Test it before you build it

$800 · 4 weeks · 20 prospects

For $800 in 4 weeks, prove that independent auto shop owners in one metro will prepay $199 for an after-hours answering line and, the real question, hand refused jobs to a competing shop nearby for a 10% referral fee.

Riskiest assumption · An independent auto shop owner will send a paying job to a competing shop two streets over in exchange for a 10% referral fee, and accept jobs back on the same terms, rather than treat the neighbor as a competitor and switch passing off.

1Focus group: who and where

Owner-operators of independent auto repair shops with 2-8 bays in one metro, who personally return missed-call voicemails at 9pm and turned away jobs last week because the wrong make came in or no lift was free

where to find 20 · The Auto Shop Owners Group (ASOG) on Facebook, a Google Maps and Yelp pull of every independent shop in one metro (filtering out dealer service and national chains, which yields 100+ owners with phone numbers in an afternoon), and the local ASA (Automotive Service Association) chapter meeting; the Ratchet+Wrench Management Conference works as a backstop if the test runs during it

2Sell first, build later

Live within one day on your existing number via call forwarding: after-hours answering, booking straight into your current calendar, job deposits collected into your own Stripe account, and membership in the metro passing network that sends you the jobs nearby shops cannot take

the ask · $199 per month per location prepaid, plus 10% of the invoice on jobs passed to you, founding rate locked for 12 months

a real yes · A real yes is a prepaid first month and a signed reciprocal passing agreement; 'sounds great, come back when more shops join,' free-trial requests, and shops that sign to receive jobs but refuse to send them are noes

3Small experiments

The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.

1. Will shops pass jobs
$250 · 7 days
Visit or call 20 shop owners from the Google Maps list and ASOG. Ask each to name the jobs they turned away last month and why, then put the uncomfortable offer on the table: a written reciprocal agreement to send those jobs to a named member shop nearby for a 10% referral fee, and to receive jobs back on the same terms. The founder does every conversation personally and writes down each refusal reason verbatim.
keep going if · 10 of 20 owners sign the one-page reciprocal passing agreement naming at least one shop they will send to
2. Two-week live overflow line
$400 · 14 days
For the 6 most clustered signed shops, set up after-hours call forwarding to a Twilio number running an off-the-shelf voice agent configured with each shop's services, hours and calendar, with the founder monitoring transcripts nightly. When a call is out of scope for the receiving shop, the founder manually re-routes it to the agreed member shop the next morning and logs whether it is accepted.
keep going if · 25+ after-hours calls answered, 8+ jobs booked into calendars, and 5+ passed jobs accepted by the receiving shop
3. Prepaid founding members
$150 · 10 days
At the end of the live test, offer all 20 shops (including the 14 who watched from outside) founding membership: $199 first month prepaid on the spot, rate locked for 12 months, live within 14 days. Present each shop its own numbers from the test - calls answered, jobs booked, jobs received from neighbors - as the close.
keep going if · 8 of 20 shops prepay $199

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.

$199

per prospect, refundable

how · First month prepaid at $199, charged to the owner's card at the shop during the closing visit, attached to the signed reciprocal passing agreement; prepayment is the standard motion for shop owners already paying answering services monthly, so a card charge on the spot is the honest instrument

what it reserves · A founding slot in the metro's passing network, the $199 rate locked for 12 months, and a live answering line within 14 days

refund · Refunded in full if the line is not answering calls within 14 days of payment; after the first month, cancel any time with no contract

target · 8 prepaid first months from 20 shop visits within 30 days

before taking money · Record or transcribe customer calls only with the consent notices two-party-consent states like California require, and route job deposits into each shop's own Stripe account rather than holding funds, which would raise money-transmission questions before counsel reviews them.

Go: build it if

10 of 20 shops sign the reciprocal passing agreement, 8 prepay $199, and at least 5 real jobs are passed and accepted during the two-week live test

Kill: stop if

Fewer than 4 of 20 shops agree to outbound passing (the network premise is dead and what remains is a commodity answering bot), or fewer than 3 prepay, or zero passed jobs are accepted during the live test

outreach message

Every after-hours call your shop misses is a job for whoever answers first the next morning. I'm signing six independent shops on your side of town for a live test: a line that answers after hours, books straight into your calendar, takes the deposit, and when you're full or it's the wrong make, passes the job to a member shop nearby - and pays you 10% when jobs pass back to you. First month is $199, and I'll show you every call transcript. Got 20 minutes at the shop this week?

Answer every call. Booked solid? Pass the job and keep 10%. $199 prepays your first month and locks the founding rate for 12 months Prepay your first month - full refund if you're not live in 14 days

deposit terms

Your $199 covers your first month, locks the founding rate for 12 months, and reserves your shop's spot in the metro passing network. Full refund if your line is not answering calls within 14 days of payment. After the first month you can cancel any time; there is no contract.

The idea in full

What: Passline answers calls, texts and web chats for small service businesses (auto shops, installers, salons, plumbers), books jobs into their existing calendar, and takes deposits. When the shop is full, out of stock or out of area, the agent hands the job to another Passline business nearby and both sides split the fee. Sold per seat per month plus a cut of every passed job, live in a day through Google Business Profile, Stripe and the shop's booking tool.
Why now: The current cohort is betting on exactly this surface: TryNearby (yc S26) and CarSignal (yc S26) are both selling software into local operators, Flip just raised $25.0M (2026-08-19) for frontline workers, and Weibook died in 2023 doing bookings for beauty businesses without any cross-shop layer.
Wedge: first customer and entry point: Independent auto repair shops in one metro: answer after-hours calls, then route the jobs a shop refuses (wrong make, no lift free this week) to the shop two streets over.
Path to 100x: AI receptionists for local services are a $3-8B software market, but the pass-through layer turns it into a two-sided one: each new shop raises the fill rate for every other shop in the same postcode, so the first network to reach density in a trade owns it and takes a percentage of job value on top of seats. Distribution comes through POS, booking and franchise partners who resell it to thousands of locations at once, in every English, Spanish and German speaking market from day one.
Ceiling: Passing works only inside dense same-trade clusters, so the network is really hundreds of small city-by-trade networks that never compound into one.
Closest real companies, as the generator saw them: CarSignal builds an operating system inside a single auto shop and TryNearby connects businesses to creators; Passline is thinner inside the shop and only owns the inbound conversation, but it is the only one that moves a rejected job to another member.
Main risk: Shops treat the neighbour as a competitor and switch off outbound passing, leaving a plain answering bot with no network.

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
Capital-light with revenue inside a year, but the $3-8B receptionist market plus city-by-trade network fragmentation limits the upside.
Bootstrapper
5/5
Capital-light, live in a day on Google Business Profile and Stripe, revenue within a year from auto shops already paying answering services.
Operator
5/5
Missed after-hours calls are lost revenue an auto shop owner feels personally, live in a day on Google Business Profile and Stripe.
Technologist
1/5
A receptionist bot on Google Business Profile and Stripe with a referral split; nothing here takes longer than a weekend to rebuild.
Risk
2/5
Runs entirely on Google Business Profile, Stripe and the shop's booking tool, in a receptionist category already crowded where Weibook died.
trends
2/5
AI receptionists were buildable in 2024 and vertical agents are the most crowded cluster at 25% of S26; the pass-through twist adds no new enabler.
