SHOW UP
STRONGER.

Circl is here to protect the cognitive resilience of first responders, healthcare workers and military personnel so these career professionals show up stronger everyday.

A different kind of plan.

Circl has a different kind of plan for implementing a proactive “better brain” strategy across your organization. Our technology, provided as a low-cost subscription service, makes it much easier for you to realize the direct benefits of better brain health.

Advantages of our plan include:

Strengthened individual and team mental resilience

Improved decision-making and job performance

Fewer lost days due to medical leave

Less service disruption and administrative burden

Enhanced public safety

Protection of training investments

Integration of physical and mental health

Better brain health is within reach.

With Circl, cognitive check-ups are quick and easy — only 4 minutes per week. Analyses are instantaneous. Our program is completely self-paced and self-directed. We deliver exquisite insight into your brain health and performance and recommend ways to improve.
Our brainwave measurements make brain health:
  • Visible see what’s happening, trending
  • RELATABLE understand the science
  • Manageable take action, as needed

Change the trajectory of harmful trends.

Your brain adapts dynamically to changing states of function. At first, this change occurs imperceptibly. Over time, it may become more evident. Routine checks detect when brain performance trends become a concern or unhealthy.

Our commitment to you.

Privacy, security and encryption.

At Circl, we believe that your trust is our most valuable asset. That's why we're committed to complete transparency in how we handle sensitive brainwave data. We collect brainwave data solely for the purpose of providing personalized brain health insights and recommendations.

Trustworthy protections.*

Brainwave data is encrypted using state-of-the-art protocols in transit and at rest. Every Circl policy has security as its foundational principle.

The only identifier in our system is a 26-digit randomly generated code. This numerical code simply associates test data to a user account. Circl doesn't have the ability to associate test data with you.

Importantly, our secure analytics engine is required to make raw test data readable. Without processing data through our analytics engine, test results are unintelligible.

*Encryption methods include Transport Layer Security (TLS) for data in transit and 256-bit AES security for data at rest (stored on servers). We periodically update our security practices to conform with Microsoft recommendations.

Innovation.

Circl is a pioneer of mobile neurotechnology. Our ability to bring the advantages of established neuroscience out of the lab and into everyday life has revolutionized the management of brain health. Circl innovations include:

Brain measurement science.

As our brains constantly evaluate visual stimuli it produces an electrical current at the scalp. Circl measures this signal of brain activity to assess cognitive health and performance.

The embedded animation is a simulation of a test. This example is provided for illustration purposes only. Actual testing is structured as a series of 1-minute mini-sessions.

Test scores are analyzed and delivered instantly, they include:

  • Brain Score measures “cognitive energy” and the ability to process information.
  • Brain Rank compares a personal score to everyone else in a cohort.
  • Power calculates how many brain cells are firing in synchrony to process visual stimuli.
  • Reaction measures brain speed— how fast it recognizes and processes what the eye sees.
  • Brainwave Response charts brainwaves in response to visual information.

Improve personal and organizational resilience.

The threat of suffering a concussion, burnout, or PTSD can weigh heavily on employees. The psychological stress of worrying about the possibility of injury can negatively impact team performance and organizational resilience, just as the actual conditions would.

By providing resources to support employee well-being, Circl helps organizations promote a culture that prioritizes both health and performance.

Frequently Asked Questions.

Is the Circl headset safe to wear?

Yes, the Circl headset utilizes the same technology used in neuroscience labs for decades. The headset is a passive recorder of the electrical activity of your brain, it does not emit harmful energy in any form.

How accurate is the Circl test?

Circl is a world leader in mobile EEG digital signal processing. In technical terms, we detect brainwave data with an amplitude to 3 millionths of a volt with millisecond accuracy. The Circl headset measures your brainwaves more accurately than a heart rate monitor measures your heart rate.

Who can see my brainwave data?

Only you or those you specifically decide to share the information with such as a family member or physician. Circl complies with all relevant privacy laws in the markets where our technology is available.

What if my brain performance keeps changing or going down?

It’s natural to have daily ups and downs in brain performance. There are many biometric and lifestyle factors that affect cognitive function. Talk to your doctor if your brain performance continues on a downward sloping trend over a prolonged period of weeks or months. A persistent negative trend is a concern and indicates a potential risk of a significant brain health issue.

What is brain health?

Brain health relates to cognitive function, resilience, the ability to process information, regulate emotions and maintain good physical health. From a mental health perspective, your work and personal lives are one.

Why is it important?

Brain health is deeply rooted to living life to its full potential and to life satisfaction. It directly affects our ability to perform at work, enjoy a social life and take pleasure from intellectual pursuits.

Join our healthy
brain community.

Fighting wildfires taught me the raw power of mental resilience. As a neuroscientist who studied brains at a cellular level, I saw untapped potential to bring neuroscience research tools into everyday life. My journey as an entrepreneur and father deepened my commitment to this vision. At Circl, we're transforming these insights from the frontlines, the lab, and real life - into practical tools that make mental resilience and health accessible to all.
