01 / The formula
What’s behind
the boost.
The lift
Paraxanthine
Caffeine-free energy powered by paraxanthine, caffeine’s primary active metabolite, delivered directly. Research suggests fewer jitters and a calmer lift than caffeine, with a shorter half-life that's less likely to interfere with your sleep.
02 / The bright side
A little pucker.
A lot of punch.
yuzu + passionfruit
Bright yuzu meets the tropical tang of passionfruit. Refreshing, citrusy, and made to wake up your taste buds.
03 / A note from the founder
Hi, I’m Catherine.
I’m building Bumper.
You care about what goes into your body as much as what you get out of it. Your energy should keep up.
Bumper came out of working 12–15 hour days and wanting exactly that: energy without the jitters or the afternoon crash. Nothing on the shelf offered what I wanted, with ingredients I trusted and in a form I actually enjoyed.
After years of building software in finance and tech, I left to build something you could hold in your hand. A small shot, made with care for the people reaching for it.
That’s Bumper. And you’re invited into the process. I’m building in public, sharing the experiments, decisions, and lessons along the way. I’d love for you to follow along.
