The Problem

Hospitals have data. AI companies have models.
Nothing moves.

Separated by compliance risk, legal liability, and a complete absence of trusted infrastructure to bridge the gap.

Hospitals
Data-rich. Legally exposed.
Indian hospitals sit on decades of irreplaceable clinical data. But sharing it, even with the best intentions, triggers DPDP liability, requires IRB approvals, and demands data processing agreements that take months to negotiate. By the time legal clears it, the AI company has moved on or the pilot window has closed.
AI & Healthtech Startups
Model-ready. Data-starved.
Indian healthtech startups building diagnostic AI, clinical NLP, or predictive models cannot access real Indian patient data at scale. They train on synthetic datasets, foreign cohorts, or small opportunistic pilots. Models built this way don't generalise and deployments fail. The gap between demo and clinical reality remains wide.
The missing piece has always been the infrastructure and not willingness. Hospitals want to contribute to AI in Healthcare. AI companies want Indian clinical data. What's missing is a trusted, compliant, auditable data bridge between them.
Sandhum is the bridge.
How It Works

A DEPA certified Confidential Clean Room

No raw data ever leaves the data provider institute custody.
No compromises on compliance, security, or auditability.

STEP 01
Deploy
Sandhum deploys your AI model or a federated training job into the Data Provider's secure, isolated environment. The institute reviews and approves what runs inside their walls.
Model goes in. Data stays put.
STEP 02
Compute
The model runs in a secure enclave. No data is copied, moved, or transmitted. Compute moves to where the data is and not the other way around.

Trusted Execution Environment.
STEP 03
Retrieve
Only inference results - model outputs, aggregated insights - leave the hospital environment. Raw data never does. Every step is logged, auditable, and DPDP-compliant.
Results out. Full audit trail included.

For AI & Healthtech Startups

You need real Indian clinical data. Sandhum is how you get it.

Building on synthetic data or foreign cohorts isn't enough. Indian disease patterns are different. Indian clinical contexts are different. Your models need to be built on Indian reality and not approximations of it.

Real
Indian clinical data - structured, consented, and accessible for the first time at scale.
Zero
DPDP liability on your side. The compliance risk stays where it belongs.
Faster Time to Data
Bypass months of hospital procurement and IRB cycles. Sandhum's framework means a signed agreement translates to running computation in weeks — not quarters.
No Compliance Overhead
Data never leaves the hospital wall. You carry no data custody. Your legal exposure stays minimal while your model trains on real patient cohorts.
Multi-Hospital Federated Training
Train across multiple hospital datasets without ever centralising patient records. Models improve across an entire network while each hospital retains full data sovereignty.
Deployment-Ready Audit Trail
Every computation is logged and consented from day one. When your model goes to clinical deployment, regulators and ethics boards get a clean, verifiable record of how it was built.

Why Trust Us

Built on India's proven DPI for trusted data exchange.

Sandhum's trust credentials are not marketing claims. They are verified, auditable, and embedded in the architecture of every engagement.

Verified
Samyog Empanelment
Sandhum, an offering of Navigrow Consulting, is an empanelled Trusted Service Provider on Samyog: India's DEPA-based governance platform for data collaboration. Empanelment requires rigorous technical and compliance review.
Framework
DEPA Architecture
Built on India's Data Empowerment and Protection Architecture. DEPA puts consent at the centre of every data transaction and every Sandhum engagement operates within this consent-first, audit-first framework from the first API call to the final result.
Compliant
DPDP Act 2023
The Digital Personal Data Protection Act sets strict requirements for processing health data. Sandhum's framework is designed so patient data never crosses an external boundary; which means the compliance obligations sit where they should: with the data custodian.
✓ Every computation is logged with a tamper-evident audit trail accessible to all parties.
✓ Patient consent is verified and recorded before any model runs against a dataset.
✓ Hospitals retain the right to inspect, pause, or terminate any engagement at any time.
✓ No raw patient records are ever transmitted, stored, or accessible outside the hospital environment.
