Picky Bars

Picky Bars makes energy bars and other food for endurance training, originating in a home-kitchen project by professional triathlete Jesse Thomas, runner Lauren Fleshman and runner Steph. The brand says the founders sought a bar that combined real-food ingredients with fuel suitable before, during and after exercise. In a 2021 company announcement, Picky Bars said it joined the Laird Superfood family; that is a dated ownership statement, not a fresh corporate filing.
