Test it before you build it
$1,700 · 4 weeks · 30 prospects
For $1,700 and four weeks, prove homeowners will put $49 down on a $229 entry hub and that repair companies will sign to integrate, before any hardware is tooled.
Riskiest assumption · A homeowner who already owns a smart lock and a video doorbell will hand over money today for a second door device whose payoff arrives only two or three service visits a year.
1Focus group: who and where
A single-family homeowner, 35 to 65, in one metro area, who booked an HVAC or appliance repair in the last six months and burned a workday waiting out a four-hour arrival window; secondarily, owners of the HVAC and appliance repair companies that served them.
where to find 30 · Nextdoor neighborhoods and city homeowner Facebook groups in one metro (community); r/HomeImprovement and r/hvacadvice, where homeowners complain about arrival windows (channel); the local ACCA chapter meeting and the United Servicers Association member list for the repair-company side (association); Meta ads targeted at single-family homeowners in the same metro for volume.
2Sell first, build later
A door hub that verifies the technician's identity, grants time-boxed entry, records the visit and sends the repair company a machine-readable fault report before arrival: founding units at $179 instead of $229, installed free, shipping to the first 500 homes in spring 2027.
the ask · $49 refundable reservation now; $179 plus $9 per month billed at shipment
a real yes · A completed $49 card charge at checkout is a yes; email signups, survey interest, and repair-company compliments without a signed LOI are not.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Paid reservation pre-order test
$1,300 · 21 days
Stand up a pre-order page with the hub's renders, the $229 list price, a $179 founding price, and a $49 refundable reservation taken by card at checkout. Drive traffic with $1,000 of Meta and Nextdoor ads in one metro plus founder posts in r/HomeImprovement and local Facebook groups, and watch visitor-to-reservation rate daily.
keep going if · 20 paid $49 reservations from no more than 2,000 visitors
2. Repair company pull calls
$200 · 14 days
Run 12 calls with owners of HVAC and appliance repair companies found through the local ACCA chapter, the United Servicers Association list and r/HVAC. Show the fault report and verified-entry flow and ask whether they would integrate for free and prioritize hub homes; close with a one-page no-cost integration LOI naming a pilot ZIP code.
keep going if · 7 of 12 owners say hub homes would win them jobs and 4 sign the integration LOI
3. Distributor bundle meetings
$200 · 10 days
Take the reservation count and signed LOIs into three meetings with branch or territory managers at a regional HVAC distributor such as Johnstone Supply or Gemaire, and propose a 50-hub bundled pilot where dealers install the hub with new equipment.
keep going if · 1 branch agrees in writing to a 50-hub bundled pilot
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 refundable $49 reservation charged by card at checkout on the pre-order page, returning a numbered reservation by email. Chosen because a consumer can act in one sitting, and a card charge is the only thing that separates intent from politeness at this price point. set up: Stripe Checkout ↗
what it reserves · A numbered slot in the first 500-unit batch, the $179 founding price locked, and free installation
refund · Refundable in full any time before the hub ships, one click from any update email, money back within 5 business days.
target · 20 paid reservations from 2,000 or fewer visitors within 21 days
Go: build it if
20 or more paid $49 reservations at a blended acquisition cost under $50 each, at least 4 repair companies signed to integrate, and one distributor branch committed to a bundled pilot; then order the first tooling run.
Kill: stop if
Fewer than 8 reservations after 2,000 visitors and the full $1,000 ad spend, or fewer than 3 of 12 repair companies willing to sign an LOI; refund all reservations and stop.

outreach message
If you have burned a vacation day waiting out a four-hour repair window, this is for you. We are building a $229 door hub that verifies the technician's identity, grants entry for a set window, records the visit, and sends the repair company a diagnosis before anyone arrives. The first 500 homes get it for $179 with a $49 refundable reservation, installed free. I am the founder and will install the first units in this area myself. Want the link, or a 20-minute chat?

deposit terms
Your $49 reservation is fully refundable any time before your hub ships and locks the founding price of $179 instead of $229, installation included. Reservations are numbered and the first 500 hubs install in spring 2027, lowest numbers first. Every update email includes a one-click refund link; money is back on your card within 5 business days.

The idea in full
- What
- Homelatch sells homeowners a $229 door hub with a camera, a credential reader and a listening module that records appliance and HVAC sound signatures, plus a $9 monthly subscription. When a repair company's scheduling agent books a visit, the hub verifies the technician's identity, grants time-boxed entry, records the work, and hands over a machine-readable fault report so the visit starts with a diagnosis instead of a walkthrough. Revenue is hardware and subscription only; any service company can integrate for free, which is the point.
- Why now
- Bernard (yc S26) is building AI employees that run home appliance repair companies and Marble is doing the autonomous back-of-house for restaurants, so the dispatch side is being automated right now, while Kirana AI (AI manager for physical stores) went inactive in 2025 because a software agent with no sensors in the building had nothing true to act on.
- Wedge: first customer and entry point
- Sell through one regional HVAC and appliance distributor's dealer network as a bundled add-on at install: the dealer gets faster jobs, the homeowner gets keyless access, and the first 20,000 hubs are a single channel relationship.
- Path to 100x
- US home services is a $100B+ spend and the hub sits at the door of every visit in it; the network flips once enough homes carry a Homelatch that repair companies must integrate to win jobs, and once they integrate, the next homeowner has more reason to buy. Winner takes most because a home installs exactly one entry standard and service companies will support only the one with the largest installed base.
- Ceiling
- A lock and camera incumbent copies the technician-verification API in a firmware update and reaches thirty million homes overnight, leaving Homelatch as a niche accessory.
- Closest real companies, as the generator saw them
- Bernard automates the repair company's staff and Axelrod runs boutique hotels that run themselves; both operate on the business side of the door. Homelatch is owned by the homeowner and is deliberately neutral across every repair brand, which is what makes it the standard rather than one vendor's peripheral.
- Main risk
- Consumers already own smart locks and doorbells and will not buy a second device for a problem they only feel a few times a year.
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
Winner-takes-most at $100B+ home services is real, but a $229 second device for a rare problem faces brutal consumer hardware adoption.
Bootstrapper
2/5
A $229 hub against incumbent smart locks means inventory capital and consumer hardware churn on a problem felt twice a year.
Operator
1/5
The card admits homeowners already own locks and doorbells and feel the entry problem a few times a year.
Technologist
2/5
Acoustic signatures aside, a $229 hub is a technician-verification API that August or Ring absorbs in a firmware push to thirty million homes.
Risk
2/5
First 20,000 hubs ride a single regional distributor, and the card concedes a lock incumbent can ship technician verification by firmware to thirty million homes.
trends
2/5
Agent dispatchers like Bernard barely exist yet, so the hub arrives before its buyer; keyless entry hardware was equally buildable in 2023.
