Less guessing.
More building.

Build an enquiry assistant you can actually run. Six lessons, full source, and focused repairs for the things AI-generated apps tend to get wrong.

A sprint ends with something useful

03Build / no-build decision

The sprint contract

Less theatre. More evidence.

A focused build should answer a decision, not create another artifact for the roadmap. The work is scoped around the smallest useful surface that can produce signal.

01 / FRAME

Choose one sharp question.

Who is this for? What must the workflow prove? What is the smallest credible test?

02 / SHIP

Put the surface in someone’s hands.

Prototype the actual interaction, not a presentation of what the interaction might be.

03 / DECIDE

Leave with a useful no—or a next build.

Buyer pull, operator feedback, and product evidence become the next-step decision.

ENTRY-01
Entry 01 Receipts. The literal kind. 2 closed / verified

Most product ideas die between the deck and the roadmap. Mine get a verdict.

Every idea that crosses this bench ends one of four ways: kill it, refine it, pilot it, or productize it. Two made it all the way to the exit column. The rest of the book is open and running — that's what the ledger below is for.

the receipt prints once. everything on it is real.

Entry 03 Hire the lab. Work with the operator. 3 protocols

The same bench, applied to your problem.

Agencies have client opportunities they cannot productize. SaaS teams have ideas stuck behind engineering priorities. Operators know where the workflow breaks. I frame the problem, build a focused surface, test the signal, and hand back a next-step decision.
