The gap between an impressive AI demo and a working production system is rarely about the model. It is about data, ownership, and integration.

Most organisations have seen it by now. A pilot gets built in a few weeks. The demo is impressive. Leadership is enthusiastic. And six months later, nobody is using it.
The instinct is to blame the technology. In our experience, the model is almost never the problem. The pilot fails to become a system for much more ordinary reasons.
A pilot gets a curated sample: well-formatted documents, complete records, the happy path. Production gets scanned faxes, half-filled fields, duplicates, and the one supplier who formats everything differently. If the messy cases are not in scope from day one, the pilot is measuring a business that does not exist.
A pilot sits beside the operation. A production system changes it. Someone's job now includes reviewing a queue, handling exceptions, and trusting an output they did not produce. If no one owns that change - with the authority to redesign the process around it - the system stays a demo, politely ignored.
Demos optimise for wow. Systems need a definition of done: what accuracy is acceptable, on which cases, measured how, and what happens when the system is wrong. If those questions are answered after the build, the answer is usually “not good enough” - discovered at the worst possible moment.
The unglamorous majority of the work is connecting the system to the tools the business already runs on - reading from them reliably, writing back safely, handling authentication, retries, and failures. Pilots skip this. Production is mostly this.
A demonstration is not the goal. A system that holds up against real users, real workloads, and real failure modes is. Production capability matters more than impressive prototypes.
