Real Growth Matters

The RGM Appendix

Marketing Tools, People, Communities & Resources

A curated directory of the tools, thought leaders, communities, podcasts, and newsletters worth knowing. We list publicly known entities, link to their primary URLs, and write our own brief descriptions. We do not fabricate pricing or sentiment scores — the deeper pages mark verification fields explicitly.

About this directory. Entries are publicly known marketing tools, people, and resources. We provide brief, original descriptions and link to each entity's primary URL. We do not republish third-party pricing, review aggregates, or contact details — visit the entity's own page for the most current information. If you maintain one of these resources and would like to update or correct your listing, contact hello@realgrowthmatters.com.

How this directory is organized

Each top-level category has its own page with sub-categories. Within each sub-category, entries include a brief original description and a link to the entity's primary URL. We add new entries as they become relevant. We update existing entries when their offering materially changes.

This directory is intentionally not "every tool that exists." It is a curated list of resources we consider worth knowing for serious growth, performance, and digital marketers in 2026.
