About Us
We're transforming gut health by building science-backed, personalized solutions for people who’ve been overlooked or underserved by traditional medicine.
At Claisen, we believe that chronic digestive issues like GERD deserve more than generic advice and symptom-chasing treatments. Our mission is to combine clinical insight, cutting-edge technology, and real patient experience to deliver care that’s precise, empathetic, and actually effective.
This isn’t just about managing symptoms — it’s about giving people their lives back.
Our Commitment to Your Health
Formulated by Doctors
Clinically informed
No pseudo-science junk

FDA approved drugs only
Meet the Jain Brothers
At Claisen, our work is deeply personal. Aditya Jain, our Chief Medical Officer and a current M.D. candidate at Harvard Medical School, has lived with GERD for as long as he can remember. Navigating the healthcare system and experimenting with countless solutions, he experienced firsthand how frustrating and isolating chronic digestive issues can be. That journey fuels his relentless pursuit to bring evidence-based, empathetic care to those who suffer silently.
Rishab Jain, our Chief Executive Officer, believes entrepreneurship isn’t just about innovation: it’s about impact. With a background in biotech and AI, he’s committed to building scalable tools that actually improve people's lives. Together, as brothers and co-founders, we started Claisen to reimagine how gut health is understood, managed, and treated... with science, compassion, and relentless drive.
