These courses teach the opposite order: measure what is actually happening, keep the users you already won, then grow on top of a product that holds.
“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.”
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.
Measure
Instrument PostHog so you can actually see what's happening — the events, the funnels, and the leaks in your bucket.
Keep
Turn one-time visitors into retained users with lifecycle messaging you build in code with Hogsend.
Grow
Drive traffic that compounds, and capture every visitor into an audience you own — not one you rent.
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.
Common questions
The short version: first lesson free, one-time pricing, lifetime access.
Yes. The first lesson of every course is free to read with no account at all — and the flagship course gives away its first two chapters in full. Paid courses unlock the rest with a one-time purchase; free courses just need a free account.
