Custom AI Products
Custom Tool Prototype
A working proof of concept covering one complete use case, delivered with a structured PRD and a precise master build prompt so the idea can be evaluated on evidence rather than opinion.
A prototype is a decision-making instrument. It exists so you can test a real workflow, show it to real people, and decide whether a production build is justified, before a production budget is committed.
