Can Claude Build Your Business Software in a Day?

Description and use

Claude built a functional business app in a day using Hubleto, with minor bugs fixed through iterative prompts.

Problem

Can an AI model like Claude generate a functional business application in a single day without manual coding?

Outcome

Claude produced a near‑complete business application in one day, with only minor UI and integration bugs, demonstrating that AI can accelerate low‑complexity SaaS development.

Workflow

• 1. Install Hubleto and review its built‑in apps.
• 2. Define the client’s requirements (training sessions, workers, orders, certificates, surveys).
• 3. Prompt Claude Opus 5 to plan the features.
• 4. Prompt Claude Sonnet 5 to generate code based on the plan.
• 5. Test the generated app, identify bugs, and iterate with new prompts.
• 6. Verify all functional areas (certificates, invoicing, surveys) are operational.
• 7. Deploy the final application and document remaining issues.

Evidence

Claude correctly identified that it needed four custom apps: Certificates, Questionnaires, Trainings and Workers.

Source

The software Claude built covered everything that was commissioned: a clear overview of questionnaire answers, a list of workers, trainings, certificates, orders, and surveys.
