Sentinel is a phone-first platform that screens for five of the deadliest cancers, then does what most tools don't — it makes sure the people it flags actually reach a clinician. Built for community health workers, in the places where late detection kills.
A screening result that says "you should see a doctor" saves no one if the visit never happens. Distance, cost, fear, and a lost paper slip break the path between being flagged and being treated. Sentinel exists to close that break.
Sentinel screens for lung, breast, cervical, skin, and prostate cancer using only what a community health worker already carries — including the skin cancers that strike hardest in darker skin, and prostate cancer, the commonest cancer in Nigerian men. Every flagged case is carried forward — explained, tracked, and connected to care — instead of handed off and forgotten.
A short history, a method-specific signal — a cervical image, a voice recording, a guided breast exam — and the worker's own structured observation. When the number and the observation disagree, Sentinel escalates to the safer action.
The Interception Index is a transparent, auditable triage score — never a diagnosis, never invented by a language model. AI explains it in the patient's language and cites the WHO, USPSTF, and peer-reviewed evidence behind every call.
Patients and health workers can ask what the result means and what happens next. It reassures without ever claiming a diagnosis — and routes questions that need a doctor to a real one.
Every flagged patient becomes a tracked referral with a lifecycle and a due date. Overdue cases resurface for gentle re-contact. The system encourages and tracks relentlessly — it never coerces.
When distance is the barrier, a case routes to a remote clinician — async where signal is thin, live video where it isn't. The specialist's decision flows back and closes the loop.
Every result carries a built-in Red Team review that names what could be wrong, and separates the screening method's published accuracy from the tool's own status. Honesty is the design, not the disclaimer.
Sentinel puts AI where it genuinely helps: turning a cold triage score into a warm, plain-language explanation, reasoning against real clinical evidence, and stress-testing its own conclusions. And it holds firm boundaries — because for a health tool, an overclaim is not a marketing problem, it's a safety one.
Sentinel produces one standard referral packet and routes it by region: an established telehealth network in the US, our own clinicians in Nigeria — with data sovereignty built in from the first record.
Flagged cases route into an established provider network for scheduling and specialist consults.
Cases route to our own clinicians over the channels they already use, with live video where signal allows.
Every test you have ever taken asked how far you are from average, right now — a snapshot, measured with a stranger's yardstick. We are building toward a different question: how far are you from yourself, and in which direction are you moving? Cancer does not begin on the day it is found. It begins as drift, and drift is visible long before disease — but only to something that has been watching.
The specific methods, measurements, models and sequence that carry us from here to there are deliberately not described on this page. What you can see is the destination — and exactly where we stand on the road to it.
Sentinel is looking for clinical, funding, and health-system partners to move from validated prototype to lives changed. If that's you, let's talk.
