Digital Products, in three books

For: you have never sold a digital product — maybe not even an idea yet.

You finish with: one product made, listed, priced and delivered, and either a first sale or a clear, written reason there wasn't one.

Eleven chapters on making something with no stock and no shipping: what actually sells, the platform-fee reality most sellers get wrong, pricing as a statement about how much traffic you need, and the licensing rules that quietly get listings pulled.

For: you have one product listed and measured, and no second sale from the same buyer.

You finish with: a 3–5 product range for one buyer, an email list, and a sequence that sells while you're away.

Thirteen chapters on turning one product into a range: the staircase of offers, the free thing that earns an email address, the five-email sequence that sells unattended, and the seven-number scorecard that tells you which part of the machine is working.

For: you have a range that sells, with repeat purchase happening, and growth has flattened.

You finish with: a premium tier that justifies its price, launches that work, and a catalog run by cohort economics rather than by feel.

Twelve chapters on the ceiling: the premium offer and how to price it, launches that don't burn the list, paid acquisition that doesn't quietly lose money, and the durability audit that proves what you have actually built.
