Proof, filed.
One Super Bowl spot, aired once, that repositioned a computer company as a counterculture. The most-studied launch ad ever filmed.

The margin notes.
Almost any question can be answered, cheaply, quickly and finally, by a test campaign.
The aim of marketing is to make selling superfluous.
A growth hacker is a person whose true north is growth.
Half the money I spend on advertising is wasted. The trouble is I don’t know which half.

Claim: the library totals an estimated 38.6 million words — roughly sixty-five copies of War and Peace. Source: RGM analysis, June 2026, stratified 300-page sample. Context: scale is a by-product of the format — one focused sheet per question, never one page stretched across many.
How the library is built.
Sourced, or labeled.
Every number links a public source — SEC filings, Cannes archives, Think with Google, the business press — or carries the label “RGM analysis.” A claim that fails both tests gets cut.
STAR case files.
Situation, Task, Action, Result. Each file ends with an honest note naming what the public record cannot verify. Guesses do not ship.
Plain language wins.
Guides target a grade 5–7 reading level. Short sentences. Concrete nouns. If a simpler word survives review, the longer word loses.
Named examples only.
Real brands, real dollar figures, dated events — Old Spice in 2010, Apple in 1984, Wrapped in 2017. Vague “a leading brand” prose gets rewritten.
Open stacks, machine-readable.
No gated PDFs. No email walls. Every sheet ships a markdown twin, so AI assistants can read the library directly. Ask yours about this page.
Revised in public.
Parallel editorial lanes ship weekly. The changelog records every release, and the census on this sheet is dated so you can judge freshness.
If you only read seven sheets
- Define the discipline. What growth marketing is, what it is not, and where the role ends.
- Learn the audience first. Pain, Desire, Aspiration — research that precedes every dollar of spend.
- Know your number. CAC payback is the heartbeat metric. Months, not vibes.
- Build clean structure. Account architecture decides what the algorithms can learn.
- Question your credit. Attribution models disagree on purpose. Know why before trusting one.
- Prove cause, not click. Holdouts and geo tests settle the arguments dashboards start.
- Compound what you keep. Lifecycle turns one purchase into a durable revenue line.
Asked & answered.
- What is this page?
- The index sheet for the RGM growth marketing library — the hub that routes you into 27,139 pages of guides, case files, frameworks, and benchmarks. Think of it as the drawing register for the whole collection.
- Who writes the library?
- Senior practitioners at Real Growth Matters. The same team that runs audits and media programs writes the sheets, which is why the examples carry real numbers and the advice takes sides.
- What separates growth marketing from performance marketing?
- Performance marketing buys measurable outcomes inside ad platforms. Growth marketing owns the wider system — audience, offer, funnel, retention, and the math connecting them. The growth marketing pillar and the performance marketing pillar draw the border precisely.
- Does any of this require an account or an email?
- No. Open stacks are the standard here — no gates, no lead magnets, no PDF ransoms. Copy what helps, cite the page, and keep reading.
What is growth marketing?
Growth marketing is the discipline of growing revenue across the full customer journey — acquisition, activation, retention, referral, and pricing — using research, experiments, and measurement. Performance marketing buys outcomes inside ad platforms; growth marketing also fixes the funnel, the offer, and the math behind both. Start with the pillar guide for the full picture.
How big is the RGM learn library?
The June 2026 census counts 27,139 pages across 86 stacks — an estimated 38.6 million words. That includes 2,760 STAR-structured case files, ten load-bearing pillar guides, and deep stacks for strategy, concepts, measurement, channels, and tactics. Sister sections add 10,655 glossary definitions and 135 calculators.
How is the learn library organized?
Hub and spoke. This page is the hub. Ten pillar guides carry the core ideas, and 86 stacks group every other page by discipline — channels, measurement, creative, verticals, operations, and the case-file archive. Every spoke links back to its pillar, so you can climb from any page to first principles.
Where should I start reading?
Start where it hurts. Rising acquisition costs point to the CAC payback pillar. Murky numbers point to attribution and incrementality. Greenfield projects start with the growth marketing pillar, then the PDA audience framework. Or state your model and bottleneck in the dispatcher above and take the three-step path it returns.
How do I find one specific topic fast?
Press Ctrl K — Cmd K on a Mac — anywhere on this site to open instant search. It forgives typos, understands synonyms, and ranks results across 21,000+ indexed pages. The register on this page also filters all 86 stacks as you type. Both beat scrolling.
How are the case studies researched?
Every case file follows STAR — Situation, Task, Action, Result — and cites public sources such as SEC filings, the Cannes Lions archive, Think with Google, and established business press. Numbers the public record cannot verify carry an honest note instead of a guess. Invented metrics do not survive review.
Can I cite or share this content?
Yes. Cite freely with attribution and a link to the page you quote — copied text appends its source automatically. Every sheet also ships a markdown twin, so AI assistants and answer engines can read the library directly. The terms page covers licensing beyond fair use.
How often does the library update?
Continuously. Parallel editorial lanes ship new batches weekly, and the changelog records every release. The census on this page is dated June 2026 and refreshes with each revision. Stack counts move as new sheets land, so read every count as a floor, not a ceiling.
