Test it before you build it
$1,000 · 3 weeks · 30 prospects
Prove 10 builders of agent-generated apps prepay $99 for small-app hosting, for $1,000 in 3 weeks.
Riskiest assumption · Builders who ship agent-generated apps feel per-app hosting cost as their own pain, sharply enough to prepay a year for a cheaper deploy target, rather than treating it as a pass-through line their clients absorb.
1Focus group: who and where
Solo developers and 2-5 person agencies that ship Lovable, Bolt, or Replit-generated apps for small-business clients, currently running 5-50 low-traffic apps and paying $15-25 per app per month in hosting they either absorb or awkwardly rebill
where to find 30 · Lovable's official Discord and its Launched showcase gallery (a browsable directory of builders with live apps), r/SideProject and r/lovable on Reddit, Indie Hackers, and the #buildinpublic stream on X where these builders post their app counts and hosting bills
2Sell first, build later
A founding membership in the small-app cloud: 25 app slots at $1 per app per month locked for 12 months, with your first 5 existing apps migrated for you by November 1, 2026
the ask · $99 per year founding membership, then $1 per app per month from app 26 onward
a real yes · A real yes is a completed $99 charge; waitlist emails, upvotes, Discord praise, and 'I would totally switch' are not
3Small experiments
The first one attacks the riskiest assumption; each ends with a number that says whether to run the next.
1. Hosting-bill interviews
$200 · 7 days
DM 30 builders pulled from Lovable's Launched gallery and the communities above, referencing a specific app they shipped, and book 15 calls. Ask for the actual number: apps running, monthly hosting cost per app, and what happens to a client app when the retainer ends. One founder runs all calls in a week.
keep going if · 8 of 15 run 5+ generated apps and pay $15+ per app per month, or say hosting cost has made them decline or kill client apps
2. Priced landing page
$500 · 10 days
One page: $1 per app per month for low-traffic apps, deploy by CLI, founding membership at $99 per year for 25 app slots with the price locked. Post it in r/SideProject, Indie Hackers, and #buildinpublic with the founder's own hosting-bill story, plus $300 of Reddit ads targeting r/webdev and r/SideProject.
keep going if · 250+ visitors with 8% or more clicking through to the $99 checkout
3. Founding cohort prepay
$300 · 14 days
Turn the checkout live: $99 charged today, 25 app slots, and the founders hand-migrate each member's first 5 apps onto a leased US bare-metal box by November 1, 2026. Lease one OVHcloud US server to honor the date and email every interviewee and checkout abandoner the offer directly.
keep going if · 10 paid $99 checkouts out of 25 checkout starts
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.

per prospect, refundable
how · A $99 prepaid founding membership taken at checkout on the landing page - the first-year-prepaid instrument fits because this buyer already pays for hosting monthly by card and a self-serve API product should be sold self-serve from day one set up: Stripe Checkout ↗
what it reserves · A founding slot: 25 app slots at $1 per app per month locked for 12 months, plus hands-on migration of the member's first 5 apps by November 1, 2026
refund · Full refund on request any time before the member's first app is live, and automatic refund to everyone if the platform is not live by November 15, 2026.
target · 10 paid $99 memberships from 30 direct conversations plus landing traffic within 21 days
Go: build it if
10 or more $99 prepays and 8 of 15 interviews confirming $15+ per app per month spend across 5+ apps
Kill: stop if
Fewer than 4 prepays after 30 DM conversations and 250+ landing visitors, or interviews showing builders pass hosting costs to clients without friction
5 Scripts to run itoutreach message, landing copy, deposit terms · click to open
outreach message
You ship Lovable and Bolt apps for clients, and every 10-user app still costs you $20 or more a month to host, forever. I am building a deploy target priced for small apps: $1 per app per month for the sleepy ones, sub-second wake on traffic. Founding members pay $99 for the year, lock that price for 25 app slots, and I migrate your first 5 apps for you by November 1. Got 20 minutes this week to walk through your hosting bill?
landing page
Hosting priced for apps with ten users. $99 a year: 25 app slots at $1 per app per month, locked for 12 months, first 5 apps migrated for you by November 1. Reserve your founding slot - $99, refundable until your first app is live.
deposit terms
Your card is charged $99 today, which buys a founding slot: 25 app slots at $1 per app per month locked for 12 months, with your first 5 apps migrated by November 1, 2026. Full refund on request any time before your first app goes live, and an automatic refund if we are not live by November 15, 2026. The $99 credits in full against your first year.

The idea in full
- What
- Miniplex is purpose-built cloud infrastructure for agent-generated software: sub-second cold-start microVMs, per-app metering in fractions of a cent, and a deploy API that coding agents and app builders call directly. It owns and tunes its own hardware fleet for extreme density - thousands of mostly-dormant apps per host - so a small business can run software used by ten people at a price no general-purpose cloud can match. Builders sign up self-serve; the API is the product.
- Why now
- Lovable raised $400M on 2026-08-12 to fund its development platform, YC's Fall 2026 RFS explicitly calls for 'A Cloud for Small Software', and smol machines (YC X26) is shipping portable self-contained VMs - the generated-app flood is here but it still lands on clouds priced for apps with millions of users.
- Wedge: first customer and entry point
- Become the default deploy target for one mid-size AI app builder's output; a 1-3 person team can start with a single leased rack running a custom microVM scheduler and one integration.
- Path to 100x
- Cloud infrastructure is a $10-100B-plus spend, and 'the small software cloud' is a genuinely new category: the first provider whose deploy API gets baked into the major codegen tools becomes the default runtime for millions of apps nobody else can host profitably. Defensibility compounds with scale - density economics improve with fleet size and every hosted workload teaches the scheduler - even though on day one there is no moat.
- Ceiling
- If generated apps consolidate onto a few builder platforms that vertically integrate their own hosting, Miniplex is left with the unaffiliated long tail only.
- Closest real companies, as the generator saw them
- smol machines makes VMs portable but does not operate the cloud they run on; Hoplite deploys software factories rather than hosting their output; Lovable and Prized generate apps and are customers, not competitors.
- Main risk
- The big clouds add a small-app tier priced at cost before Miniplex reaches the fleet scale its economics depend on.
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
A $10-100B cloud spend where density economics compound with fleet size is genuine power-law upside, discounted by zero day-one moat.
Bootstrapper
1/5
Owning a tuned hardware fleet to undercut hyperscalers on price is the exact capital-heavy, price-collapsing bet this lens avoids.
Operator
2/5
No buyer feels this pain personally - it needs codegen platforms to bake in the deploy API before any small business benefits.
Technologist
4/5
A custom microVM scheduler on owned racks is genuine systems work, and density economics improve with every dormant app hosted.
Risk
2/5
No moat plus a leased-rack capex bet whose demand arrives only if one mid-size AI app builder keeps pointing its deploy API at Miniplex.
trends
5/5
Nails the Fall 2026 'A Cloud for Small Software' RFS plus Lovable's 2026-08-12 $400M; only needed now, and big clouds haven't shipped a small-app tier.
