Four pillars
Built around the four things every hospital actually does.
Pillar 01
Every encounter on one timeline.
Front desk, OPD, IPD, ICU and OT: every clinical encounter lands on one lifelong, queryable, FHIR-native timeline.
- Front desk, OPD, IPD, ICU and OT on one record
- FHIR-native and lifelong, from first visit onwards
- Queryable history, allergies and results

Pillar 02
Orders that check themselves.
Orders, prescriptions, dispensing, lab, radiology and infusion, with drug-interaction and dose-range checking built into every order.
- Orders and e-prescriptions with interaction checks
- Dose-range checking on every prescription
- Dispensing, lab, radiology and infusion connected

Pillar 03
Every service billed, every claim tracked.
GST-ready bills, package and tariff catalogues, TPA and PMJAY claims, UPI and card collection, and refund flows.
- GST-ready bills from package and tariff catalogues
- TPA and PMJAY claims
- UPI and card collection, with refund flows

Pillar 04
Built for the medical superintendent.
Live dashboards, KPIs, staff scheduling, inventory, audit and role-based access, in the same system your clinicians use.
- Live dashboards and KPIs
- Staff scheduling and inventory
- Audit and role-based access

How it works
From sign-up to first patient, step by step.

-
01
Discovery call
A 30-minute conversation about your hospital, current systems, specialties and pain points. No slideware.
-
02
Tenant provisioning
We provision your own cloud tenant, isolated from every other hospital, with its own subdomain and environment.
-
03
Migration & configuration
We import your master data, doctor list, tariff catalogue and historical patients, and check them with your team before go-live.
-
04
Go-live & training
Side-by-side training in your hospital, on your workflows, with our team on hand as you switch over.
Architecture
Modern stack. Not a 1995 client-server relic.
Cloud-native multi-tenant architecture, .NET 9 services, PostgreSQL and FHIR R4 over the wire. Designed to deploy quickly, scale as you grow, and keep a full audit trail.
Multi-tenant cloud
Tenant-per-hospital schema isolation. Hosted in India.
PostgreSQL 16
Row-level security, partition-by-tenant, point-in-time recovery, daily backups.
.NET 9 services
Modular vertical slices, OpenAPI specs and automated tests on core modules.
FHIR R4 wire
Patient, Observation, Encounter, MedicationRequest, ServiceRequest, Bundle.
Offline-first client
WPF desktop with delta-sync. Works on patchy 3G.
Audit trail everywhere
Append-only audit log on every clinical write. Designed for the DPDP Act 2023.
