About Us
Each day we’re asked to carry more – more choices, more noise, more weight than our nervous systems were designed to hold. But clarity should not feel like another demand. That’s why Thea exists.
Your emotions are not flaws to fix. They are signals, alive in your voice, quietly revealing what your body is holding.
Thea is not a solution outside of you. It is a mirror, a companion, a reminder: everything you need to return to balance is already within you.
Our team
Rachelle Barrack is the Founder and CEO of Thea, a voice-AI powered platform that uses personalized sound to help people reset their nervous systems in minutes. With a background spanning music, finance, and wellness innovation, she has invested in and built companies at the intersection of empathic AI and emotional wellbeing. She created Thea from a lifelong belief in music’s power to bring clarity and calm – turning what we all feel when we hear a favorite song into a daily companion you can return to when it’s needed most.
