What is Firefly Recovery?
Firefly Recovery is a portable device that gently stimulates the peroneal nerve to promote blood flow and speed up recovery time for athletes.
Firefly Recovery's Shark Tank Pitch Recap
Anthony Kjenstad and Lauren Campbell pitched Firefly Recovery, a portable recovery device for athletes, seeking $500,000 for 2.5% equity. The device uses peroneal nerve stimulation to increase blood flow and reduce soreness. The Sharks questioned the high valuation of $20 million, especially given the company's sales figures. After multiple offers and counters, Lori Greiner and Rashaun Williams offered $500,000 for 5% equity, with a royalty of $1.50 per unit until they recoup their investment and $0.50 in perpetuity thereafter. The founders countered with 3.5% equity. The Sharks then changed their offer to $500,000 for 5% with no royalty. The founders ultimately accepted this offer.
