Groundskeep
Monthly maintenance for shipped vibe-coded apps, applied as reviewable patches
Groundskeep watches the dependencies, API versions and platform deprecations behind a non-developer's shipped app, then opens plain-English patch proposals: what broke or will break, what the fix changes, one button to apply and one to roll back.

Test it before you build it
$500 · 3 weeks · 30 prospects
For $500 and 3 weeks, prove that owners of shipped Lovable apps will prepay $100 for maintenance they cannot verify themselves, before any monitoring code exists.
Riskiest assumption · An owner of a shipped Lovable app with real users will pay $39 a month, starting before anything visibly breaks, for patches they cannot personally read or verify - rather than waiting for breakage and re-prompting Lovable to fix it for free.
1Focus group: who and where
A non-technical founder whose Lovable-built app has been live 6 or more months with paying or active users, who just received a Stripe API version sunset or OpenAI model deprecation email they cannot parse, and who has no developer to forward it to.
where to find 30 · The Lovable Launched showcase (a directory of shipped apps - filter for ones live 6+ months with visible Stripe checkout or chat features, then find the maker on X), the r/lovable subreddit and the official Lovable Discord (communities where these owners post breakage complaints), and X #buildinpublic threads where makers announce Lovable launches (a channel with public DMs).
2Sell first, build later
A founding Groundskeep subscription sold before any product exists: monthly monitoring of the buyer's app dependencies, API versions and platform deprecations, delivered as plain-English patch proposals they approve, with the first health report and first applied patch inside 7 days of payment.
the ask · $100 prepaid for the first 3 months, then $39 per month per app, founding rate locked for 12 months
a real yes · A real yes is $100 charged to a card. Compliments, 'I'd definitely use this', requests for a free health report with no payment, and offers to try it once it launches do not count.
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Deprecation outreach and paid pitch
$100 · 10 days
Pull 30 live apps from Lovable Launched, run their public repos or stacks through npm audit and the published Stripe and OpenAI deprecation calendars by hand, and DM each owner the outreach script with one specific finding about their app. Book 15 calls; on each call walk through a one-page health report of their actual dependencies and ask for the $100 founding prepay on the spot.
keep going if · 10 of 30 DMs get a reply, 12 replies become calls, and 5 of 15 calls end with $100 paid
2. Founding checkout landing
$150 · 7 days
Put up a one-page site with the landing copy and a card checkout for the $100 founding prepay, and link it in every DM follow-up and in r/lovable and Discord threads where owners describe breakage. A card checkout fits because this buyer already pays Lovable monthly by card and there is no procurement step at $100.
keep going if · 3 or more checkouts from roughly 100 visitors (3%), counted separately from call-driven payments
3. First patch delivery test
$250 · 10 days
For every payer, deliver the promised service by hand within 7 days: a plain-English patch proposal for their most urgent outdated dependency, applied via a pull request to their GitHub repo with a written rollback step. Then ask each payer whether they want next month billed at $39 - this tests the card's stated risk that owners cannot trust patches they cannot read.
keep going if · 5 of 6 payers approve the patch without a support escalation and 4 of 6 confirm month-4 billing at $39
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 · A prepaid founding subscription taken by card at checkout on the landing page or on the call - the right instrument because this buyer is a solo online founder who already pays for Lovable, Stripe and OpenAI by card and can decide $100 alone in one sitting. The founder sends the checkout link during the call and watches it clear. set up: Stripe Checkout ↗
what it reserves · One of 20 founding slots, the first health report and applied patch within 7 days, and the $33-a-month founding rate locked for 12 months
refund · Fully refunded any time before the first patch is applied, or automatically if the health report finds nothing worth fixing.
target · 6 prepaid founding subscriptions from 30 owners contacted within 21 days
Go: build it if
6 of 30 contacted owners prepay $100 within 21 days, and 5 of the first 6 approve their first patch without escalation - build the monitoring product.
Kill: stop if
Fewer than 3 payments from 15 completed calls, or replies cluster on 'I'll just re-prompt Lovable to fix it when it breaks', or 2 of the first payers refund after seeing the report - stop.
5 Scripts to run itoutreach message, landing copy, deposit terms · click to open
outreach message
Saw your app on Lovable Launched - it looks live with real users, which puts you in rare company. I checked its stack: Stripe sunsets older API versions and OpenAI retires models on a schedule, and Lovable apps quietly break when that happens. I run a service that watches your app's dependencies and sends you plain-English patches you approve with one click. I already drafted a free health report for your app. Got 20 minutes this week to walk through what I found?
landing page
Your Lovable app will break. Know before your customers do. $100 prepays 3 months of monitoring and reviewed one-click patches, then $39 a month. Reserve one of 20 founding slots - refunded if your first report finds nothing to fix.
deposit terms
You pay $100 today, which covers your first 3 months and reserves one of 20 founding slots at $33 a month locked for a year. Your first health report and first applied patch arrive within 7 days. Full refund any time before your first patch is applied, and automatic refund if the report finds nothing worth fixing.

The concept in full
- What
- Groundskeep watches the dependencies, API versions and platform deprecations behind a non-developer's shipped app, then opens plain-English patch proposals: what broke or will break, what the fix changes, one button to apply and one to roll back. First hour: connect the GitHub repo Lovable exports to, get a health report of outdated and vulnerable dependencies, and apply the first low-risk patch with automatic rollback armed.
- Grounded in (2025-2026 signals)
- YC Fall 2026 RFS 'Self-Maintaining APIs'; Agent Skills 'released as an open standard on December 18, 2025' with 'about 40 products' supporting it by June 2026, so maintenance procedures can ship as versioned SKILL.md folders the user's own assistant executes; MIT NANDA (published August 2025) found 'more than 40% of knowledge workers use personal AI tools at work'.
- What it rides
- Self-Maintaining APIs: YC's Fall 2026 RFS describes exactly this, software that keeps itself compatible; Groundskeep sells that as a subscription the app owner runs, not an agent service that runs the owner.
- Why now
- Gartner predicted on June 25, 2025 that over 40% of agentic AI projects will be cancelled by end of 2027 for weak risk controls; the surviving pattern is the user-controlled one, and the Agent Skills standard of December 18, 2025 makes reviewable, versioned maintenance procedures installable in the roughly 40 products that support it.
- Wedge: first customer and entry point
- Owners of six-month-old Lovable apps whose Stripe or OpenAI API version deprecation notice just landed in an inbox they do not understand; $39 a month per app, first sold in the builder communities where 'vibe cod' appears in only 6 company pitches from the last two years.
- Closest real companies, as the generator saw them
- Attune (yc X25) speeds up builds for developers; StarSling (yc X25) runs CI for GitHub Actions users; Quantstruct (yc W25) maintains docs, not code. None sell maintenance to the non-developer who owns the app.
- Main risk
- An auto-applied patch silently changes app behavior and the non-technical owner has no way to notice until customers do.
