NerdWax Shark Tank pitch
Don and Lydia Hejny created Nerdwax out of necessity. Don, a touring audio engineer, found himself constantly frustrated by his glasses slipping off during shows. The couple decided to solve this problem by developing a wax that creates friction between glasses and skin. They started small, making the wax in their kitchen. However, early challenges included manufacturing disasters and limited resources. Still, their determination and vision helped them bring Nerdwax to life.
Don and Lydia entered the tank with their children, making their pitch a family affair. They explained how Nerdwax works by applying a thin layer of wax to the nose pads or bridge of glasses, wearers can enjoy hours of slip-free comfort. The product costs $0.35 to make and sells for $10 per tube.
In their first year, they made $136,000 in sales. The couple wanted the sharks’ help to scale production and reach more customers. They asked for $80,000 for 20% equity, hoping a shark’s expertise would take their business to the next level.
Mark Cuban: “How do you prevent big competitors from copying your idea?” Don replied that their focus was on building a strong brand and loyal customer base.
Kevin O’Leary: “What’s stopping this from being a one-time purchase?” Don explained that each tube lasts 6 to 8 months, so repeat customers appreciate the convenience and effectiveness of Nerdwax.
Lori Greiner: “How scalable is this business?” Don admitted they were still learning but hoped the sharks could guide them.
Kevin O’Leary offered $80,000 for 10% of sales until he recouped $240,000, plus 3% equity.
Troy Carter offered $80,000 as a loan with a $120,000 payback for 10% equity.
Lori Greiner and Mark Cuban did not make offers, citing scalability concerns.
After some advice from Mark to avoid scaling too quickly, Don and Lydia decided not to accept any deals.
What Went Wrong With NerdWax On Shark Tank?
The main issue was the sharks’ doubts about the business’s scalability and competition. Lori and Mark felt Nerdwax wasn’t a large enough opportunity for investment, while Kevin’s offer was too sharky for the founders. Additionally, the couple’s decision to stick to their vision may have made the sharks hesitate.
Product Availability
NerdWax is still available and thriving. Customers can buy the product on the company’s website and other online platforms. Each tube is priced at $10, and multi-packs are available for added value. The wax is easy to use, effective, and loved by many loyal customers.
Conclusion
Nerdwax entered the tank as a small family business with a big idea. Although Don and Lydia didn’t secure a deal, their time on Shark Tank gave them invaluable exposure and advice. Today, Nerdwax is a thriving brand earning millions in revenue, proving that rejection isn’t the end of the road.
Their journey inspires entrepreneurs to stay committed to their vision, no matter the challenges. Nerdwax is a testament to the power of persistence and belief in your product. We look forward to seeing how Don and Lydia continue to grow their business in the years to come.
