Vibe coding for CPOs: from a spec that describes the product to a build that is the product.

Product leaders spend their careers describing software for other people to build. Vibe coding collapses that. The prototype that used to be a Figma file and a document is now a working app you can put in front of a customer. Discovery gets faster, arguments get settled with evidence, and the spec becomes the thing itself.

ROUND 01 — The CPO seat

Why a CPO’s build is different.

The trap is that a CPO's prototype is unusually convincing. It looks like the product, it works like the product, and it gets sold like the product. Engineering inherits it as a 'starting point' that was never built to be one, with decisions baked in that were only meant to test an idea.

This page is about vibe coding from the product seat: what it takes off your week, how a prototype turns into technical debt, and how to keep discovery fast without handing engineering a mess.

ROUND 02 — What it buys you

The manual work a CPO stops doing by hand.

  • 01The month between the idea and the evidence

    Something real and data backed in front of five customers this week, instead of a mockup they have to imagine using. Discovery stops queueing behind engineering capacity and the roadmap argument gets an answer.

  • 02The usage question you file a ticket to ask

    Funnels, retention, feedback and interview notes in one place, from the product database and the support tool, shaped the way you think about the product. You stop waiting a week to learn what a release did.

  • 03The spec that gets read three different ways

    What you mean, shown as something that runs rather than described in a document. Engineering starts from a working reference, and the rework that came out of misreading a page stops happening.

  • 04The status you collect for the leadership meeting

    Six teams asked by hand every week, replaced by a page that fills itself. The prep hours go back into the part of the job that is deciding what the company will not do.

ROUND 03 — What breaks

Where it goes wrong for a CPO.

  • The prototype is sold as the product

    Sales saw the demo. A customer signed. Now the exploratory build with no error handling and no tests has a contract attached, and 'we will rebuild it properly' has no date.

  • Engineering inherits decisions nobody made

    The data model, the auth approach and the third-party services were whatever the AI picked first. They are now load-bearing, and changing them costs more than the original build.

  • Customer data in the prototype

    To make the test realistic you loaded real accounts. The prototype is on a personal hosting account with no access control, and it is a copy of production customer data.

  • The beta has no way back

    You shipped the feature to real users. It has a bug. There is no rollback, no feature flag and no backup of what the data looked like before.

ROUND 04 — With a CTO in your corner

What changes.

A CTO in your corner draws the line between discovery and production, and helps you cross it on purpose. Prototypes stay cheap and disposable. The ones that are going to live get the ten things production needs before a customer touches them. When engineering takes over, it comes with a written account of what was decided and why. Discovery stays fast. The handover stops hurting.
