Sentinel is a phone-first platform that screens for the three 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, and cervical cancer using only what a community health worker already carries. 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.
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.
