4.4 ShipScore / 10

Strongest: productized SaaS timing. Weakest: entry — free OSS gateways and native provider caching.

Condition: Only reconsider if you own a measurable cost-saving technique (semantic caching quality, cross-provider arbitrage) that free gateways cannot match, and target paying teams rather than indie devs.

What the five commandments measure
C — ControlDo 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 — EntryHow 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 — NeedIs demand proven with money, not vibes — verified rival revenue, funding, exit multiples, complaint volume? No market evidence caps this at 5.
T — TimeCan income detach from your hours? High = earns while you sleep; low = you bought yourself a job.
S — ScaleHow 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 →

§2 — The pace test — $1M/yr

At $25/mo (assumed category price), you need 3,334 subscribers for a $1M/yr pace.

Part III — The Plan if you insist on proceeding
§7 — What this scan can't tell you

Scores judge the market and business model — not your ability to execute. Verified MRR = independently tracked revenue; reviews/upvotes = platform-reported. Judged 2026-08-04.

§8 — The wedge & the next step

Skip the generic proxy; if anything, sell verified cost-reduction reporting and spend guardrails to funded AI startups whose finance team wants an audit trail, not to indie devs chasing free tools.

Cheapest next step: Post a concrete before/after token-cost teardown in two AI dev communities and count how many people ask to try it — a week of zero replies confirms the missing demand signal.

Not quite it? Spin the model

Business-model variations of this idea, engineered to beat 4.4 — different vertical, audience, model, or wedge. Same harsh scale.
