Hearthline — 90-Day MVP Roadmap

Success is not “AI platform.” Success is: a Portmore household photographs real clinic paper, shares a radar into WhatsApp, and nobody was asked for a card.

Team (small, Jamaica-present)

• 1 product/design (must be on-island part of each week)
• 1 full-stack
• 1 ML/extract (can be remote; tested on Jamaican paper)
• 1 community (Kingston + one rural parish)
• Legal: DPA notice, company registration, 876 number

Milestones

Days 1–21 — Trust before pixels

• Register the Jamaican entity; print the red-flag card.
• Collect 40 real (consented) anonymised discharge/script photos from two parishes.
• PWA shell: shutter, trust copy, 876 footer.
• Metric: 10 strangers will photograph a *dummy* paper without asking “ah weh unuh tek mi card number?”

Days 22–50 — Extract + radar

• Confirm/correct loop that is faster than typing.
• Polar radar; share PNG; revoke.
• Offline last-radar.
• Metric: on a 20-document holdout, ≥70% of high-blast-radius intervals recoverable with ≤2 corrections.

Days 51–75 — Parish desks

• Two walk-in partners (pharmacy or credit union) in Kingston Metro and one other parish.
• Diaspora view link tested from a US number.
• Metric: 30 live households, 0 payment-phishing reports.

Days 76–90 — Quiet launch

• Circle billing only for overseas volunteers, after free view.
• Harbor mode.
• Kill criterion: if people think we take remittance, we stop marketing and rewrite every screen.

Resource requirements

• Phones: mid-range Android (Redmi/Tecno class), not a demo iPhone-only.
• Data: Digicel + FLOW SIMs for field tests.
• Budget honesty: the expensive part is being present, not GPUs.

Success metrics (90 days)

Out of scope (90 days)

Helper marketplace, hospital FHIR, iOS-only polish, tokenisation of medical records.
