Galen AI

Personal AI healthcare agent, powered by clinical and wearable data.

Galen is an AI-powered personal healthcare companion. We enable patients to securely connect their medical records from over 800 healthcare institutions across more than 12,000 locations in the United States, United Kingdom, and Canada. We also connect with over 20 popular wearable devices including Apple Watch, Fitbit, and Dexcom, bringing all your medical records and health data into one unified space. We founded Galen because for over four years, Viraj struggled to navigate several conditions related to chronic low back pain. He often found himself waiting weeks for responses from his care team, received little guidance or education about new diagnoses, and was overwhelmed trying to manage overlapping conditions and medications. His experiences are not unique. Our healthcare system is overloaded and fragmented, and often, patients are left to navigate their care on their own. Everyday there are nearly 1 billion health-related Google searches, but the responses to such queries are generic and impersonalized, because the searches lack any insight into a users personal health background. By leveraging your own data and state-of-the art LLM memory capabilities, Galen delivers personalized insights, proactive health recommendations, and 24/7 on-demand medical support — empowering patients to be an active part of their health team. We are a consumer app in beta testing and will be available on the App Store soon!

💥 The Problem

For 4+ years now, I’ve struggled to navigate several chronic low back conditions. I often waited weeks for responses from my care team, received little guidance about new diagnoses, and felt overwhelmed trying to manage overlapping conditions and medications.

I found myself turning to ChatGPT. A lot. And quickly, Priyanka and I realized my experience is not unique…it’s the norm. Our healthcare system is overloaded and fragmented, doctors are pressed for time, and patients are expected navigate the majority of it alone.

Increasingly, patients are trusting LLMs with their health questions, but these tools weren’t built to understand a person’s full clinical history, wearable data, and evolving health context, so they fall short of delivering truly personalized insights.

🧠 Our Solution

Meet Galen AI — our AI-powered solution to make high-quality, personal medical support accessible to everyone. No more screenshotting your records and uploading them to ChatGPT. No more WebMD rabbit holes about your symptoms. No more waiting months for your next doctor’s appointment.

All Your Medical Data in One Place

Galen securely integrates with Apple HealthKit to connect directly to your medical records, allowing you to unify health data from all your providers and institutions in one place.

It also syncs with your Apple Watch to bring in daily fitness and activity data, with support for 20+ additional wearables coming soon.

As you share new symptoms and health updates, Galen keeps track and continuously learns about your evolving needs, providing long-term support.

Talk to Your Health Data

Once your records are connected, you can:

  • Receive clear, comprehensive summaries of your medical history
  • Ask questions about and uncover patterns in your health data
  • Understand new symptoms in the context of your existing conditions
  • Receive tailored insights about medication side effects or interactions, comorbidities, and treatment impacts

🌲 Meet the Team!

We met working on a class project at Stanford and haven’t stopped building together since.

Priyanka, originally pre-med, conducted clinical and biocomputation research at Stanford SAIL, Cleveland Clinic, and UCLA, and worked as a software engineer at Roche. I worked as an engineer at Optiver and quantitative trader at IMC Trading before developing a strong interest in healthcare through my personal experiences.

We both pursued a BS/MS in Computer Science from Stanford and have collaborated on several AI and healthcare projects, including a mobile app for cancer patients with the Stanford Center of Biodesign.

We’d love to hear from you; please reach out if you want to chat → founders@galenai.com. Thank you!
