Continuous Cancer Interception

Finding cancer early is only half the job. Reaching care is the other half.

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.

cancer deaths a year — the burden falls hardest where screening is scarcest
higher breast cancer mortality in low-resource settings — driven by late presentation, not biology

The problem no screening tool solves

Detection without follow-through is where people die.

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 is the only step that treats "reach care" as its job, not the patient's problem.
How it works

One phone, the full arc — from screening to a seat in front of a clinician.

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.

Screen & measure

Quantitative and qualitative, together

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.

Interpret with evidence

A clear number, grounded in guidelines

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.

Answer their questions

A conversation, not a verdict

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.

Refer & follow through

Tracked until care actually happens

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.

Connect to a specialist

Telehealth as the first line of defense

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.

Built to withstand scrutiny

An adversary in the room

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.

The AI, with a spine

Artificial intelligence that reasons and explains — but never pretends.

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.

STATUS: investigational prototype.
Sentinel has no established performance of its own until prospective clinical validation. Method accuracy ≠ tool accuracy. Not a diagnosis. Not yet cleared.
Screening, never diagnosisIt flags who needs a closer look — it never tells anyone they have cancer.
The number is auditableThe Interception Index comes from a transparent model — not from a language model.
Grounded in evidenceEvery clinical claim cites the WHO, USPSTF, or peer-reviewed literature — no invented facts.
Its own adversaryA built-in Red Team attacks every result so a stakeholder never has to find the flaw first.
Equity by designBuilt and validated across ancestry and setting — not tuned to one population and hoped onto others.
One platform, two markets

The same front door — routed to the care network that fits each place.

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.

United States

CareClix telehealth network

Flagged cases route into an established provider network for scheduling and specialist consults.

  • Integration-ready for the CareClix API
  • Data resident in North America (nam5)
  • Live and asynchronous consult paths
Nigeria

Our doctors, reachable anywhere

Cases route to our own clinicians over the channels they already use, with live video where signal allows.

  • Async review link plus Daily video consults
  • Data sovereignty: migrating to MTN Cloud
  • Works offline; syncs when signal returns

Let's close the gap between flagged and treated.

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.
