ShipScore = the CENTS composite. C = control vs gatekeepers · E = barriers (high is good) · N = proven demand · T = income detached from hours · S = reach

At $39/mo (assumed category price), you need 2,137 subscribers for a $1M/yr pace.

Nearest tracked rivals on that curve:

• GojiberryAI — Verified $501k MRR in the same monitoring lane — capital, data and distribution you cannot match at $50/mo.
• Subreddit Signals — Verified $40k MRR proves the exact wedge is already taken and being marketed on X.
• F5Bot / free keyword alerters — Reddit keyword-to-email monitoring exists for free, anchoring perceived value near zero.

• Radar-tracked Subreddit Signals at verified $40k MRR shows people pay for Reddit intent alerts.
• GojiberryAI at verified $501k MRR confirms a large, monetized monitoring category — but also a dominant incumbent.
• 0 of 3 tracked similar products stall under $2k MRR, so the category clears the hobby threshold.
• Zero Reddit demand signals found for these keywords — no direct evidence solo marketers are asking for this specific product.

• Reddit's paid API terms and rate limits can reprice or revoke your entire data supply overnight.
• Facebook Groups has no lawful monitoring API; that half of the pitch is likely undeliverable or ToS-violating.
• Sub-$50 pricing against a $501k MRR incumbent leaves no budget for data costs or paid acquisition.
• Keyword alerts produce high false-positive noise; churn is brutal once Slack channels get muted.

• Reddit Data API pricing/terms — One policy update prices out or bans commercial keyword monitoring, as it did to third-party Reddit apps in 2023.
• Meta Platform Terms / Groups access — Scraping detection or a cease-and-desist removes the Facebook feature and the differentiation with it.
• Slack app directory review — Delisting or OAuth scope restriction severs the only delivery channel customers actually use.

• Cannot tell whether Subreddit Signals' $40k MRR comes from alerts or from its AI reply/agency layer.
• No visibility into actual Reddit API data costs at your query volume, which decides unit economics.
• Cannot verify whether any compliant Facebook Groups monitoring path exists for a small operator.

Scores judge the market and business model — not your ability to execute. Verified MRR = independently tracked revenue; reviews/upvotes = platform-reported. Judged 2026-08-03.

Pick one vertical (e.g. B2B SaaS founders hiring agencies), score intent with a trained classifier instead of keywords, and deliver a qualified-lead digest with drafted outreach — sell the reply, not the alert.

Cheapest next step: Manually run 20 buyer-intent queries across five target subreddits this week and hand-deliver a Slack digest to 10 solo marketers; charge $39 upfront and count who pays.

Business-model variations of this idea, engineered to beat 4.8 — different vertical, audience, model, or wedge. Same harsh scale.
