MindBridge
Claude-powered AI mental health companion with mood tracking, CBT-aligned exercises, and 78% 30-day retention. Shipped in 5 weeks.
The challenge
A digital health startup wanted to extend the impact of therapy between sessions — without replacing therapists. The app needed to feel safe, clinically appropriate, and genuinely useful; not another journaling app with a chatbot bolted on.
What we built
Claude-powered companion for between-session support: structured mood check-ins, CBT-aligned exercises surfaced contextually, and automatic crisis detection that routes to emergency services. Therapist visibility dashboard with session summaries. Built on React Native with Expo for cross-platform launch on day one.
