Market
A massive, urgent demographic shift
America's seniors are staying independent longer — driving themselves, living at home, and relying on family caregivers for remote oversight. Hearthguard sits at the intersection of automotive telematics, digital health, and family safety.
56M+
Americans aged 65 and older — the fastest-growing consumer segment in the U.S.
10,000
Baby boomers turn 65 every day, expanding the addressable caregiver market continuously.
53M
Family caregivers providing unpaid care — our primary buyer and champion inside each household.
$600B+
U.S. care economy spanning home care, health tech, and safety monitoring spend.
Competitive moat
Integrations competitors cannot copy overnight
Hearthguard is not a generic GPS tracker. Deep OEM, smart-home, and clinical partnerships create switching costs and defensible data fusion across the road and the residence.
Smart-home monitoring & orchestration
Premium OAuth for Ring, Samsung SmartThings (multi-location), Govee, Philips Hue, and Google Nest SDM. Safety automation flows turn SOS and fall events into porch-light pulses and lock commands in seconds. Advanced Options lets caregivers chain cross-vendor actions on home events, schedules, or manual run — a workflow layer competitors bolt on with IFTTT.
Epic SMART on FHIR
Production patient portal OAuth brings medications, conditions, and vitals into the caregiver dashboard — clinical context no standalone tracker offers.
SAR tooling
Location Detective exports interactive Leaflet SAR briefings, NIMS ICS forms, GPX tracks, vehicle containment when telemetry is offline, home-activity timeline fusion, and 48-hour responder PIN handoffs — plus a public SAR field guide at /sar for search teams.
Household platform
Multi-caregiver roles, tiered billing, wellness check-ins, NWS weather alerts, audit logs, and elder iPhone companion create a sticky household graph with expanding ARPU over time.
Business model
Recurring household subscriptions
Three Stripe-backed tiers from $9.99 to $29.99 per month. Revenue scales with caregiver households, not per-seat enterprise contracts.
| Tier | Price | Key unlock |
|---|---|---|
| Essential | $9.99 / mo | Live location, SOS, push alerts, 1 caregiver |
| Guardian | $19.99 / mo | Geofencing, Tesla commands, 3 caregivers, SMS & email |
| Premium | $29.99 / mo | Home integrations (Ring, SmartThings, Govee, Hue, Nest), safety automation & orchestration, behavior & device alerts, selective pause, NWS weather, wellness check-ins, audit log |
Blended ARPU assumes a majority Guardian mix with Essential land-and-expand and Premium upsell for high-acuity households. Gross margin improves as Tesla API costs amortize across telemetry subscribers.

Go-to-market
Land through caregivers who already own Teslas
Bottom-up adoption: one worried adult child subscribes, invites siblings, and upgrades as safety needs escalate.
Tesla owner communities
Forum partnerships, referral loops, and Fleet app store discovery reach high-intent buyers already driving the vehicle we monitor natively.
Caregiver content & SEO
Search-driven guides on dementia wandering, seniors who drive, and remote safety monitoring convert anxious researchers into subscribers.
Smart-home upsell
Families already own Ring doorbells and Samsung appliances. Premium home monitoring converts existing hardware into caregiver alerts without new wearables — a natural upgrade from Guardian.
Clinical & SAR adjacency
Epic FHIR credibility with geriatric practices; ICS exports and responder PINs build trust with search-and-rescue networks and elder law firms.
