Subtract to Ship: Grow

How to grow a shipped product without adding the noise back

Growth that holds is built on the same removing discipline that got you to launch — applied to a product the market is now actually using.

Preorder · September 2026

What you'll take away

  • 01 How to read post-launch signal without overweighting the loudest customer.
  • 02 A framework for choosing the next thing to add — and the three things to remove first.
  • 03 How to keep the product shape coherent when usage is pulling it in five directions.

Once a product ships, the second-most-common failure mode is growing it the wrong way. Loud customers ask for features. Adjacent markets pull at the shape. The team starts adding before the product has stabilized — and the work that got the launch out the door gets buried under the work that follows it.

Grow, the third volume of the Subtract to Ship method, is a working manual for the post-launch year. It applies the same removing discipline that got you to launch — but to a product the market is now actually using.

What this book covers

  • How to read post-launch signal without overweighting the loudest three customers.
  • The “next-three-out, next-one-in” rule: a small framework for keeping the product shape coherent.
  • How to defend the original shape of the product against well-meaning growth pressure.

Who it is for

Founders and product leads in the first 12-24 months after launch. Innovation teams whose pilot has just gone to production. Anyone watching a clean product start to bloat under the weight of its own success.

Series context
