A navigation intelligence layer - Oncology
Know where the case stands. Know who it should reach.
The case is currently at Summary - Next stop - Review
What it is
A GPS in a car tells you where you are and how to reach where you need to go. Cancer Care GPS does the same for an oncology case — it tells the system where the case stands, and routes it to the specialist who should reach it next. The value is not summarisation. It is orientation.
The value is not summarisation. It is orientation.
— A founding principle of Cancer Care GPS
The architecture
Each layer does one thing, and does it well. Each is independently useful. Together, they compound — and that compounding is where the real intelligence lives.
The layer that reads the case. Fragmented patient records — in any format — become a structured clinical view. Every value is traceable to its source document. A specialist can read the case in four minutes instead of two hours.
Medical document parsing - 200+ structured data points - 70+ biomarkers - 5 guideline systems cross-checked - FHIR R4 / LOINC interoperable - Human clinician verification on every case.
The layer that routes the case. Each second opinion reaches the specialist whose actual sub-specialty fits — not by geography, not by who is available, but by who is right. The patient sees the match score and chooses.
Multi-factor routing model - disease management group - stage - biomarker profile - treatment history - complexity - sub-specialty focus - case-volume calibration - industry-first match-score transparency.
The layer behind both. Every case L1 structures is scored for concordance against National Cancer Grid (India's Tata Memorial-led standard), ICMR, and NCCN guidelines. The patient sees whether their current treatment plan aligns with what India's top cancer centres recommend for their exact profile. Output is FHIR-interoperable - any hospital EMR or tumour board system can consume it directly.
Guideline concordance scoring (NCG, ICMR, NCCN) - NCI PDQ + MedlinePlus + PMC knowledge base in pgvector - FHIR R4 output - DPDPA-compliant.
L1 reads. L2 routes. L3 knows.
The Sages behind it
A small founding team — on purpose. Each of us is responsible for a part of the platform that touches the patient directly.

Founder & CEO
MD Radiodiagnosis (TMH) - CPHM (ISB) - EPHM (IIM)
A radiologist by training, Pritesh leads the clinical and product vision at The Brown Sage. He shapes how the platform reads, structures, and routes every case — and personally runs the founding panel of TMH-alumni oncologists who provide the second opinions.

Co-Founder & CTO
MSc Big Data & AI - Berlin University of Technology
Kaushal leads technology and AI at The Brown Sage. He architects the platform's core systems and data pipelines - the intelligent extraction pipeline, RAG-based guideline validation, case fusion algorithm, and the clinical intelligence engine that turns fragmented records into a structured, doctor-ready view.

Co-Founder & COO - Clinical & Network
NIPER - Eli Lilly - Eris Lifesciences
Gaurav leads clinical partnerships and the specialist network. He works directly with our founding oncologists to ensure rigorous review standards, fair workflow, and a quality of opinion that the patient — and any treating clinician — can rely on.

Co-Founder & COO - Platform & Growth
Sushen - GMP
Sushil leads patient experience, regulatory compliance, and the international corridors. He brings deep experience in cross-border regulatory frameworks and ensures the platform meets the standards every region demands.
How it began
As a radiologist at TMH, Pritesh sat at the intake point of every cancer case — and saw the fragmentation from the inside. Records that didn't speak to each other. Biomarkers buried inside long PDFs. Treatment chronologies that lived only in the patient's memory. The gap wasn't downstream. It started at intake. He stepped out of clinical practice, studied healthcare strategy at ISB and IIM, and came back with a team to build for what he had seen.
Our principles
Four things every patient, every specialist, every partner can count on — regardless of where The Brown Sage grows from here.
Principle 01
We earn from the patient's fee, not from where the patient goes next. We do not take commissions from any hospital, clinic, or pharmacy for referrals. Ever. This is the principle that organises every other decision at The Brown Sage.
Principle 02
Technology helps us organise the information. But a clinician verifies every detail, and a board-certified specialist writes every opinion. There are no shortcuts on the case itself.
Principle 03
Every part of the platform is built around India's Digital Personal Data Protection Act, the NMC Telemedicine Practice Guidelines, and the data-protection standards of every region we serve. No shortcuts.
Principle 04
Every record you upload, every opinion you receive, lives in your account for as long as you want it there. You can download it, share it, carry it to any hospital. We are a stop on the journey, not a destination.
