What we ship

**Core features (MVP)**

• On-demand 4-hour booking: "need caregiver in 1 hour, Sukhumvit area, child age 6, mild fever" → AI matches a verified caregiver within 1-hour radius, prioritizing those who've worked with this family before
• Verified caregiver pool: first-aid certified (Thai CPR courses), background + reference checks, 2-year minimum experience; monthly retainer paid to caregivers ensures dispatchability
• "House Playbook" — pre-uploaded by family: routines, allergies, medications, dietary preferences, emergency contacts, school authorization PDFs; AI generates a 3-minute Thai briefing for the caregiver when booking confirmed
• Health log: caregiver updates every 30 min (temperature, intake, sleep, symptoms); real-time push to parent
• Employer template: AI generates a Thai email/LINE message to the employer per TH labor law (sick leave, half-day, formal vs informal); reduces mom's anxiety about "losing my job"
• Subscription 299 THB/mo: priority dispatch + 2 free hours/mo + locked rate (no surge); on-demand without subscription 690 THB / 4 hours

**Primary user flow**

1. Thai landing, hero "ลูกป่วยกะทันหัน — เรามาเลย ภายใน 1 ชม." — sign up via LINE Login

2. One-time setup: "House Playbook" — child (name, age, allergies, medications), school, emergency contacts

3. Subscription (optional) or single booking flow → match → confirm in LINE bot

4. Caregiver arrives in 30-90 min; parent gets live LINE updates

5. After each booking — rating + tip; 2 repeat bookings lock that caregiver into the family's "favourites" pool

**What it looks like**

• **Landing**: hero "10 โมง ครูโทร 'มารับลูกด่วน' ทำยังไง?", 30-sec video case (mom in meeting → opens app → caregiver at door in 60 min); CTA "สมัครฟรี 30 วัน"
• **Main screen**: prominent SOS "📞 จ้างคนดูแลลูกตอนนี้" (red button) + favourite-caregivers list + current booking timeline
• **Caregiver app**: incoming booking with family playbook + map + ETA; "I'm en route" / "I'm here" buttons
• **Output**: real-time LINE updates "🌡️ 12:30 Pao 38.4 / paracetamol 5ml taken / sleeping now" + end-of-day PDF report

**MVP build plan (14 days)**

• Day 1-3: backend User+Family+Child+Caregiver+Booking+Match+HealthLog; LINE Login

Reasoning

SIG-sick-child-no-coverage is the sharpest RECURRING pain in the category, with a direct quote from a single mom about family pressure to quit. UNDP and FamBear/Kiidu confirm it: agency-style nanny (24-72h lead, full-day minimum) doesn't fit this scenario. Every mom hits this 8-12 times a year — known statistical load. **Nobody** ships on-demand sick-day childcare with 1-hour radius and a subscription-retained pool in Thailand.

Stack-fit: marketplace + matching engine — standard pattern. 14 days — longer because of supply-side onboarding (manually verified caregivers), but that guarantees quality at MVP. Important: this is NOT a medical service (no diagnosis, no medication dispensing) — we're a coordination layer; caregiver follows family doctor / aspirin guidance. D-005 should not trigger (we are not a bank, not an EMR, not licensed medical).

Strong moat: each repeat booking improves caregiver-family fit (AI learns preferences) — switching cost rises. Subscription retainer to caregivers (paying ~1500 THB/mo seasonal retainer) ensures supply.

Special angle: employer-letter AI generation removes a mom's anxiety block ("scared to tell boss the kid is sick") and routes her to an actionable workflow.

Quick competitive read

• **FamBear / Kiidu / BKK Nanny / Care Nest** — agency-style, 24-72h lead, full-day minimum; no fit for sick-day.
• **Care.com / Helpling TH** — generic gig marketplace, no medical context, no on-demand.
• **WhatsApp/LINE community helper-pools** — informal, no verification, no matching.
• **TH government childcare aid** — government child-health centers (Khlong Toei etc.), walk-in healthcare only, not childcare.
• **Helpr (US)** — direct analog, on-demand backup childcare; doesn't operate in TH, uses Stripe.
• **White space**: TH on-demand sick-day childcare with 1-hour radius + verified pool. Competitive pressure 9/10.

Initial pricing hypothesis

Free tier — registration + House Playbook setup; 299 THB/mo Subscription (priority dispatch + 2 free hours/mo + locked rate); 690 THB / 4-hour booking on-demand without subscription (690 vs 1500-2500 at full-day agencies); Premium 799 THB/mo with 4 free hours and same-caregiver guarantee. Anchor: mom loses 1500-3000 THB on a missed work day; 690 THB for coverage = direct ROI on the first incident.

Distribution hypothesis

1. Facebook BKK Working Moms (60K), Single Mother Thailand, Khon Kaen Mums — case-study posts with anonymized real-mom quotes

2. Pantip Family + Single-mom threads — "build-in-public" documentation

3. TH Twitter — short reels "10 โมง โรคโยน — 11 โมง พี่เลี้ยงมาเลย"

4. Partnerships with TH school nurses (Anuban + Pratom) — leaflets for parents

5. Corp partnership with co-working spaces (HUBBA, JustCo) — sick-day childcare as employee benefit
