Our Story

Our history started in Colorado in 2017, when Hannah found she had allergies to corn, gluten, peanuts, soy, and dairy. She was also a competitive runner training to qualify for the Olympic Trials in the marathon, and there were no corn-free endurance sports drinks on the market. So as a registered dietitian and researcher at heart, she went to work formulating her first product that you know today as the Lemon Lime Endurance Mix. Caleb, who was pursuing his PhD in chemistry and was also a collegiate mountain bike racer, came alongside using his science background and connections in the community. Together, Flow Formulas was born. Ryan came along in 2018 offering his business marketing and finance expertise after his time at Red Bull and Harley Davidson. As the former and current Executive Team of Flow Formulas, Caleb, Ryan, and Hannah, along with some amazing partners, have grown Flow Formulas from a small commissary kitchen operation with three endurance mix flavors, to a full line of products known today as Flow Formulas.


Our Team

Hannah Reese
All things Operation and Execution, Founder & Co-Owner

Hannah is best described as jack-of-all-trades at work, but also at play. She is a lover of all things outdoors, including the Colorado Rocky Mountains, backpacking, nordic skiing, Triathlon, and cycling. A foodie at heart, her day-to-day consists of coffee, making things taste better, riding with friends, and exploring the outdoors on two legs or two wheels.

Caleb Reese
Marketing, Team Manager, Founder & Co-Owner

As a kid, Caleb enjoyed the great outdoors, spending hours exploring the woods or land behind their house in the country. Now Caleb satisfies that exploration bug on his local trails or across the country racing and going on adventures. He enjoys riding and racing with his friends, researching nerdy chemistry, and sipping espresso while eating Nutella covered waffles. After finishing his PhD in Chemistry in 2021, Caleb is now a Postdoctoral Research Associate developing recyclable polymers for sports equipment. Caleb manages the Flow Formulas Off-road team, assists with marketing, and assists with product R&D.

Ryan Mehaffey
Finance, Marketing, Sales & Co-Owner

Ryan grew up an adrenaline junkie and found his way to the mountains of Colorado where he can pursue Downhill and Enduro to the fullest. In addition to bringing strategy and business expertise to Flow, he is Founder and CEO of an organization that supports social impact business models around the globe. You can usually find him doing bike park laps or some sort of endurance related activity with his wife, son, and Siberian husky, Nika.
