Sprout

Mental health care in the US is quietly inaccessible for most people who need it. Around 20% of the population deals with mental health challenges each year, and in 2021 alone, 42 million people sought treatment or counseling. Yet the system built to serve them is full of friction. Therapy appointments require months-long waits. Sessions cost upwards of $100 each, putting consistent care out of reach for most people. And even when someone is ready to ask for help, stigma often gets in the way before they ever make the call.

The group feeling this most acutely is adults aged 18 to 44, who had the highest rate of mental health treatment in 2021 at 23.2%. These are people who are aware they need support and are actively looking for it, but the existing options are either too expensive, too slow, or too shallow to actually meet them where they are.

The problem is not that people do not want help. It is that the path to getting it has too many barriers.

Existing solutions fall across several categories, each with distinct trade-offs:

None of them combine real therapeutic value, affordability, and an experience people actually want to come back to.

We started with a simple framing. Think about a time you stayed up late talking with a close friend about everything going on in your life, in a space where you felt completely safe being honest. Sprout is that, except it is always available, trained on cognitive behavioral therapy principles, and never judges you for reaching out at 2am.

The core insight was that mental health support does not have to feel like a clinical transaction. CBT is one of the most evidence-backed therapeutic frameworks we have, and it translates well to conversational AI. The goal was to build something that felt genuinely human-like while delivering real therapeutic value, and to wrap it in an experience that made people want to keep showing up.

That last part led us to the gamified layer. Users grow a companion from a small plant into a tree and eventually a full forest as they engage with the app and hit mental health milestones. They earn coins through consistent use that can be redeemed for real mental health services through an in-app marketplace. It sounds simple but the psychology behind it matters. Habit formation is one of the hardest parts of any wellness practice, and giving people a tangible sense of progress and reward changes the relationship they have with showing up.

Before touching Figma we spent time talking to people. Through interviews with 15 or more potential users in our target demographic, a few themes came up consistently. People needed support that was available immediately, not weeks away. They could not justify the cost of regular therapy sessions. And they were bored by existing wellness apps that felt more like digital to-do lists than actual support.

A few quotes that stuck with us:

“I need support now, not in three months when I finally get an appointment.”

“I wish there was something more engaging than just meditation apps that would actually help me work through my problems.”

Affinity mapping helped us cluster the feedback into clear design directions: cost and accessibility, trust and privacy, gamified features and motivation, companionship, habits and reminders, and personalization. Each cluster became a lens we used when making product decisions throughout the build.

From there we moved into low-fidelity wireframes in Figma, mapping out the core user flows before adding any visual detail. The design went through several rounds of iteration based on usability testing with 10 or more participants.

On the technical side, Sprout is a React Native app built with Expo, with a Node.js backend and the OpenAI API powering the conversational layer. The AI was prompted and fine-tuned to follow CBT principles across different types of conversations, whether someone is venting about their day or working through a specific anxiety trigger. For voice, we integrated the ElevenLabs API to give the companion a warm, natural-sounding voice that could read responses aloud, so users could talk through a session hands-free without losing the sense that someone was actually listening.

Text and voice both feed into the same underlying AI system, so switching between typing and speaking feels like one continuous conversation rather than two separate modes.

The gamified system required more thought than it might look like from the outside. Tracking milestones, managing coin balances, and keeping the companion's growth state consistent across sessions meant building a backend that could handle all of that reliably without it feeling mechanical on the surface. The goal was for the progression to feel earned and meaningful, not arbitrary.

The marketplace was designed as a lightweight integration layer where partnering mental health businesses could offer services in exchange for coins, creating a revenue model that actually aligns with user wellbeing rather than working against it.

Building a product in the mental health space forces you to think carefully about trust in a way that most apps do not. Every design decision, the tone of the AI responses, the way progress is framed, the language around privacy, carries more weight when the person on the other end is in a vulnerable state. Getting that right was the hardest and most important part of the work.

We also learned that gamified features only work if the underlying product is actually valuable. The coins and progression system are not what makes Sprout worth using. They are what makes it easier to keep using something that is already genuinely helpful. That distinction shaped how we prioritized features throughout the build.

Sprout is on track to launch in three to four months as part of the Buildspace S5 Cohort. The roadmap from here includes deeper usability testing, app store optimization, and partnerships with mental health organizations and wellness-focused creators. The freemium model gives us a sustainable path forward, with a premium subscription for unlimited access and the marketplace creating additional revenue tied directly to user engagement and progress.

The goal from the beginning was to make quality mental health support accessible to anyone with a phone. We think we built something that can actually do that.
