Market size · estimate
How big this could get
A bottom-up estimate for Fleet Manager for Elderly Parents' Smart Devices: real customer counts × a realistic price. Not a forecast.
$1.8B a year
15M families · 25% of US family caregivers of an adult
$540M a year
4.5M families · online, US
$5.4M a year
45,000 families · 1% of the reachable segment in three years
What that means
45,000 families at $10/mo = $5.4M ARR
Medium confidenceHow we estimated this
- Base: 59,000,000 US family caregivers of an adult.
- Has the problem: 25% (assume a quarter help a parent with devices remotely).
- Revenue per familie: $120 per year ($10/mo).
- Reachable: 30% (online, US).
- Three-year capture: 1% of the reachable segment.
TAM = customers with the problem × revenue per customer. SAM = the part an early product can reach. SOM = a conservative three-year share of SAM. Bars use a log scale. Shares marked “assume” are our judgment, not measured.

Equity instead of cash is an application, not a checkout →Questions
Is this idea already taken?
People already use Each vendor's own app, Home Assistant. Those options do not do the job in the solution above. The idea is free to build. Nothing here is an exclusive claim.
How hard is a first version?
Hard. A tight MVP is about 5 weeks (5+ weeks), assuming the regulated or partner-gated parts are stubbed. The paid prompt turns that into tasks.
Who would pay, and how?
The audience is adult children and family caregivers. Charge a subscription, and test a price between $10 and $49 a month. Willingness to pay is one input to Hotness, not a promise that someone will buy.
Can I use the evidence?
Yes. Build the product. The thread title is a short excerpt with a link, not a quote we are putting in someone's mouth. Exact post dates and verbatim lines are added only after a manual check. Ideas are suggestions, not medical, legal, or financial advice.
