You have users. You have traction. You don't know if it will last.
After the Build is a free 8-minute brief that shows where you are and what to change.
The problem
Vibe coding solved the build problem. It exposed a different one.
The same tools that let you ship in a weekend let every competitor do the same. Early traction is real: the first signups, the DMs, the Product Hunt spike. It does not stop anyone from copying you. Most founders who shipped an AI product in the last two years are competing on the two things that are easiest to copy: model quality and features. Both wear away. Your product may be good. The question is whether what you have built gets harder to copy over time, or only lasts until something better ships.
Three situations this brief is written for
01 / 03
You have traction. You don’t have defensibility.
Early users prove people want it. They do not stop a competitor from copying it.
You know the product works. What you can’t say yet is why a team with more money couldn’t rebuild it in 90 days. This brief was written to close the gap between being sure of the product and being sure of the strategy.
02 / 03
You’re shipping features. None of them stop customers leaving.
Shipping fast does not make you hard to replace. A feature is the easiest part of a product to copy.
The upside of vibe coding is that you ship fast. The problem is that speed resets with every model release, and you have put your effort into the part that gets copied fastest. The brief shows which parts of a business get harder to copy over time.
03 / 03
You know something needs to change. You don’t have the words for it.
Your execution is fine. What is missing is a strategy, and nobody has given you one yet.
The metrics look fine. Underneath, nothing is clearly getting stronger. Working harder will not fix it. You need a check that names where you are and the one move that changes it.
What's in the brief
Six sections. Eight minutes.
01
The Defensibility Timeline
Which of the four kinds of advantage you are competing on right now, and when it is likely to stop working.
02
The Four Stress Tests
Four pass or fail questions that tell you whether you are building a business or a set of features. Most founders answer at least two wrong.
03
The Six Structural Moves
The specific changes that make a business harder to copy over time. Each comes with a decision check and a real company example.
04
Where You Actually Are
Your current stage, the one sign that you are ready to move on, and the one question that tells you the truth.
05
The One-Sentence Test
Whether you can say in one sentence why you won’t get copied, and a template for writing it if you can’t yet.
06
The Fault Line Underneath Everything
NVIDIA, ElevenLabs, Harvey AI. Why timing is the thing most founders can’t read, and how to start reading it.
Can you say in one sentence why you won’t get copied?
Section 05 of the brief tests your answer and gives you a template for writing it.
