Transforming GI Health with Precision and Intelligence
At ProteusDx, we are redefining the future of gastrointestinal diagnostics through AI-enhanced, smart capsule technology. Our mission is simple yet bold: to make GI diagnostics faster, less invasive, and more intelligent-across species and settings.
Born from the vision of FirstVitals, ProteusDx was designed to bridge the gap between early detection, targeted treatment, and ongoing monitoring. Our platform empowers clinicians, veterinarians, and specialists with tools that work smarter-not harder-to improve health outcomes in humans, pets, and performance animals alike.
Why We Exist
Conventional GI diagnostics-reliant on scopes, sedation, and high costs-delay critical decisions. ProteusDx replaces outdated models with precision-engineered capsules that detect disease, deliver localized therapy, and monitor healing, all without disruption to patients or providers.
From chronic GERD in humans to gastric ulcers in horses, ProteusDx provides a cross-species solution to a universal challenge: making gastrointestinal care faster, safer, and more effective.
Our Approach
AI at the Core
Advanced onboard algorithms analyze images in real time, flagging abnormalities and assisting clinicians with immediate insights.
Non-Invasive, High-Impact
Our capsules require no sedation or scoping-enabling diagnostics in clinics, stables, and even at home.
Modular and Scalable
Built to evolve, the ProteusDx platform supports diagnostic, therapeutic (ProteusTx), and monitoring (ProteusAi) applications.
Our Team
Led by healthcare veterans, GI specialists, and engineers with deep expertise in capsule endoscopy, our team blends clinical excellence with technical ingenuity. Together, we’re building a future where diagnostics are intelligent, personalized, and accessible.
