About
Origins and purpose
The Assay Foundation is a new institution with an old form. Its credibility comes from how it is structured, not from a history it does not yet have. This is the honest account of where it came from and what it is for.
The IDEA Methodology was developed in enterprise procurement, where the problem it addresses is felt most sharply: organisations buy AI implementation work with no independent way to know whether it was done well. It was built and refined against real engagements before it was anything as formal as a standard.
The methodology was contributed to the Foundation by OAI Limited, the firm that developed it. The Assay Foundation was then established as an independent body to steward it — limited by guarantee, with an asset lock and a weighted board — so that the standard would be held in the public interest rather than owned as a commercial asset. The founder arrangement is disclosed in full on the independence page.
The Foundation exists to make AI implementation work legible to the people who buy and audit it. It tests Engagements against a published standard, applies a Hallmark to those that pass, and records them on a public Register that anyone can verify against. The aim is concrete: that "Is it Hallmarked?" becomes a question a procurement officer can ask and cite.
It does this without competing with the people it certifies. The Foundation does not deliver implementation work, engage Practitioners, or perform an Assay itself. It stewards the standard, accredits independent Assayers, and keeps the Register. Its only product is the integrity of the mark.
The Foundation borrows the form of the assay office and the hallmark — the system by which British silver has been tested and marked since 1300 — because the problem is the same one: how a buyer can trust the quality of something they cannot easily test themselves. The vocabulary of Assay, Hallmark, Touchstone, and Date Letter is taken from that tradition deliberately, and is explained, not used as decoration.
The borrowing is open. The Foundation does not claim a centuries-old lineage; it claims a well-tested structure. It was established in 2026 and makes no pretence of age or scale beyond what is true. The heritage is in the design of the institution, not in a fabricated past.
