Transforming GI Health with AI-Powered Precision
At ProteusDx™, we are redefining gastrointestinal care with AI-enhanced smart capsules that make diagnostics faster, less invasive, and more precise. Our mission is to advance GI health across humans, companion animals, and performance horses.
ProteusDx™ was born from the vision of FirstVitals® to close the gap between early detection, targeted treatment, and ongoing monitoring. Our platform equips clinicians and veterinarians with advanced tools that improve outcomes while reducing the burden of traditional endoscopy.
Ready to shape the future of diagnostics?
Why We Exist
Conventional GI diagnostics rely on scopes, sedation, and high costs, delaying critical decisions and limiting access to care. ProteusDx™ replaces outdated methods with precision-engineered smart capsules that detect disease, deliver targeted therapy, and monitor healing without disrupting patients, pet owners, or providers.
From chronic GERD in humans to gastric ulcers in performance horses, ProteusDx™ delivers a cross-species solution to a universal challenge: making gastrointestinal care faster, safer, and more effective.
Our Approach
AI-Powered Precision
Our onboard algorithms analyze images in real time, flagging abnormalities and providing clinicians with immediate, actionable insights.
Non-Invasive, High-Value Diagnostics
ProteusDx™ capsules require no sedation or scoping, enabling advanced GI diagnostics in clinics, barns, and even at home.
Modular and Future-Ready
Designed to evolve, the ProteusDx™ platform seamlessly supports diagnostic (ProteusDx™), therapeutic (ProteusTx™), and monitoring (ProteusAi™) applications.
Our Team
Led by healthcare veterans, GI specialists, and engineers with deep expertise in capsule endoscopy, our team unites clinical excellence with technical ingenuity. We are building a future where diagnostics are intelligent, personalized, and accessible-empowering earlier detection, targeted therapy, and better outcomes across humans and animals.
