One shared schedule for every UK school pickup — siblings, swap-mums, grandparents — with auto-fallback when Plan A fails.

What we ship

**Core features (MVP)**

• School-term PDF calendar import by UK postcode (LLM parses INSET days, half-terms, end-of-day times)
• Pickup-chain builder: child × time-window × named adult × backup
• One-tap "I've collected — at home" confirmation via SMS, visible to all chain adults
• Auto-fallback: if Granny didn't confirm by 15:35 → call backup + push notification to parent
• Swap-Mum tracker: log "I picked up your Olivia Tue" with reciprocity counter

**Primary user flow**

1. Sign up → enter postcode → upload school PDF calendar(s)

2. Add children, schools, swap-mums and childminders with pre-authorised flag

3. Set daily template: who picks up, when, backup

4. Trigger: after 14 days of use → Premium upsell (£4.99/mo) for unlimited backup pool

**What it looks like**

• **Landing page**: "Stop the 3pm panic. One shared schedule for every UK school pickup." + chain screenshot + CTA "Try free for 1 child"
• **Main app screen**: vertical day timeline per child, colour-coded "scheduled / in-transit / home"
• **Output / notification**: SMS to grandparent: "Granny — Tom's pickup 15:30 at St. Mary's, Mum is in clinic till 17:00. Reply DONE when home."

**MVP build plan (12 days)**

• Day 1-3: Postgres schema, FastAPI auth, Twilio integration
• Day 4-7: school-PDF parser (Claude API), pickup-chain UI, calendar export
• Day 8-10: Stripe subscriptions, fallback engine, SMS templates
• Day 11-12: landing, deploy to CF Pages, Mumsnet beta launch

Reasoning

Cluster of 4 SIGs covering the same operational primitive — UK-specific pickup chain coordination with named back-ups. Brave-search confirms zero direct competitors (only minicab services and childcare directories). UK-specific structural pain: staggered school finish times, INSET differences between academy trusts, wraparound care at £22-46/day making peer-swap economically critical. Generic US calendar tools (Cozi, FamilyWall) don't model the state-machine of "scheduled → in-transit → home" or pre-authorised backup adults. White space.

Quick competitive read

5 incumbents profiled (CMP-IDEA-064-*). All occupy adjacent or complementary planes — none address parent↔grandparent↔swap-mum↔childminder pickup-chain coordination on the UK school-gate side.

• **IRIS ParentMail** (CMP-IDEA-064-parentmail): UK incumbent in school→parent broadcast (since 2003; IRIS Software Group). Sold to schools per-pupil; parent app is free. Direction of data flow is school→parent, not parent↔parent. Complementary infrastructure (we ingest the term-PDF they distribute), not a competitor.
• **Tes Class Charts** (CMP-IDEA-064-class-charts): UK behaviour-management dashboard with school-paid licence + free parent app. Detention-API is the only operational overlap and is best treated as an integration input (detention shifts pickup time → we re-route the chain). School-managed list, not parent-managed network.
• **ClassDojo** (CMP-IDEA-064-classdojo): Global K-8 classroom comms; ClassDojo Plus at $7.99/mo / $59.99/yr is the most useful parent-WTP anchor in the cluster (ours sits below). Lower UK primary penetration than ParentMail/Class Charts, and inside-classroom problem space.
• **Cozi Family Organizer** (CMP-IDEA-064-cozi): Generic US family calendar, $39/yr Gold = canonical category anchor. No UK-school-PDF parsing, no INSET awareness, no state machine, no auto-fallback. May-2024 free-tier downgrade has created an active churn window.
• **Pikmykid** (CMP-IDEA-064-pikmykid): US K-12 school-paid dismissal-safety platform ($3,750/yr per school location, 5,000+ US schools). Parallel market plane — school-budget B2B vs our parent-WTP B2C; carline (drive-up) UX assumption, not UK walked-pickup; no UK launch in roadmap.

**Market density: medium** (5 plausible incumbents, but each in an adjacent plane — none directly address the UK pickup-chain mesh problem).

**White-space observation**: parent-side, peer-mesh, post-school-bell coordination with state-machine fallback and named back-up SMS authorisation is **structurally unaddressed** by both UK school-comms incumbents (ParentMail, Class Charts) and US/global family organisers (Cozi, ClassDojo, Pikmykid). The competitive read for `competitive_pressure: 8` holds — it's a defensible niche between three saturated adjacent categories.

**Pricing recommendation update**: ship £4.99/mo + £29-£49/yr annual to land at-or-below Cozi Gold ($39/yr ≈ £31/yr) and ClassDojo Plus annual ($59.99/yr ≈ £47/yr).

Initial pricing hypothesis

Free tier: 1 child + 2 named adults. Premium **£4.99/mo/family**: unlimited children/adults + backup-pool + childcare-voucher tracking + LEA evidence export.

Distribution hypothesis

Organic Mumsnet/Netmums posts in the existing pickup-clash threads (replicate the SchoolAlerts.ie parent-built-tool playbook), TikTok #schoolrun reels, postcode-bound Facebook ads to mums-of-2+-at-different-schools in catchment-overlap zones (Reading, Bristol, Manchester).
