Carepuck
A $99 puck that watches a parent's home, with an app store for care.
Carepuck is a plug-in device with millimeter-wave motion sensing and on-device audio that adult children buy online and mail to a parent living alone; it learns the household routine and texts the family when something breaks the pattern, with no cameras and no medical claims.

Test it before you build it
$1,250 · 3 weeks · 30 prospects
For $1,250 and 3 weeks, learn whether adult children will pre-pay $49 plus a subscription commitment for camera-free monitoring of a parent's home.
Riskiest assumption · An adult child aged 45-60 with a parent living alone in another state will move money now, a $49 pre-order plus a monthly commitment, for camera-free presence alerts, instead of treating the daily phone call as good enough.
1Focus group: who and where
A 45-60 year old adult child with a parent 75 or older living alone in another state, within 90 days of a scare: a day of unanswered calls, a fall found late, or a parent who refused a camera or a pendant.
where to find 30 · r/AgingParents and the AgingCare.com caregiver forum (communities where the scare gets posted the day it happens), Facebook groups for people caring for aging parents, Meta paid social targeted at US adults 45-60 with caregiving interests (channel), and caregiver support groups run by local Area Agencies on Aging (venue).
2Sell first, build later
The Carepuck first batch: a plug-in presence puck shipped to the parent's home in January 2027, four-minute setup with no installer, and a text to your phone when the household routine breaks - no camera, nothing worn, nothing to charge.
the ask · $99 for the device plus $15 a month; pre-order now for $49 refundable, founding families lock $12 a month for the first year.
a real yes · A real yes is a $49 card charge, and a stronger yes adds the $36 prepaid first quarter. Waitlist emails, upvotes, and 'my siblings would split this' are not yeses.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Paid social pre-order test
$800 · 14 days
Stand up a landing page with the puck render, the $99 plus $15 a month pricing, a January 2027 ship date and a $49 refundable pre-order checkout. Run $700 of Meta ads at US adults 45-60 with caregiving and aging-parent interests, split-testing two headlines, one founder watching conversion daily.
keep going if · 12 or more paid pre-orders at a cost per pre-order under $60
2. Prepaid founding plan upsell
$50 · 7 days
Email every pre-orderer within 24 hours with the founding offer: prepay the first quarter, $36 at a locked $12 monthly rate, to join the first-500 batch and the design feedback group. One founder sends each email personally and logs replies.
keep going if · 40% of pre-orderers prepay the $36 quarter
3. Scare-story caregiver interviews
$400 · 12 days
Recruit 15 adult children from r/AgingParents and the AgingCare.com forum by messaging people who posted about a scare in the last 90 days, offering a $25 gift card for a 20-minute call. Map what they do today (daily calls, cameras the parent refused, pendants abandoned in a drawer), then show the priced page and ask them to pre-order on the call.
keep going if · 10 of 15 describe a concrete scare in the last 90 days and 5 of 15 pre-order live on the call
4Collect a deposit up front
Tesla took $1,000 refundable reservations for the Model 3 and $100 for the Cybertruck before building either: the deposit is the measurement, not the revenue.
$49
per prospect, refundable
how · A $49 refundable pre-order charged to a card at checkout; consumers will pre-order hardware with a firm date but will not sign letters, so a card charge is the honest instrument for this buyer, with the prepaid $36 first quarter as the second, stronger commitment. set up: Stripe Checkout ↗
what it reserves · A unit in the first 500-unit batch shipping January 2027 and the $12-a-month founding rate locked for 12 months.
refund · One-click full refund any time before shipment, and an automatic refund if the January 2027 date slips.
target · 25 pre-orders within 21 days, at least 10 of them with the prepaid quarter
before taking money · Keep every ad and page free of medical, fall-detection or emergency-response claims to stay outside FDA device territory, and get the parent's written consent before any in-home audio pilot, since many states require all-party consent to record.
Go: build it if
25 or more paid pre-orders at a cost per pre-order of $60 or less, with at least 40% adding the $36 prepaid quarter: order the first component run.
Kill: stop if
Fewer than 8 pre-orders from 2,000+ landing visits, a cost per pre-order above $150, or under 15% taking the subscription add-on - the vitamin objection stands.

outreach message
You posted about your parent not answering the phone for a day. I am building Carepuck: a $99 plug-in that learns the household routine and texts you when it breaks - no camera, nothing your parent wears or has to charge, $15 a month. It does not exist yet, and I am doing 15 calls with people in exactly your spot before we build it. Could I get 20 minutes this week? I will send a $25 gift card for your time.

deposit terms
Your $49 pre-order reserves one Carepuck from the first batch of 500, shipping January 2027, and locks the $12-a-month founding rate for your first year. It is fully refundable with one click any time before your puck ships, and refunded automatically if we miss January 2027. The $49 is credited against the $99 device price.

The idea in full
- What
- Carepuck is a plug-in device with millimeter-wave motion sensing and on-device audio that adult children buy online and mail to a parent living alone; it learns the household routine and texts the family when something breaks the pattern, with no cameras and no medical claims. The $99 device plus $15 a month is bought self-serve with a card and set up in four minutes. A published skills SDK lets pharmacies, meal delivery services and family-care apps run on the puck's presence signal and pay revenue share, so Carepuck becomes the sensor other consumer services build on.
- Why now
- Care Mojo, in the Techstars 2026 class, is the only always-on eldercare companion among the 107 companies tracked in the last two years, and it is software-only; there is no hardware presence layer in the set, and the radar shows no crowded pitch phrase repeating across four or more recent companies in this cluster.
- Wedge: first customer and entry point
- Sell direct to the adult child, not the parent, through paid social aimed at 45 to 60 year olds with a parent living alone in another US state, one SKU, no install visit.
- Path to 100x
- US consumer spending on aging-in-place support is well past $100B and largely unmediated by software; a cheap device that families already have plugged in becomes the distribution point every care service wants to reach, and the installed base is the moat. Winner-takes-most comes from the skills ecosystem: the puck with the most homes gets the most third party services, which sells more pucks.
- Ceiling
- Consumer hardware churn and returns keep net revenue retention under 100%, and it settles as a $200M device brand rather than a platform.
- Closest real companies, as the generator saw them
- Care Mojo is an always-on AI safety companion for older adults at home delivered as software; Carepuck ships the sensing hardware underneath that category and opens it to third party skills rather than owning the companion experience.
- Main risk
- False alerts at 2am train families to ignore the product, and the subscription churns out inside six months.
Five judges
Each judge scores every idea in the catalog with a named rubric; the venture judge decides whether a card is shown at all (4-5 is venture-grade).
Venture investor
4/5
$99 self-serve hardware plus $15 monthly sold direct to adult children reaches revenue within a year and the skills SDK makes installed base the moat.
Bootstrapper
2/5
$99 hardware sold through paid social to adult children means CAC, returns and the card's own sub-six-month churn admission.
Operator
2/5
$15 a month from an adult child for peace of mind is a vitamin, and 2am false alerts churn it out before the skills ecosystem exists.
Technologist
3/5
Millimeter-wave plus on-device audio at $99 is credible engineering, but the modules are off the shelf and the routine model is shallower than three-year R&D.
Risk
3/5
Direct self-serve sales avoid a gatekeeper, but paid social to 45-60 year olds is one acquisition channel and 2am false alerts drive churn.
trends
3/5
AI for the Aging Population is a current YC RFS, but a $99 mmWave puck was buildable in 2023 so timing is theme fit, not necessity.
