Is Your AI-Built Prototype Ready for Paying Customers?
A convincing demo shows that an idea can work. A launch review asks whether a real customer can use it, whether the business can operate it, and what happens when something goes wrong.
Follow one complete customer journey
Choose the main thing a customer needs to do. Create a fresh account, complete the workflow, sign out, sign back in, and check that the right information remains. Review the same record from the operator’s account. A polished screen is useful only when the process behind it works.
Use a controlled test environment and test data for the review. List every step that still depends on a developer editing a database, a hard-coded record, or a manual action that the intended user cannot perform. Each dependency needs to be resolved or deliberately included in the operating plan.
Check access beyond the visible interface
Being signed in and having permission are different questions. A customer should see the records intended for that customer; an operator should have only the access their job requires. Hiding a button does not establish that the underlying request is protected.
A qualified developer should review the authorization rules and test requests with the wrong role or account. OWASP’s authorization guidance recommends checking permissions on every request. Keep secrets and private records out of browser-visible code and public examples.
Treat payments and notifications as workflows
If the product takes payments, review success, failure, cancellation, and the state the business actually records. The confirmation screen and the payment provider’s event are different parts of the flow. With Stripe, for example, webhook events let the app respond to payment and subscription changes.
Use the provider’s test environment to verify the configured behavior without charging customers or sending production messages. Check whether the operator can tell what happened, whether a failed action can be retried safely, and whether the customer receives the intended information.
Plan for the ordinary problems of launch day
Try the core process on a phone, with missing fields, invalid inputs, and an interrupted connection. Check that errors explain what the user can do next. Confirm who will see application errors, where operational records live, and who has the access needed to investigate a problem.
Deployment needs its own review: production configuration, the live domain, required services, backups appropriate to the product, and a recovery plan. A checklist helps organize this work; it does not replace a technical review or establish that an application is secure.
Agree on what is worth keeping
Finishing an AI-built app does not automatically mean rebuilding everything. Useful screens, workflows, and code can remain when they fit the production design. Fragile or incomplete parts may need to change. The review should explain that decision in terms of the product’s requirements.
At CodexDeus, prototype completion fits the same focused software engagement when the remaining work can be defined as one product. Send the existing app, the intended users, the most important workflow, and the launch blockers. We agree on the scope before the build begins.
