Your conversion tracking is broken. You just don't know it yet.
TagMedic is a free 60-second tracking-health grader and a $49/mo monitor that alerts SMBs the day their GA4, Google Ads tag, Meta Pixel, or consent setup silently breaks — instead of 30 to 90 days later, when the P&L finally tells them. It is the RankPrompt playbook applied to Anderson Collaborative's deepest competence: a self-service front door that monetizes the long tail and routes broken accounts with real ad spend straight into agency retainers.
Grader in the front, monitor in the middle, agency in the back
The problem
Tracking breaks silently — GTM publishes, consent updates, platform changes — and owners discover it 2 weeks to 3 months later, after smart bidding has death-spiraled. Verified complaint threads are perennial across r/PPC, r/googleads, r/GoogleAnalytics. The state-of-the-art fix people are told to use is a DIY blog tutorial.
The mechanic
URL in → headless scan → A–F grade with evidence-backed findings, ungated. Email gates only the PDF. $49–199/mo buys daily scans and the alarm: an alert the day anything stops firing. WordStream ran this grader-to-monitor architecture 1M+ times to a $150M exit.
The moat
Every critical finding carries a "fix it for me" button backed by the agency that has diagnosed this failure dozens of times at retainer prices. SaaS competitors cannot copy the human seam; agencies cannot copy the product. AC owns both sides.
Six candidates scored, one clear winner
Seeded from the AC/Nativz asset inventory (GTM MCP, ads tooling, headless-browser infra, tracking incident log), then pressure-tested by three parallel research agents.
| Idea | Demand | Agency fit | Build | Diff | Composite | Verdict |
|---|---|---|---|---|---|---|
| Tracking Health Grader + Monitor | 9 | 10 | 9 | 7 | 8.6 | ACTIVE — winner |
| Feedback / approvals tool | 8 | 8 | 8 | 7 | 7.8 | Already in flight (ac-site-feedback) |
| True-ROAS verifier (OAuth) | 8 | 9 | 6 | 7 | 6.8 | Parked — V2 expansion |
| Ads Waste Grader | 7 | 8 | 6 | 4 | 6.4 | Parked — WordStream-saturated |
| Local AI-visibility grader | 6 | 7 | 7 | 4 | 6 | Killed — cannibalizes RankPrompt |
| Martech stack scanner | 5 | 6 | 8 | 3 | 5.5 | Killed — Wappalyzer commodity |
Founder-market fit is literal: the agency's own incident log — a GTM thank-you-trigger break that tanked a client's lead flow, ad spend attributed to the wrong Google account, a full tracking rebuild after a domain cutover — is the demand evidence, already diagnosed at retainer prices.
Crowded scan layer, empty monitor layer
Eleven competitors mapped. Everyone under $150/mo either gives the scan away to sell something else, or sells audits without the alarm. Nobody sells the alarm.
| Competitor | Pricing | Target | Fatal gap vs TagMedic |
|---|---|---|---|
| ObservePoint | $599–$2,400/mo | Enterprise governance | 10–80x price; sales-led; config goes stale |
| DataTrue | $999–$1,999/mo | Enterprise QA | Annual-only; test-authoring complexity |
| Trackingplan | Free → $249/mo | Mid-market analytics | Snippet install; no rung between $0 and $249 |
| Code Cube | ~€150/mo | Mid-market EU | Requires dataLayer / sGTM integration |
| Elevar | $225–$3,000/mo | Shopify D2C | Shopify-only; pipeline, not auditor |
| TrackBee | €79–449/mo | Shopify SMB | Shopify-only; revenue-scaled pricing |
| AuditTags | $49 once · $79/mo | SMB | No free scan; no real-time alerts; zero brand |
| Rundata AI | $0 → $49–149/mo | SMB / agencies | Credit-metered audits, not alerting; gated results |
| Tag Assistant / Pixel Helper | Free | Practitioners | Session debugging; no grade, history, or alerts |
| Free scanners (Tracklution, Stape, Conversios…) | Free | SMB | Lead magnets for other products; none sells monitoring |
Voice of the customer (verified, verbatim)
"My avg daily conversion was 100ish... since yesterday it dropped to 2 and 0. I made no change."
"It was a little over 30 days before we realized the problem was not going to resolve itself."
"I had broken tracking for 3 months... the volumes didn't go back up."
"Is there any monitoring script that sends an alert when a tag stops firing?"
"Need help with conversion tracking — will pay $$."
"We hired multiple people from Fiverr and Upwork... none of them actually fixed it."
ICP priority stack
5–30 client accounts. One upstream change breaks many clients at once; reputation risk. Buys Agency tier + white-label reports.
Lead-gen site (home services, legal, medical, auto). Forms + calls on Squarespace/Wix/WP — the underserved stack. Crisis-moment searcher; buys Monitor.
Buys for job security: a credible artifact proving the drop is not their fault. Fewer complaints online, real budget authority.
GO — and the bear case is insured by the agency
The SaaS clears 3:1 on its own in the base case. The agency pipeline stacked on top means even the bear case lands near break-even — one closed tracking retainer per month pays the product's entire CAC.
Pricing — flat tiers, ad-spend-insurance framing
| Tier | Price | Who | What you get |
|---|---|---|---|
| Free Scan | $0 | The crisis-moment searcher | Instant URL-in graded report · GA4, GTM, Ads tag, Meta Pixel, consent mode · ungated results, email-gated PDF |
| Monitor | $49/mo | SMB owner | 1 site · daily scans · email/SMS alert the day something breaks · 30-day re-grade |
| Pro | $99/mo | In-house marketer | 3 sites · Slack alerts · weekly digest · CAPI + Enhanced Conversions + Consent v2 depth checks |
| Agency | $199/mo | Agencies / freelancers | 15 sites · white-label PDF · client-facing alerts · priority queue |
Research note: $9–15/mo positions you as commodity uptime infra (brutal churn); $49+ framed as "protects your ad spend" is the defensible register. Never market this as a pinger for your pixel.

Judge, don't debug — and show the evidence
Every observed competitor pain maps to a product principle: instant judgment (A–F grade in dollars), zero install, always fresh, and evidence attached to every finding — because this buyer has been burned by fixers who claimed success and delivered nothing.

TagMedic — the medic for the crisis moment
36 candidates checked against live registry RDAP on 2026-07-02 (real WHOIS, never assumed — the Brevlo lesson). Three finalists are fully available across all four TLDs.

Matches the acquisition moment (someone searching "tracking not working" wants a medic, not an alarm), supports the grade-as-diagnosis metaphor end-to-end (symptoms → vitals → treatment), and hands the agency the surgeon role. Register tagmedic.com + tagmedic.app immediately — sub-$30 total, and this report circulating is itself squatter risk.

Four weeks: the scanner is the only novel engineering
Everything else is commodity — auth, Stripe, cron, email. The moat is the rules engine, authored from AC's real incident log rather than theory.

| Database | Supabase Postgres (scans, findings, sites, subs) |
| Auth | Supabase Auth — email magic link |
| Payments | Stripe — 3 flat tiers, no per-user pricing |
| Email / alerts | Resend — PDF report, break alerts, weekly digest |
| Analytics | GA4 + PostHog from day 1 (we are the demo) |
| Hosting | Vercel/Netlify app + Fly scanner workers |
| Lead routing | Webhook → ac-projects CRM on qualifying scans |

Two scoreboards: SaaS health and agency pipeline
The product succeeds even at modest MRR if the SQL pipe runs — judge blended contribution. Alert precision is the existential metric: a monitor that cries wolf churns instantly.
| KPI | Target |
|---|---|
| Free scans / month | 5,000 (mo 12) |
| Scan → email (PDF gate) | ≥ 25% |
| Email → paid | 2–5% |
| MRR | $14k (mo 12) |
| Blended churn | ≤ 4%/mo (mo 1–3 tracked separately) |
| LTV : CAC | ≥ 3:1 |
| Alert precision | ≥ 90% — the existential metric |
| Agency SQLs / month | 2+ |
| SQL → retainer close | 25% |
| Organic clicks, breakage cluster | 3k/mo |
SOSTAC loop: monthly rule-quality review → keyword expansion from GSC queries → learnings feed the next Situation analysis. The true-ROAS verifier (OAuth tier) triggers at $10k MRR.
