Unlock your potential.

We develop neurotechnology to help you do just that.

Before Halo, our founding team spent more than a decade developing the world’s first closed loop neurostimulation device for epilepsy patients.

After achieving unanimous FDA approval and changing the lives of thousands of epilepsy patients, they began their next challenge and founded Halo Neuroscience in 2013.


Halo Neuroscience is a team of doctors, neuroscientists, athletes, engineers, and designers with a passion for the brain. We're backed by some of Silicon Valley's top venture capital firms.
