Marc Newburger and Jeffrey Simon created Drop Stop in 2009 to solve a common problem, items falling into the gap between car seats. They pitched their product on Shark Tank in 2013, securing a $300,000 deal with Lori Greiner for 20% equity.
The investment and Lori’s guidance helped Drop Stop reach over $5 million in annual revenue by 2025. Today, the product is sold in major stores like Walmart and Amazon, and it remains a favorite for drivers seeking safer, clutter-free rides.
Drop Stop continues to grow, proving that simple ideas can lead to big success.
