Fiber Fix, the super-strong repair wrap that promised to be “stronger than duct tape,” made a splash on Shark Tank. But what happened after their appearance in the tank? How much did they actually make, and where are they now? The answer is impressive: Fiber Fix generated over $50 million in retail sales after landing a deal with Lori Greiner.

Their journey is a fascinating case study in leveraging a Shark Tank appearance into a thriving business. Let’s dive into the details of their success, the deal they secured, and where you can find Fiber Fix today.

The Shark Tank Deal That Changed Everything

Fiber Fix walked into the Shark Tank seeking $90,000 for 10% equity, placing a $900,000 valuation on their company. They ultimately secured a deal with Lori Greiner: $120,000 for 12% equity, which valued the company at $1 million.

But the road to getting that deal wasn’t easy. Kevin O’Leary and Robert Herjavec also presented offers, suggesting the Sharks saw real potential. Ultimately, the founders chose Lori Greiner, likely due to her expertise with QVC and her knack for turning products into retail sensations. Daymond John bowed out citing a conflict with his existing HSN contract, and Mark Cuban expressed concerns about long-term sustainability and valuation. Initially, Greiner offered $250,000 for 18%, which they countered before agreeing to the final terms.

$50 Million and Beyond: The Profit Surge After Shark Tank

The “Shark Tank effect” is very real, and Fiber Fix is a prime example. Airing on October 25, 2013, their episode triggered a massive surge in demand. Driven by increased visibility and the credibility boost from Lori Greiner’s endorsement, Fiber Fix exploded onto the retail market.

Hitting $50 million in retail sales after Shark Tank is a testament to the product’s appeal and the effectiveness of their post-show strategy. This growth speaks to a real consumer need for a reliable and robust repair solution, and Fiber Fix filled that gap perfectly.

From Shark Tank to Acquisition: The Next Chapter

Fast forward five years, and Fiber Fix reached another significant milestone: acquisition. In 2018, J-B Weld, a well-established adhesive manufacturer, acquired Fiber Fix. This acquisition allowed Fiber Fix to leverage J-B Weld’s existing distribution network and further expand its reach.

While the original Fiber Fix company shows a net worth of $0 in 2025, the brand lives on. It’s now sold as FiberWeld under the J-B Weld umbrella, continuing to provide consumers with its strong and versatile repair capabilities.
