Our Mission

OptoCeutics develops future solutions to brain health utilizing non-invasive light technologies with the aim of providing better therapeutics for patients and families.

Our Vision

With collective efforts from research, clinicians and patients, OptoCeutics works to create a world where mental illness is better understood, treated and ultimately prevented.


Our Goals

OptoCeutics solutions are developed to meet these three goals:

  • Patient-centric

    We engage in a dialogue with patients, their families and practitioners early in the development to be aligned with their needs and preferences.

  • Non-invasive

    We develop solutions that are comfortable, safe to use, and completely non-invasive.

  • Home-based Care

    The solution is to be used in the comfort of your own home. It is convenient and easily implementable in the everyday life.
