The Details

What's inside

Every significant product decision has a type. Type 1 decisions are irreversible — once you commit, walking back costs you everything. Type 2 decisions are reversible — wrong call, come back, try again.

This guide documents the framework Jeff Bezos described in his 2015 shareholder letter, how Amazon applied it to launch Prime and AWS, and how I used it to make Hookem's first major product decision: Instagram-only positioning.

Includes a 5-question checklist you can run through any decision before you commit — and a breakdown of how to identify which type you're dealing with.

Who this is for

Solo builders who move fast and regret decisions they can't undo
Developers choosing platforms, tech stacks, or business models without a framework
Engineers inside companies who want to apply this to their own side projects
