About Us

Sunlight is a requirement for human health, like food, water, and air - yet the public is widely unaware.

We envision a world where every human has proper light access.

Peter Forhan

Founder & ceo

Peter is an avid inventor; obsessed with the practical applications of light. His infatuation with light began in 2019 after graduating from the University of Michigan with a degree in Materials Engineering. Before the pandemic, Peter invented Halo, an ultraviolet hand sanitizer. At the onset of COVID-19, he quickly scaled the invention into a company. Through a deliberate and recreational review of clinical reviews, Peter stumbled across an old discovery that changed his life. Sunlight is a physiological requirement for human cells and modern humans are chronically sunlight deprived. Today, Peter is committed to building the vision of Niels Finsen; Phototherapy access in every home. Nevertheless, I believe implicitly that in the future use will be made of this new therapeutic agent [Light], and the proof experiment once made, it will be easy to carry it out practically under the form of Light Baths; and lastly, to determine whether they are to be blue, violet, or red, the variations in their strength and duration, and whether natural or artificial.” - Finsen, Phototherapy, 1896

Joseph Asker

Director of Operations

Joey is a health-conscious people-person who was able to cure his arthritic elbow pain with light therapy. This came after having been told by surgeons and physical therapists that his arthritic elbow pain was just something that he would have to deal with for the rest of his life. The astonishingly fast and effective light therapy treatments shattered Joey’s perspective of our healthcare system; motivating him to drop everything and work towards redefining our health paradigm by bringing light to health. Before Joey saw the light, he obtained his BA from University of Michigan in 2018 with a dual degree in Sociology and Biopsychology, Cognition, and Neuroscience. Joey has extensive startup experience, having founded two companies with Peter post graduation. He proudly serves as JustLight’s Director of Digital Operations.

Noah Maike

Design Engineer

Noah is a curious engineer who became fascinated with the implications of light on our health after meeting with Peter in early 2021. Noah sees the disconnect between the scientific significance of light therapy and its accessibility for consumers and he’s dedicated to closing that gap. Noah works closely with the design, manufacturing, and science teams to blend the three and deliver beautiful, scientifically-backed devices to consumers at scale. Noah started his career with JustLight while still in engineering school, working on the design of Sunflower in between classes and homework. He will graduate with his degree in Mechanical Engineering from the University of Michigan in April where his studies have focused on mechanical design and manufacturing
