Meterbox

A $129 clamp that lets any repair company's AI agent hear your appliances failing.

Meterbox is a consumer-installed sensing device at the home electrical panel that reads current signatures per circuit and identifies which appliance is degrading, from a compressor drawing wrong to a dryer element cycling short.

$2,800 · 6 weeks · 30 prospects

For about $2,800 and 6 weeks, prove both sides at once: 30 homeowners in Phoenix and Dallas put down $50 refundable reservations on a $129 panel clamp, and 6 repair firms sign to pay $30 per verified-fault lead.

1Focus group: who and where

Homeowner in the Phoenix or Dallas-Fort Worth metro in a house 10 or more years old who paid an HVAC or appliance repair bill over $400 in the past 12 months and is bracing for the compressor to die in the next heat wave; on the platform side, the owner or operations manager of a local appliance repair or HVAC company with 3-20 techs

where to find 30 · Homeowners: Meta Ads geo-targeted to Phoenix and DFW homeowners aged 35-65, plus recruiting posts in r/hvacadvice, r/Phoenix and r/Dallas and on Nextdoor. Repair firms: ACCA Arizona and Texas chapter member lists and top-rated appliance repair companies on Google Maps in both metros

2Sell first, build later

To homeowners: a Meterbox unit from the first 500-unit production run at $129 with free alert service for year one, shipping March 2027. To repair firms: a signed referral agreement for verified fault leads in their zip codes at $30 per booked job, first leads flowing when 100 local units are installed

the ask · $129 per device with a $50 reservation; $30 per booked job for repair firms

a real yes · A real yes is $50 moved through Stripe or a signed referral agreement with per-job pricing. Email waitlist signups, 'cool gadget' comments on Reddit, and repair firms who want free leads 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. Repair-side referral fake door
$100 · 14 days
Call 15 repair company owners in Phoenix and DFW with a one-page offer: verified fault leads ('this address has a compressor drawing 18 percent over its start-current baseline') at $30 per booked job, no charge until the first booked job. Ask them to sign the one-page referral agreement on the call. This tests the revenue model before any hardware exists.
keep going if · 6 of 15 owners sign the referral agreement
2. $50 reservation landing page
$700 · 21 days
One-page site for the $129 Meterbox with a named ship date of March 2027 and a $50 refundable reservation via a Stripe Payment Link, the Model 3 playbook at consumer scale. Spend $600 on Meta Ads against Phoenix and DFW homeowners; creative leads with 'know your AC compressor is dying before August does.' Track cost per reservation, not clicks.
keep going if · 25 or more paid reservations at under $25 acquisition cost each
3. Concierge monitoring with off-the-shelf clamps
$1,800 · 30 days
Install Emporia Vue 3 energy monitors (an existing retail product) in 10 homes of reservation holders or Reddit recruits. The team reads the per-circuit data manually each week and texts human-written alerts such as 'your dryer element is short-cycling, expect failure within weeks.' This is the Wizard-of-Oz version of the whole product: real panels, real signatures, human doing the AI's job.
keep going if · 6 of 10 households act on an alert (book a repair or ask for a referral), and the team can correctly identify the failing appliance in at least 7 of 10 homes, testing the 60 percent disaggregation risk directly

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.

$50

per prospect, refundable

how · A $50 refundable reservation via a Stripe Payment Link on the landing page, confirmation email states unit price, ship date and refund terms; repair firms sign the one-page referral agreement with no money down since they pay per booked job set up: Stripe Payment Links ↗

what it reserves · A unit from the first 500-unit run, the $129 price locked, priority installation in the first two metros, and free alert service for the first year

refund · Refundable in one click from the confirmation email any time before the unit ships

target · 30 paid reservations within 21 days of ads going live

Go: build it if

30 or more reservations at under $25 CAC, 6 or more signed repair firms, and correct appliance identification in 7 of 10 concierge homes: order the first hardware run

Kill: stop if

Fewer than 10 reservations after the full $600 ad spend, fewer than 3 repair firms signed, or diagnosis right in fewer than 5 of 10 concierge homes, which is the stated risk that kills the platform side

The idea in full

What: Meterbox is a consumer-installed sensing device at the home electrical panel that reads current signatures per circuit and identifies which appliance is degrading, from a compressor drawing wrong to a dryer element cycling short. Homeowners buy it at retail and in home improvement channels for the alerts, and the device exposes a diagnostic API so repair firms, warranty providers, appliance OEMs and insurers can run their own agents against verified fault data instead of a phone description. Meterbox manufactures the hardware and takes a referral fee whenever an agent on the platform books a job.
Why now: Bernard (yc S26) is building AI employees that run home appliance repair companies and Kirana AI (2025) died trying to be an AI manager for physical stores without instrumentation, which is the same failure mode: agents in the physical trades have no sensor input. This cluster added 206 companies in 2026 with almost all of them software-only, so the ground-truth layer for home equipment is open.
Wedge: first customer and entry point: A three-person team sells through two regional home improvement chains and one home warranty provider in Texas and Arizona, where compressor failures are frequent and diagnosable.
Path to 100x: US home services and appliance repair is a $100B+ spend, and a device in millions of panels becomes the input layer every repair agent, warranty underwriter and OEM builds against. Each installed unit adds labelled failure signatures that make diagnosis better, which pulls more repair networks onto the platform and makes the device more valuable to the next buyer, so one library wins.
Ceiling: Appliance OEMs put connectivity in new units and utilities push their own panel sensors, leaving Meterbox a shrinking retrofit market and a hardware-margin business under $500M.
Closest real companies, as the generator saw them: Bernard automates the repair company's office and depends on whatever the customer says on the phone; Meterbox supplies the signal that makes those agents accurate and is neutral across every repair network. Marble and Axelrod run operations for restaurants and hotels rather than instrumenting consumer homes.
Main risk: Signature disaggregation is right only sixty percent of the time across mixed housing stock, so repair partners stop trusting the diagnosis and the platform side never forms.

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
3/5
A $129 panel clamp feeding every repair agent could own the input layer, but consumer retail hardware plus referral fees is thin economics.
Bootstrapper
1/5
Consumer hardware at $129 through home improvement retail means tooling, inventory and channel costs long before the first referral fee.
Operator
3/5
Homeowners do not feel appliance pain until failure, and the platform side only pays after millions of panels, so willingness to pay today is thin.
Technologist
4/5
Per-circuit load disaggregation at the panel is a hard signal problem, and each installed clamp adds labelled failure signatures competitors cannot buy.
Risk
3/5
Retail plus warranty channels spread risk, but early volume rests on two regional chains and one Texas warranty provider while OEMs embed connectivity.
trends
1/5
Current-signature disaggregation hardware predates 2023 by a decade, and nothing in the panel-clamp product depends on any shift the brief dates.
