Galen AI logo

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!

Gantto

Better Microsoft Project.

Gantto was conceived to fill one obvious gap in our weekly management routine. Each week we would collect status information based upon what was really happening inside the organization and then update our project models to reflect and digest the changes. Then we would spend tedious hours manually creating presentations based upon the same underlying project data that we had already updated. After a long search for a good solution we set out to create our own. Gantto is a play on words on gantt chart – the most commonly used visual representation of project schedules. Gantt charts take their name after Henry Gantt, who popularized them in 1910. In reality they were originally conceived by Karol Adamiecki, a Polish economist / engineer who invented them in 1896 and named them harmonograf.
