White-label SaaS marketplace builder for solopreneurs to launch niche two-sided marketplaces (courier, workforce, dating) in days at $49/mo per instance. · Marketplace-in-a-Box SaaS
Condition: Only revisit if you pre-sell 20 paid instances in one vertical (e.g. courier ops with dispatch + Stripe Connect payouts baked in) before writing code — generic builders lose to Sharetribe.

What the five commandments measure
C — Control
Do you own the customer, or does a gatekeeper (an app store, an algorithm, one platform) stand between you and revenue? High = you hold the keys.
E — Entry
How hard is this to copy? High barriers protect you once in — but a well-loved incumbent means breaking in is expensive, and scores this low.
N — Need
Is demand proven with money, not vibes — verified rival revenue, funding, exit multiples, complaint volume? No market evidence caps this at 5.
T — Time
Can income detach from your hours? High = earns while you sleep; low = you bought yourself a job.
S — Scale
How far does it reach without linear cost? High = software margins to thousands of customers; low = growth means headcount.
ShipScore = the mean of the five, scored by Opus 5 on the evidence below — the same rubric for every idea, including the ones we generate ourselves. Inspired by MJ DeMarco's CENTS framework. Full rubric →
02 — The pace test — $1M/yr
At $99/mo (assumed category price), you need 842 subscribers for a $1M/yr pace.

Sharetribe — Established, well-loved marketplace-in-a-box with hosted + open-source tiers; owns the search term and community.
Bubble / no-code marketplace templates — Marketplace templates cost near-zero and let solopreneurs self-build, collapsing your price ceiling.
White-Label Community SaaS (listed at $235k on $137K TTM profit) — Proves buyers can acquire a working white-label platform outright instead of renting yours at $49/mo.
04 — Demand evidence
Corpus evidence is adjacent, not direct: no tracked marketplace-builder has verified MRR — the $39k ChatDash and $4k Whitelabel AI Assistants figures are chatbot/AI tools, not marketplace software.
Zero Reddit demand signals found for these keywords — no visible complaint or 'looking for' volume to ride.
White-label SaaS resale demand exists though: a White-Label Community SaaS listed at $235k on $137K TTM profit, plus CRM and auto-tuning white-label exits.
No funded companies tracked in-space here, but general market knowledge shows entrenched paid incumbents (Sharetribe, Arcadier, Yo!Kart) already charging $99–$299/mo.
Two-sided marketplaces overwhelmingly fail to reach liquidity; your customers churn when their marketplace dies, not when your product fails.
$49/mo ARPU cannot fund support for three wildly different verticals (courier, workforce, dating) — each needs distinct payments, verification and matching logic.
Trust-and-safety exposure: dating and gig-workforce instances on your infrastructure make you a target for moderation, fraud and liability complaints.
Feature-parity race against free Bubble templates and open-source Sharetribe with no proprietary data or network effect to defend.
06 — Kill switches — what kills this with one decision
Stripe Connect / payment processor policy — Marketplace payouts run through Connect; a risk-team ban on your platform account freezes every tenant's money at once.
Apple/Google app stores (if tenants need mobile apps) — Courier and dating instances need apps; store rejection of cookie-cutter white-label clones blocks the whole distribution promise.
Sharetribe or Bubble launching a $49 tier — One pricing decision from an incumbent erases your only differentiator, since the tech itself isn't defensible.

Part III — The Plan if you insist on proceeding
07 — What this scan can't tell you
Cannot tell your actual churn curve — how long a solopreneur keeps paying after their marketplace fails to get liquidity.
Cannot verify whether any tracked white-label listing's profit came from subscriptions or one-off lifetime licenses, which changes the model entirely.
No data on vertical-specific willingness-to-pay: courier ops may pay 5x what a dating hobbyist pays, and this scan can't separate them.
Scores judge the market and business model — not your ability to execute. Verified MRR = independently tracked revenue; reviews/upvotes = platform-reported. Judged 2026-08-02.
08 — The wedge & the next step
Drop the three-vertical spread; own one operationally painful niche (e.g. same-day courier dispatch) with payouts, driver verification and routing pre-wired — sell to operators who already have supply.
Cheapest next step: Post a one-vertical landing page with a $99/mo pre-order deposit and DM 30 operators already running that niche on spreadsheets; measure deposits, not signups.
Not quite it? Spin the model
Business-model variations of this idea, engineered to beat 5.2 — different vertical, audience, model, or wedge. Same harsh scale. Pro feature.
