop Stop
Drop Stop is sold on Amazon and through the official Drop Stop site, usually as a pair so both seats are covered. You get two wedges that slide onto the seatbelt catch and flex with the seat, fitting most vehicles. It is inexpensive and solves a real everyday annoyance, which is why it has stayed a steady seller for over a decade. For anyone tired of fishing a phone out of the seat gap, it is an easy buy.
