The Proven Improvement Evaluation (PIE) methodology that Provers apply is licensed from Earth Returns. That licence is the whole of the relationship.
Certified Provers are granted the right to apply the PIE methodology in their work. The Institute trains them in it, examines them on it, and upholds the conduct around it. Beyond that licence, the two organisations are separate.
We state this relationship rather than understate it. A body whose product is trust cannot afford an unexplained connection; it can afford a clearly-bounded one.
The terms "PIE", "KiniCo", "KiniAurum" and related marks belong to Earth Returns and are used here only to describe the methodology Provers are licensed to apply. The Institute's certification of a Prover is independent of any commercial use that Earth Returns or any Improver makes of a verified outcome.
