Senior Product Designer - Mission Driven AI Startup

The Mission: ADHD & Autism Support

In the UK, nearly 1 million people are currently on waitlists for Autism or ADHD assessments. Half of them are children. These families are often at breaking point, feeling desperate and overwhelmed for years, with nothing out there to help.
We have built an AI platform designed to provide immediate, evidence-based support the moment it’s needed. We aren’t just building an app; we are building a lifeline.

You can learn more about Sylva in our 10 minute video, and BBC coverage of our earlier prototype, which we called Hazel.
