Unlock Your Potential

Our team of doctors, researchers, and neuroscientists is developing easy to use, novel, and effective neuroscience-based technology for improving brain performance in the healthy and impaired.

For now we're hard at work in the lab, but we can't wait to show you what we're working on.

At Halo, our mission is to create products and services that allow anyone to unlock their brain's full potential. We're not ready to lift the curtain quite yet, but here's a bit about what we're working on:


We're working to integrate world class neurotechnology into a form factor that is beautiful, simple, and easy to use.

Companion App

Neuroscience is complicated. Using our products shouldn't be. The Halo app makes things as easy as a tap.

Science & Safety

Our proprietary technology builds on decades of research around tDCS and TES, and has been developed for years by top neuroscientists and doctors. More than 1,000 people have used our technology and participated in double-blind studies managed by a third party investigator. We've ensured that Halo's technology is effective and meets the absolute highest standards of safety.

In-house research

We've conducted thousands of hours of double blind studies with more than 1,000 people to prove efficacy, reliability, and safety.

External research

Our work builds on decades of academic research surrounding tDCS and TES.

Developed by experts

Our founding team brings an MD, a Ph.D, and a combined 30 years in neuroscience to Halo. Their previous company—Neuropace—changed the lives of thousands of people suffering from epilepsy.
