A proof of concept answers "can it work?". A proof of value answers "does it move the business?". The distinction matters to buyers who have seen technology work in a demo but fail to deliver in practice.
A proof of value is run on a genuine problem, with a defined outcome and a deadline. Success is judged by the result achieved, not by a feature checklist. It de-risks the decision for both sides.
For enterprises, it turns a purchase into an evidence-based choice. For providers, it earns trust by showing value rather than claiming it.
