About Rarebird

Our Story

Jeffrey Dietrich

Rarebird was founded by Jeffrey Dietrich, whose Ph.D. thesis and ventures in bioengineering led him to a concept that changes coffee as we know it. It’s an advancement that provides health benefits for the mind and body - which is good news for, well, everybody.

Caffeine has been the marathon fuel for the human race for a long time — from the Enlightenment through the technological revolution. It’s been a great ride, but if we’re being honest... isn’t caffeine increasingly incompatible with modern life?

So we crafted a coffee with Px instead of caffeine. That means fewer downsides like the caffeine jitters, anxiety and poor sleep. Px coffee is smarter all around, delivering perks like smooth energy and refined focus. Plus, with a shorter half-life, Px is far less likely than caffeine to disrupt your sleep.

Quotes
I was in my late twenties when I realized that traditional coffee wasn’t working for me any more. The morning cup that used to help me get ahead was now leaving me behind. Anxiety and jitteriness became the new normal. The problem wasn't actually coffee, or even caffeine; the problem was partially me – I'm genetically predisposed to be caffeine sensitive – but also my life had become really, really stressful and I wasn't taking care of my own mental health. Caffeine was just a magnifying lens for my stress.
I tried all the coffee alternatives out there, but let’s be honest, anything without caffeine doesn’t work and I love the ritual of brewing a cup first thing in the morning. So rather than try and beat coffee I decided to reimagine what it could be. That idea led me to the world's first true caffeine alternative, paraxanthine (Px), and to think of coffee as the ultimate mental wellness drink, not just a cup of joe.Jeffrey Dietrich, PhDFounder and CEO
