Product Update
Is Firefly Still in Business? (2026 Update)
Is Firefly from Shark Tank still around in 2026? The deal it made, the sharks who invested, and where to buy Firefly today.
Firefly is the little band that straps below your knee and taps the peroneal nerve with electrical pulses, and it came into Shark Tank Season 16 with a resume most pitches would kill for: the device was already in use across professional and college sports. Anthony Kjenstad and Lauren Campbell asked the sharks to accept a 20 million dollar valuation. Kevin O'Leary flatly refused to. Lori Greiner and Rashaun Williams made a deal anyway, and in 2026 the company is running strong.
The Short Answer
Yes, Firefly is in business. The official store at fireflyrecovery.com is active, selling individual devices for about 49 dollars, starter packs in the 105 to 116 dollar range, plus straps and carrying cases. The old recoveryfirefly.com address now redirects there, so do not be thrown if a bookmark bounces you to the new domain.
The brand's calling card is its team roster. The site states that more than 1,300 professional and college teams use Firefly, and its testimonials include Tara Davis-Woodhall, the 2024 Paris Olympics long jump gold medalist. This is a recovery product with a foothold in serious sport, not a late-night gadget.
The Shark Tank Pitch
Kjenstad and Campbell appeared in Season 16, Episode 14, which aired in March 2025. Their device is a single-use wearable that stimulates the peroneal nerve to boost circulation, with the company claiming blood flow increases of up to 400 percent, no cords, no charger, and about 30 hours of runtime per unit. Athletes wear it after training or on long flights to cut recovery time.
They wanted 500,000 dollars for 2.5 percent, which values the company at 20 million dollars. That number became the fight of the segment. O'Leary told the founders directly he did not think the company was worth 20 million and backed out, a moment recap coverage highlighted.
The Deal That Got Done
Lori Greiner and guest shark Rashaun Williams teamed up. Their first offer was 500,000 dollars for 5 percent plus royalties, structured as 1.50 dollars per unit until repayment and then 50 cents in perpetuity. Campbell pushed back on the royalty, arguing the business needed every dollar of margin for reinvestment.
The sharks blinked, which does not happen often. They came back with a clean offer of 500,000 dollars for 5 percent, no royalty, and the founders accepted. Double the equity of the original ask, but at a still-hefty 10 million dollar implied valuation, with two sharks whose retail and investing networks fit a consumer recovery product.
Recovery as a Team Sport
The smartest thing about Firefly's position is that it sells to organizations, not just individuals. Locker rooms buy in volume and rebuy constantly because the device is disposable by design. That is where the 1,300 team figure matters: it represents recurring institutional demand that does not depend on TikTok trends.
The consumer side has grown since the episode, with the company reported as an official recovery partner of USA Boxing and its store now organized around starter and travel packs for regular athletes. The Olympic-medalist endorsement and the as-seen-on-Shark-Tank banner do the marketing work, while the product itself remains simple enough to explain in one sentence.
Firefly net worth in 2026
The valuation numbers on record are the founders' 20 million dollar ask and the 10 million dollars implied by the closed deal at 5 percent. No audited figures have been published since.
Given the institutional customer base and the consumable revenue model, the deal-implied 10 million dollars is the defensible anchor, and anything higher is speculation. What is verifiable is operational: inventory for sale, active partnerships, and a growing retail lineup, which is more than many Season 16 companies can already say.
Where Things Stand Now
Firefly pitched at 20 million dollars, took a royalty-free 500,000 dollar deal from Lori Greiner and Rashaun Williams at 5 percent, and kept doing what it did before the show: supplying recovery bands to a large share of American pro and college sport while building its consumer channel.
In 2026 the answer is yes, comfortably. If you came here after seeing the strange knee band on an athlete's leg during a broadcast, the company behind it is alive, shipping, and selling direct from its own site.
