GroupSignal

Monitors Reddit and Facebook Groups for buyer-intent keywords and sends lead alerts to Slack; billed monthly under $50 for solo marketers and small B2B/DTC teams. · Community Lead Monitoring

DEAD SLOW · CAUTIOUS

4.8 ShipScore / 10

Strongest is automation; weakest is control — Reddit API and Facebook own your lifeline.

Condition: Only build if you drop Facebook Groups, license Reddit data compliantly, and win on vertical intent scoring plus CRM workflow rather than raw keyword alerts.

Part I — The Verdict what the instruments read

01 — The ShipScore breakdown

Control

Entry barriers

Need

Time-freedom

Scale

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

Nearest tracked rivals on that curve:

Part II — The Evidence the receipts, good and bad

03 — Rival scan — corpus tracks 3 similar

GojiberryAI	verified MRR $501k · CENTS 7.6 (trustmrr)
Subreddit Signals	verified MRR $40k · CENTS 5.4 (x)
Flightview - Flight Tracker	6340 reviews · 3.7★ (appstore-us)

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.

04 — Demand evidence

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.

05 — Risks

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.

06 — Kill switches — what kills this with one decision

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.

Part III — The Plan if you insist on proceeding

07 — What this scan can't tell you

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.

08 — The wedge & the next step

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.

Not quite it? Spin the model

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