Mental Health, Co-Designed
Kooth partners with young people to create Soluna, a mental health resource for California youth.
Young people in the United States are facing a mental health crisis. Depression, anxiety, and suicide rates are dramatically on the rise. Yet, there are significant barriers to finding support—like the stigma around seeking therapy and the high cost of care. To provide millions of young people with the vital and early help they need, the State of California invited Kooth, a global provider of behavioral health solutions for young people, to develop a digital mental health and wellbeing platform for 13-25 year-olds. Kooth partnered with IDEO to not just create an app for young people, but actually co-design it with them. Launched in January 2024, the app, called Soluna, encompasses behavioral health coaching, interactive tools and personalized content, and is now available for free for all youth in California.

The U.S. Surgeon General named mental health “the defining public health crisis of our time,” and cited social media, online bullying, information overload, and the loneliness and isolation exacerbated by the COVID-19 pandemic as major drivers that have significant negative outcomes for youth.
In California alone, more than 284,000 youth cope with major depression. Sixty-six percent of kids with depression do not receive treatment, and between 2019-2020, the suicide rate for kids ages 10-18 increased by 20 percent.
In 2022, California Governor Gavin Newsom’s Master Plan for Kids’ Mental Health set aside $4.6 billion to increase access to mental health and substance abuse support for all California youth, the largest commitment to youth mental health ever made by a state government.
Increasingly, digital spaces are proving detrimental to youth mental health. By co-designing with youth, Kooth and IDEO set out to flip the script, creating a positive digital space for young people to safely explore their mental wellbeing.
When Kooth, IDEO, and Blackbird, IDEO’s longtime development partner, first started working on the project, the window of opportunity was narrow, and the stakes were high. The group was up against a nine-week deadline to create a working proof of concept app. Also on the line: a $188 million contract with the Department of Health Care Services (DHCS)—one that would open an entirely new line of business for Kooth.
The app needed to do more than demonstrate functionality—it needed to prove its value. To ensure that they were creating an asset that truly fit the needs of young people, the team turned to an initial cohort of 13-25 year-old co-designers who explored early features, created video diaries, and shared their questions about and experiences with mental health. These young people often gravitated toward self-service tools that helped them take action based on their feelings. With their feedback, the team created new expressions of clinically-validated behavioral health tools like journaling, breathwork and white noise—and built novel tools, such as Starboard, an expressive drawing tool and a nod to art therapy.
The team took inspiration from content the co-designers liked to consume, such as story-driven video games that enable freedom of exploration, deepened by a unifying mythology. That led them to a constellation theme, which made the experience more intriguing and playful. The co-designers also recommended a dark color palette, because they preferred exploring the app at night.
With these insights, the team refined the proof of concept, and then conducted a one-week pilot with another 50 young people across California. Their positive feedback gave the State the confidence to invest in a $188 million, four-year contract for Kooth to bring the app to a platform at scale.
Over the next year, the team engaged another 150 young people to help design, shape, and test the app. At the same time, Kooth and IDEO created a clinical oversight group, which included a pediatrician, therapists, and other clinical specialists. This group anchored the platform in the practices of Acceptance and Commitment Therapy (ACT), cultivating psychological flexibility—the mindful acceptance of positive and negative emotions. Young people are invited to complete short reflections and surveys throughout their journey with the app, which includes rigorous, science-backed measurements to assess the therapeutic benefits.
Behind the scenes, the team developed a clinical-facing service and digital platform that empowers Kooth’s peer specialists, social workers, community curators, and clinicians to support the youth experience, all while protecting privacy and confidentiality. They also navigated a complex landscape of state requirements and government legislation, ensuring that the platform could cover topics like substance abuse and gender identity, and that users could access coaching within 24 hours, and choose from a diverse set of experts.
The last step was to select a name that worked across multiple languages, trademarks, and competitor branding, and didn’t come off as a mental health service, something the youth co-designers believed was critical. IDEO and Kooth landed on Soluna, a name that alludes to the app’s presence in both the bright (“sol” for sun) and the dark times (“luna” for moon).
Now, Soluna is available for free to all youth in California, and the state has set ambitious targets for reaching all young people at scale. Soluna is a living platform that will continue to receive product and design updates for years to come, all deeply rooted in youth co-design.

“Working with IDEO enabled Kooth to supercharge the development of Soluna as a product-led initiative. With their help developing key conceptual themes, and dreaming the art of the possible, we were able to design, develop and launch at incredible pace. The result—the numbers speak for themselves—but most importantly youth in California recognize Soluna as a mental health app that speaks to them.”
