Healthcare teams face the same bottleneck: information is scattered across EMR screens, scanned PDFs, and faxes - or simply stuck at other sites.
Patients.app finds patient charts nationally and fills every missing piece in your pre-op charting - so your OR runs on time, every time.

Ambulatory Surgery Centers (ASCs)
HOW WE HELP:
We prevent cancellations and automate pre-op workflows without adding staff. We find patient data across the country and use AI to screen records for surgical readiness, saving 30-60 minutes per case.
Our models auto-generate complete intake and anesthesia reports. This speeds nursing review and flags missing labs, clearances, and surgical risks, before they delay care
THE IMPACT:
01
More stable OR scheduling
02
Fewer Cancellations
03
Fewer wrong-site surgery events

Transplant Centers
HOW WE HELP:
We help grow your transplant program. We identify and prepare transplant candidates faster—without adding staff. Our AI scans thousands of pages across EMRs, PDFs, and scanned documents to flag key criteria, surface contraindications, and highlight strong candidates based on your center’s guidelines.
We generate Review Committee reports, fill UNOS and TIEDI forms, and guide patients through the process with support from trained transplant recipients. Clinical oversight is provided by Dr. Eliot Heher (former Director of the Kidney Transplant Program at MGH).
THE IMPACT:

more waitlist additions
40%
more living donor evaluations

Health Startups
HOW WE HELP:
We can power your health-tech product with clinical intelligence via API. We create custom data pipelines, auto-annotate patient records, and surface signals you need (eligibility, risk, outcomes). You don’t need to build and maintain AI infrastructure.
WHAT YOU CAN DO:
Extract and structure clinical data from EMRs, faxes, PDFs, and HIEs.
Leverage domain-tested large language models and evaluation infrastructure. Accelerate time to market with pre-built modules for note drafting, coding support, prior authorization and more.
Used onsite with over 8,000 hours of human validation, our AI is built for performance in high-stakes settings. Scale confidently with guidance from top AI researchers, physicians, and compliance experts.

Clinical Teams
HOW WE HELP:
Our models are adaptable to any clinical workflow where you are currently staffing people to find and curate information. We unifies records from EMRs, faxes, scans, and PDFs into structured, specialty-specific views. It automatically extracts key findings, flags missing workups, reconciles inconsistencies and identifies mistakes. This means less manual chart chasing and wrangling IT departments for customizations.
Our platform plugs into your EMR and taps into external systems to find information about your patients from referring sites. We can deploy on premises on local cloud instances to ensure data stays within your environment.
USE CASES:
Faster workup and eligibility screening for specialized surgeries
Automated registry and quality reporting
More complete coding and risk adjustment
Early trial matching and assessing guideline-aligned care
