❌ The Problem

Over 1 billion people live with chronic illness: fibromyalgia, long COVID, POTS, ME/CFS, EDS, endometriosis, lupus, MS and many more.

• Patients spend months waiting for appointments, then get 15 minutes to explain years worth of symptoms
• The average diagnosis takes 7.6 years
• Many now turn to ChatGPT and Claude for advice, but without continuous context, the advice is generic and rarely actionable

👬 Our Story

We started building Juno after growing up with chronic conditions ourselves. Isaac waited 14 years for an eosinophilic bronchitis diagnosis. Marshall lives with ME/CFS and is still searching for something that helps. We spent the last year conducting research at Oxford and UCL to understand what makes people engage with medical chatbots, to allow Juno to ask the right questions at the right time and comprehensively understand each user’s health.

🩺 The Solution

Juno builds a longitudinal health profile from your conversations, biometrics, and medical history to provide:

• 💬 Personalised symptom advice - guidance that actually makes sense for your body
• 📊 Continuous tracking - symptoms logged automatically through natural conversation, by text or voice
• 🔍 Pattern detection - identifies triggers and patterns over weeks and months
• 📄 Appointment-ready PDFs - turn months of data into a summary your doctor can instantly understand

📈 Where we’re at (after 6 months)

• 80,000 users globally, grown primarily through our organic content
• 9,000+ five-star App Store reviews
