WHAT THIS IS: the full organic growth system for SaaS in one guide. Ten parts, in the order users move: who they are, what you offer, how they find you, why they sign up, why they stay and why they bring their team. Every part has chapters, ready Claude prompts, templates to fill in, workflows that chain the prompts, and an audit to check your work.

WHO IT'S FOR: founders, CMOs, heads of growth, product marketing and lifecycle leads at B2B and B2C SaaS.

HOW TO USE IT: go part by part. Fill the templates (T), run the prompts (P), follow the workflows (W) and finish every part with its audit (A). Each prompt names the template it fills.

WHY CLAUDE + XERJ

Claude is great at the work: research, positioning, copy, scripts, analysis. It gets weak when you paste 3,000 reviews, a year of support tickets or 50 CSV exports into one chat: the context fills up and answers get vague.

XERJ is a free, open-source search engine for AI agents. It runs locally, indexes a folder of files (docs, PDFs, CSV, transcripts, exports) and lets Claude search that folder instead of loading everything. Claude pulls only what each question needs and answers with the source.

Set it up once (Claude Code):

curl -fsSL https://xerj.org/get | sh
claude mcp add --scope user xerj -- xerj mcp
xerj autoindex ./growth-data

Put everything in one growth-data folder, one subfolder per source:

Folder	What goes in
/reviews	G2, Capterra, app store and marketplace reviews
/support	Support tickets and chat exports
/calls	Sales and user interview transcripts
/competitors	Competitor pages, pricing, changelogs
/content	Your posts, scripts and their numbers
/metrics	Weekly exports: signups, activation, retention, revenue

Re-run xerj autoindex ./growth-data after you add files. Store the Brand Context below in XERJ memory once, and every new Claude session can recall it.

THE RULES

Real data only. Claude writes [NEEDS INPUT: what] instead of guessing numbers, quotes or results.
Cite the source. Every insight from XERJ comes with the file it came from.
Users who stay are the goal. Judge every channel by activated and retained users, not by visits.
One change at a time. Every experiment has one variable and a pass line.

Paste this at the start of every Claude session:
