The Kellblog Companion
An unofficial, interactive companion to Kellblog — Dave Kellogg's writing on SaaS, marketing, and operating discipline, turned into things you can poke at.

A growing library
of operating wisdom,
made tinkerable.

A curated, interactive reading of Dave Kellogg's body of work — 10+ years each as CMO, CEO, and independent director, across companies from $0 to $1B+ — turned into things you can poke at, drag, and recompute.

§ THE LIBRARY

Two volumes, both interactive.

Each volume is a sequence of chapters — sliders, drag‑and‑drop, scrubbable charts — not an essay. Click a tile to enter; every chapter cites the underlying Kellblog post.

I.  Vol. 01 · Marketing

Make sales easier.

What marketing is for, how to staff it across the four pillars, when to say no, and how to keep your job long enough to do the work well.

"Marketing exists to make sales easier."— Dave Kellogg, career-long credo

Enter Vol. 01 →
II.  Vol. 02 · SaaS Metrics

The numbers tell the truth.

Five interactive readings of the metrics Dave has been arguing about for two decades — Rule of 40, Mendoza Line, Magic Number, NRR, and the burn multiple. Each one is a calculator, not a chart.

"If you can't measure it, you can't improve it."— Dave's analytical credo
