AI Therapy
One in five adults struggles with their mental health each year and many will never see a therapist. Costs are high, waitlists are long, and stigma is still a real barrier for people to not seek help. Suicide is one of the leading causes of death for young people. Therapy works, but it doesn't scale.
We're building safe AI for mental health support that's clinically as effective as the best human therapists — accessible to everyone, at a fraction of the cost, and available anytime. We've recently had a major breakthrough. In our clinical research, we're now seeing significant improvements in anxiety and depression symptoms after just 2 weeks of use. And we receive daily messages about how Sonia is changing lives.
We're a 6-person team in San Francisco, backed by Y Combinator, Moonfire, and founders of Verkada, Reddit, and Instacart.
Sonia is an AI-native product — and our clinical research is what makes it trustworthy. We've already run clinical trials showing significant symptom reduction in anxiety and depression, and we're just getting started. We need someone to own and lead our entire research program: designing and running clinical trials, driving our FDA regulatory strategy, conducting safety research, publishing in peer-reviewed journals, and building the evidence base that establishes Sonia as a clinically validated treatment. You'll also co-write grant applications with our academic collaborators to secure research funding from federal and foundation sources.
This is a high-ownership role. You'll set the research vision for Sonia by shaping what we study, how we study it, and how we communicate our findings to regulators, clinicians, and the public. You'll work directly with the founders — who are deeply involved in AI research — and collaborate with leading academic research partners in the US and Europe.
We're kind to each other, we work hard, and we are thoughtful about what we're building. We're deeply mission-driven — we believe everyone deserves access to effective mental health support, and that belief shapes everything we do.
We're an AI-native team that believes a small, focused group can achieve what previously required 100 people. Everyone here has high ownership and real impact on the direction of the company. At the same time, we take clinical evidence and safety extremely seriously — moving fast never means cutting corners on rigor.
Our core team works 6 days a week together in our office in downtown SF. This role can be remote or hybrid, but we value regular in-person collaboration and prefer in person work.
Our sole focus is to build a safe AI therapist clinically as effective as the 99th percentile human therapist and to make mental health support accessible to anyone. After 12 months of exploring all sorts of architectures, form factors, and approaches, we have recently had a major breakthrough. As of a few weeks ago, we now have a version with which we are starting to see very significant clinical outcomes in the form of GAD-7 (anxiety score) reductions even just after 2 weeks of using Sonia. We are receiving messages daily of how it’s changing people’s lives. We’re just at the start and there is still so much to do and build. Now it’s time to move fast and scale the team.
