About Rarebird
Our Story
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.
