# Rarebird, Inc.

> Rarebird is a New York and San Leandro-based specialty coffee company that replaces caffeine with paraxanthine (Px), the natural metabolite your body turns caffeine into. Founded by bioengineer Dr. Jeffrey Dietrich, Rarebird uses a patented reverse-infusion process to load 60mg of Px into single-origin Colombian decaf beans, promising alertness and focus without the jitters, anxiety, cortisol spikes, or wrecked sleep. Backed by Y Combinator, AgFunder, First Round Capital and the National Science Foundation, Rarebird is trying to make Px 'the third coffee' - a category alongside regular and decaf.
