Rejoy Health is building the AI care team for clinics: an AI scribe, receptionist, interpreter, and coder in one HIPAA-compliant suite. Meet founder Rituraj Yadav and see how the platform reached a $125M valuation.
Every missed phone call at a clinic is a patient who never gets seen. Every hour spent finishing charts after the last patient leaves is an hour clinicians don’t get back. Front desks are understaffed, schedules have holes, and doctors are still coding visits and looking up drug interactions while the next patient waits in the exam room. This is the daily reality for thousands of clinics across the United States, and it’s exactly the problem Rejoy Health was built to solve.
Rejoy Health describes itself as the AI care team for clinics: a suite of AI workers that run clinic operations end to end, from the first phone call in the morning to the last clinical note at night. Rather than adding another standalone chatbot to a clinic’s tech stack, Rejoy replaces the busywork that eats into clinical time, so doctors, nurses, medical assistants, and front-desk staff can focus on care instead of admin.
Meet the Founder: Rituraj Yadav
Rejoy Health was founded by Rituraj Yadav, who serves as CEO, alongside co-founder Ritu Ranjna. Rituraj studied at Columbia University in New York and previously worked as a Senior Engineer at Facebook AI Research, where he gained firsthand experience building large-scale, reliability-critical systems. He and Ranjna founded Rejoy Health after being accepted into Y Combinator’s Winter 2021 batch.
That combination of deep AI engineering experience at one of the world’s largest technology companies and a world-class education shapes how Rejoy Health approaches healthcare AI. Rather than focusing on flashy demos, the company is building reliable infrastructure designed for real-world clinical environments, where accuracy, consistency, and reliability matter far more than they do in consumer technology.
In healthcare, an AI system cannot simply be impressive. It has to work correctly, consistently, and safely, because the consequences of an error can be far greater than in most other technology applications.
What Rejoy Health Actually Does
Rejoy Health isn’t one product. It’s a full suite of AI workers, each built for a specific job that currently eats into a clinician’s day.
AI Receptionist. Covers the front desk 24/7. It answers calls, handles routine questions, and books, reschedules, or cancels appointments without putting anyone on hold. Nights and weekends stay covered, which means more patients get on the calendar instead of hanging up on an unanswered line.
AI Scribe Turns the conversation during a visit into a structured clinical note in real time, so clinicians can walk out of the room with the chart already done instead of finishing documentation after hours.
AI Interpreter. Provides live language interpretation between clinicians and patients in English, Spanish, French, Chinese, Korean, and more, removing a major barrier to care for non-English-speaking patients.
RejoyGPT and Clinical Decision Support. Gives journal-backed answers to clinical questions, suggests next steps, and helps draft notes, referral letters, and patient education materials while the patient is still in the room.
AI Coder. Suggests ICD-10 and CPT codes based on the visit, so billing goes out cleaner and claims move faster with fewer denials.
Medical Search Engine and AI Study Companion. Rounds out the suite with a clinical-grade search tool for guidelines, journals, and drug data, plus an exam-prep companion for medical and residency board exams.
Rejoy positions the whole suite as easy to adopt: doctors, nurses, medical assistants, and front-desk staff can start the same day with almost no training, and one login scales from a solo practice to a full health system.
A Milestone Year for Rejoy Health
Rejoy Health’s traction has scaled quickly since its 2021 Y Combinator launch. By 2024, the company had raised funding at a $125 million valuation, with the round tied to backing from investors including Y Combinator, Google, and Microsoft. The company said the capital would go toward hiring more AI engineers and expanding the GPU infrastructure behind its healthcare-specific language models.
Today, Rejoy Health is trusted by more than 40,000 clinicians at health systems including Johns Hopkins Medicine, Stanford Medicine, NYU Langone Health, UCLA Health, NewYork-Presbyterian, Massachusetts General Hospital, Mount Sinai, and Harvard Medical School. On MedQA, the USMLE-style benchmark used to evaluate medical question-answering, Rejoy reports a 99.4% accuracy score, ahead of GPT-5 (97%), GPT-4 (89%), and GPT-4o (88%). That comparison is the basis for its “more accurate than ChatGPT” positioning.
Frequently Asked Questions
What is the valuation of Rejoy Health? Rejoy Health raised $15 million in August 2024 at a valuation of $125 million. Since then, the company has expanded its product offering and grown its revenue, so its current valuation could potentially be significantly higher than its 2024 valuation.
Is Rejoy Health HIPAA compliant? Yes. Rejoy Health is HIPAA-compliant by design, with healthcare-grade encryption, security, and access controls built into every tool in the suite, from the AI Scribe to the AI Receptionist.
How is Rejoy Health different from ChatGPT or a general AI assistant? Rejoy Health is purpose-built for clinical work rather than general conversation. On MedQA, the USMLE-style benchmark used to test medical question-answering, Rejoy reports 99.4% accuracy, ahead of GPT-5 (97%), GPT-4 (89%), and GPT-4o (88%). It’s also HIPAA-compliant out of the box, which general-purpose tools like ChatGPT are not built for.
How long does it take a clinic to get started with Rejoy Health? Rejoy is designed for same-day adoption. Doctors, nurses, medical assistants, and front-desk staff can all start using the platform the same day, with almost no training required.
Does Rejoy Health work for solo practices, or only large health systems? Both. Rejoy Health runs on a single login that scales from a solo practice to a full multi-location health system, so the whole team works inside the same system regardless of practice size.
Who backs Rejoy Health? Rejoy Health is backed by Google, Microsoft, NVIDIA, and Y Combinator, support the company says goes toward building the clinical-grade AI models hospitals can rely on.
Why Rejoy Health Isn’t Just Another Healthcare Chatbot
The healthcare AI space is crowded with point solutions: one vendor for transcription, another for coding, another for patient messaging. Rejoy’s pitch is consolidation. Instead of a clinic juggling five different logins and five different vendor relationships, one suite covers scribing, coding, reception, interpretation, clinical lookup, and exam prep.
Just as important is how the platform is built for a regulated industry. Rejoy Health is HIPAA-compliant, with healthcare-grade encryption, security, and access controls, a baseline requirement that general-purpose AI tools like ChatGPT were never designed to meet out of the box. And the “you stay in charge” framing is deliberate: Rejoy is positioned as an assistant that hands decisions back to the clinician, not a system that makes clinical calls on its own.
Rejoy Health is tackling one of healthcare’s most persistent operational problems: the gap between how much clinicians have to do and how many hours are actually in a clinic day. Under founder Rituraj Yadav, the company has grown from a 2021 Y Combinator startup into a platform valued at $125 million and used by tens of thousands of clinicians at major U.S. health systems. For clinics drowning in unanswered calls, unfinished notes, and slow billing, Rejoy Health’s AI care team offers a way to book more patients, see more patients, and chart less, without adding headcount.
