Kent Yoshimura and Ryan Chen walked away from $1 million (£790,000) on national television in 2020. Robert Herjavec wanted 20 per cent of their nootropic gum company for it. They refused. Had they accepted, they would have priced the entire business at $5 million (£3.95 million).

Six years on, their brand Neuro has generated $135 million (£107 million) in cumulative sales and is now stocked in more than 20,000 stores across the United States, including CVS, Walmart and Whole Foods Market. The founders confirmed both figures during an update segment on Shark Tank Season 17, which aired on 11 March 2026, Shark Tank Blog confirmed.
