Latchwork

Self-healing connectors for the long tail of small business software agents cannot reach.

Latchwork records a session against a vertical tool that has no usable API - a dental scheduler, a salon booking system, a freight dispatch app - and turns it into a connector that agents call like an API, then repairs itself when the vendor changes a screen.

$1,600 · 6 weeks · 25 prospects

Prove for under $1,600 in six weeks that dental practices will prepay $100 to reserve a connector into Dentrix or Eaglesoft, and that dental IT shops will publish connectors for a revenue share.

1Focus group: who and where

Office manager or owner-dentist at an independent US dental practice (1-3 locations) running Dentrix or Eaglesoft alongside at least one AI or online tool, an AI phone answering service, online booking, or insurance verification, whose front desk rekeys appointments and patient records by hand every day. Secondarily, principals at dental IT and practice-management consultancies serving those same systems.

where to find 25 · AADOM (American Association of Dental Office Management) local chapters and its online member community; Dentaltown practice-management forums; r/Dentistry; LinkedIn Sales Navigator filtered to title dental office manager; AADOM Conference (September 2026) hallway outreach; consultancies via Dentaltown vendor boards and LinkedIn companies describing dental IT support for Dentrix and Eaglesoft.

2Sell first, build later

A working connector between your named tool pair, for example your AI phone service and Dentrix, live within 30 days of reservation, human-backed behind the scenes until the automation is reliable, with every write visible in a daily log your office manager can check.

the ask · $99 per month per connected tool, first month prepaid; $100 refundable reservation to get in the first cohort

a real yes · A real yes is a paid $100 reservation or a prepaid first month through Stripe. 'The front desk would love this,' free-trial requests, and agency compliments without a signed publisher agreement are not a yes.

3Small experiments

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

1. Rekeying cost interviews
$300 · 10 days
Book 15 calls with office managers recruited through AADOM chapters and Dentaltown, offering a $20 gift card. Get the exact tool pair, hours per week of rekeying, and errors per month, and end with a direct ask: would you pay $99 a month per connected tool to make this stop.
keep going if · 10 of 15 report 3+ hours per week of rekeying and name a specific tool pair; 8 say yes to $99 per month unprompted by discounts
2. Wizard-of-Oz connector
$400 · 21 days
For 5 practices from the calls, a founder behind a shared inbox and remote-desktop session writes every booking from their AI phone or online booking tool into Dentrix or Eaglesoft within 15 minutes, during business hours, for 2 weeks. It looks like a connector; it is a person. Week 3 starts billing.
keep going if · 4 of 5 practices convert to paying $99 per month when billing starts in week 3
3. Agency publisher pitch
$0 · 21 days
Pitch 10 dental IT consultancies on publishing and maintaining connectors in the Latchwork directory for 30% of every subscription on their connectors. The pitch deck shows the Wizard-of-Oz results and the recording-to-connector flow. Ask for a signed publisher agreement, not interest.
keep going if · 3 of 10 sign a publisher agreement and commit a named person to build one connector
4. Reservation page
$550 · 14 days
A landing page listing the first 20 planned connectors for Dentrix and Eaglesoft tool pairs at $99 per month per connected tool, with a $100 refundable reservation via Stripe Payment Link. Drive traffic from the interview list, AADOM community posts where rules allow, and $350 of Facebook ads targeted at dental office managers.
keep going if · 8 paid $100 reservations, at least 5 from practices not already interviewed

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.

$100

per prospect, refundable

how · $100 refundable reservation collected through a Stripe Payment Link on the landing page and on calls, converting to the first month of the $99 subscription at go-live set up: Stripe Payment Links ↗

what it reserves · A slot in the first 20-practice cohort, their exact tool pair built first, and the $99 per month price locked for 12 months

refund · Refundable in one click any time before the connector goes live, and refunded automatically if it is not live within 30 days

target · 10 paid reservations from 25 conversations plus page traffic within 5 weeks

Go: build it if

10 paid reservations, 4 of 5 Wizard-of-Oz practices paying at week 3, and 2 signed agency publishers: build the recorder and self-healing layer.

Kill: stop if

Fewer than 3 reservations from 25 conversations, or fewer than half of practices report 3+ hours per week of rekeying, or 0 of 10 agencies sign: the pain is real but not worth $99 a month, stop.

The idea in full

What: Latchwork records a session against a vertical tool that has no usable API - a dental scheduler, a salon booking system, a freight dispatch app - and turns it into a connector that agents call like an API, then repairs itself when the vendor changes a screen. Small businesses subscribe per connected tool; the agencies and vertical resellers who already implement those tools publish connectors into the Latchwork directory and take a share of every subscription. Building a connector is recording and mapping, no code, which is why the supply side can be non-engineers.
Why now: Y Combinator's Fall 2026 Requests for Startups names Self-Maintaining APIs directly, and the crowded-phrase data shows this cluster's last two years concentrated on coding agents (5 companies) and open source tooling (7 companies) - the long tail of small business vertical apps with no API at all is where the RFS points and where nobody is working.
Wedge: first customer and entry point: One vertical with a dominant no-API incumbent, starting with independent dental practices: ship twenty connectors for the top scheduler and billing tools, and recruit the three implementation agencies that already serve those practices as the first publishers.
Path to 100x: Small business vertical software plus the manual work around it is a $100B+ market, and every connector Latchwork ships makes the platform more valuable to the next agency and the next agent vendor building on it. The data moat is the accumulating record of UI change deltas across tens of thousands of long-tail apps - that history is what makes connectors heal automatically, and a new entrant starts with none of it.
Ceiling: If the top hundred connectors cover most demand, the long tail never monetizes and this settles as a mid-sized integration vendor rather than a platform.
Closest real companies, as the generator saw them: Executor is the open source integration management layer for AI and Rindler is the translation layer between agents and the web; both aim at general developers and general web surfaces, while Latchwork is a no-code connector marketplace for named vertical SMB applications, published and maintained by the agencies who know them. Context.dev supplies realtime web context, not durable write access to a specific tool.
Main risk: General computer-use models get reliable enough that agents drive these apps directly and pre-built connectors lose their reason to exist.

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
Capital-light no-code connectors where accumulated UI change deltas across tens of thousands of long-tail apps is a data moat a new entrant lacks.
Bootstrapper
4/5
No-code connectors published by dental implementation agencies means software margins, per-tool subscriptions and a supply side that costs nothing.
Operator
4/5
Dental schedulers with no API are a concrete daily blocker, and the implementation agencies already serving those practices publish and sell connectors.
Technologist
4/5
The corpus of UI change deltas across thousands of no-API vertical apps is what heals connectors, and a new entrant starts with none of it.
Risk
1/5
Connectors are recorded sessions against vendors' UIs, so every one of those vendors can break or forbid it through terms.
trends
4/5
Why-now lands on the Fall 2026 Self-Maintaining APIs RFS with a concrete whitespace claim, and agent demand for no-API SMB tools is genuinely new.
