// what this is

A program for product people who have outgrown the basics. You know how to write a PRD. You know how to run a sprint. What you don't yet have is a mental model for building products that scale without breaking.

This program teaches you how to think about your product as a system of domains, not a backlog of features. The result is a product function that moves faster, communicates more clearly with engineering, and makes decisions that hold up at 10x the complexity. if your background is design, this is the systems literacy that most design education skips entirely.

// what you'll learn

think in domains.
every conversation changes.

01
domain mapping
Map your product into bounded domains — and change every conversation you have with engineering.
02
domain discovery
Connect user problems to business domains, not just user stories.
03
prioritisation
Balance tech debt, domain ownership, and growth pressure in a single framework.
04
strategic roadmaps
Build roadmaps that communicate strategy — not just task lists.
05
product autonomy
Run a product function that doesn't need the CEO in every decision.
06
the codex OS
See how your product decisions connect to what ops, tech, and growth are building.
