Built on FHIR R4 from the first line.
Not a relational schema with FHIR bolted on later. Every clinical fact, a diagnosis, a medication, an observation, is stored discrete, coded, and portable, so a record means the same thing inside Lemma as it does anywhere in the national network.
A full participant in India’s health network.
Most systems do one role. Lemma is designed for all three: push records as a Health Information Provider, pull records from other providers as a Health Information User, and hold a patient-controlled vault as a Health Repository Provider.
Every visit becomes a record the patient actually owns.

The patient
ABHA-linked, theirs for life
Security that’s structural, not a badge.
Multi-tenant isolation
Row-level tenant scoping on every query. One clinic’s data never crosses into another’s.
Encrypted end to end
Encrypted in transit and at rest, with secrets managed, not hard-coded.
Role-based access
Every action is scoped to who you are. Clinical data is never open by default.
Insert-only audit trail
Every change is recorded and nothing is silently overwritten, a full, append-only history.
AI clinical-safety guardrails
AI proposes; the clinician confirms. No autonomous diagnosis or prescribing. Allergy and interaction checks run before sign-off.
Consent by design
Purpose-specific consent is recorded for every data use, with erasure built into the model.
Your patients’ data stays in India.
Patient data is processed in AWS ap-south-1. Lemma is designed for DPDPA compliance, with purpose-specific consent and erasure built into the data model from the start.
Run like a tech company.
Deployed on AWS in ap-south-1, App Runner, ECS Fargate, RDS PostgreSQL, and S3, with versioned migrations, recorded architecture decisions, and audit trails behind every clinical action.
Evaluate Lemma for your hospital.
We’re glad to walk security, architecture, and ABDM readiness through your team.
