Company profile
researched Aug 2026Joon Health (legal entity Joon App, Inc.) operates a pediatric behavioral health platform built around paired parent and child mobile applications. The child-facing app uses an AI pet companion that reminds children of daily chores and routines and keeps them motivated through game mechanics, while the parent-facing side provides organization tools, insight into what may be affecting their child, intervention strategies, and personalized recommendations based on the child's interests. The stated aim is to establish consistent household routines and build longer-term life skills such as independence and self-directed task completion.
Beyond the apps, the company offers a tiered support model: families can start independently with the apps, add on-demand parent coaching, and be referred to in-network therapists or integrated therapy for more complex challenges. The clinical program is directed by Dr. Joe Raiker, Director of Clinical Strategy, described as a child psychologist with 50+ publications and 3,000+ citations, a former Chair of an ADHD Special Interest Group, a CHADD Young Scientist Research Award recipient, and previously a behavioral scientist at Twill (acquired) and an associate professor at Florida International University. Joon Certified Coaches are recruited and trained by Dr. Raiker, and the company states that nearly all coaches are licensed therapists or hold a master's or advanced degree. Coaching is offered in session-based or asynchronous formats.
User testimonials on the company's site reference children with ADHD, autism spectrum disorder, and oppositional defiant disorder, and cite uses spanning chores, morning routines, homework and other focus tasks.
Business model
Consumer-facing digital health service: free sign-up for the parent and child apps, with additional layers of paid-style support including on-demand parent coaching, session-based or asynchronous coaching programs, and referrals to in-network therapists for integrated therapy.
Free entry point through the parent and child apps, with coaching (on-demand, session-based or asynchronous) and access to integrated therapy or in-network therapist referrals as additional services.
Traction
The company reports supporting more than 1 million families and a 4.8/5 rating from over 6,000 families. It publishes an eight-week observational study reporting, based on parent reports, a 30% reduction in disruptive behaviors, 73% reporting reduced arguments with their children, 89% finding Joon easy to use, and 90% enjoying it and willing to recommend it. A randomized controlled trial comparing Joon with an attention control on behavior, executive functioning, parenting stress and internalizing symptoms over eight weeks is also described.
