Firefly Recovery Update | Shark Tank Season 16
While working with college and pro athletes, Anthony Kjenstad saw the same problem over and over—recovery tools like compression boots were too big, took too much time, and stopped athletes from moving around. So, he came up with Firefly Recovery, a small, easy-to-use device that helps muscles recover faster by improving blood flow. It lets athletes stay active while they recover. But did the sharks think it was worth the price? Let’s find out in our Firefly Recovery update and pitch recap.

Shark Tank Firefly Recovery Pitch
- Entrepreneurs: Anthony KJenstad and Lauren Campbell
- Business: Portable athlete recovery device
- Ask: $500,000 for 2.5% equity
- Result: $500,000 for 5% equity
- Sharks: Rashaun Williams and Lori Greiner
Anthony and Lauren introduced Firefly Recovery to the sharks, a company focused on muscle recovery.
They asked for a $500,000 investment and right away, they explained the problem.
Athletes care about recovery, but current tools are bulky and inconvenient. Compression boots, for example, are large and require users to stay still.
Firefly offers a better solution. Their product is small, portable, and easy to use. It stimulates the peroneal nerve, making the foot flutter.
They call this the “Firefly Flutter.” The movement boosts blood flow and reduces soreness. This helps users recover faster and feel better.
To show how it works, they invited Kerri Walsh Jennings, a five-time Olympian and three-time gold medalist to join them.
She shared her experience, telling the sharks that the product made her legs feel lighter and helped her stay fresh during training.
The entrepreneurs emphasized that the product is for recovery, and not for treatment of an injury.
Anthony explains to the sharks that the product can replace compression boots and works while users walk around, unlike traditional boots that require sitting still.
Daymond John asked if it only worked on the legs. Anthony said yes, but explained that 70% of blood is in the lower body. Stimulating circulation there helps the entire system. The product uses OnPulse technology to create a full-body effect.
Lori Greiner then asked about patents. Anthony said they have 47 utility patents across nine families.
Kevin O’Leary wanted to know why the business was worth $20 million.
Lauren explained they have $7.5 million in lifetime sales, with $4 million in the last 12 months. They are expecting to hit $5.5 million this year.
She added that they started with team sales but are now growing their direct-to-consumer side.
They raised $1 million in 2022 through an athlete-led round at a $10 million pre-money valuation.
The product costs $17.30 to make and sells for $48. One set lasts about a month with daily use.
Mark Cuban asked if repeat buying frustrated customers. Anthony said no. At $3 per treatment, customers felt it was worth it.
Still, Mark wasn’t convinced. He argued that most people wouldn’t pay $48 a month for recovery. Lori disagreed. She said people would pay to feel better.
Kevin liked the product but couldn’t accept the valuation, so he exited the negotiations.
Daymond found the deal structure too confusing and passed on investing.
Mark didn’t believe everyday people would keep paying that much for recovery. He’s out.
Lori and guest shark Rashaun Williams teamed up to offer $500,000 for 5% equity, plus a $1.50 royalty until repayment, and $0.50 in perpetuity.
Lauren pushed back on the royalty. She said the business needed to reinvest its earnings. They countered with 3.5% equity and no royalty.
Rashaun and Lori refused. They argued their royalty was worth the free marketing support.
Later, they offered a clean deal instead—$500,000 for 5% equity, no royalty. Lauren and Anthony took a moment to decide and ultimately accepted the new offer.
Now, let’s check in for a Firefly Recovery update.
