From early readers
I can see clear value in here. There is a ton of content — I'm quite shocked that it's so free. The first two chapters were amazing.

The method

Measure, keep, then grow

One operating model, taught in the order the work runs — written for founders wearing the growth hat, consultants setting it up for clients, and people breaking into the field.

  1. Measure

    Instrument PostHog so you can actually see what's happening — the events, the funnels, and the leaks in your bucket.

  2. Keep

    Turn one-time visitors into retained users with lifecycle messaging you build in code with Hogsend.

  3. Grow

    Drive traffic that compounds, and capture every visitor into an audience you own — not one you rent.

What's inside

Quizzes, flashcards, a workbook, and a plan

Every chapter has a quiz and a flashcard deck; the workbook runs through the whole course.

A workbook, not highlights

Everything you type — check-ins, writing prompts, calculator read-outs — saves to one page on your account. You finish with your numbers and your plan, not a pile of notes.

Quizzes & flashcards that stick

Every chapter ends with a quiz that samples fresh questions from a bigger pool, plus a flashcard deck written as full answers — retakes test the ideas, not your memory.

Your 30/60/90/180 plan

The final chapters assemble your workbook answers into a staged plan for days 0–180 — the thing you actually run after the course.
