We’re on a mission to improve the lives of people with mental health conditions through technology and services.

Our vision is one day every person with a mental health condition will receive the care that they need.

We believe that mental health should be treated just like any other health condition. That’s why we begin with primary care. We arm doctors with the right tools to diagnose patients and easily refer them to a trusted network of mental health providers.  

Our collaborative, tech-enabled approach connects people to the right care at the right time.

We partner with health plans and systems to facilitate access to personalized care and enable virtual collaboration between providers to ensure the best health outcomes.

We put human touch back in healthcare.

For both providers and patients, navigating the mental health space is difficult and confusing. That’s why we employ trained specialists and clinicians supported by our application to provide ongoing support for providers and patients to improve the experience and outcomes.
