Farmers are asked to make decisions in a market full of claims.

Some claims are supported by good evidence. Some are not. A lot of useful evidence never becomes public, structured or comparable.

Proof exists to change that. We want field evidence to survive the season, stay connected to its context, and become useful to the people who need it.

Make evidence accessible to every farmer globally.

Building records that can be inspected, compared and trusted over time. Protecting the farms and people who contribute the evidence.

The public should be able to see what happened. The farm should not have to expose everything to make that possible.

Five precepts that shape how Proof operates.

    Precepts of the record layerv1
  1. I
    Records before rhetoric
    Proof shows records, not slogans.
  2. II
    Context before conclusion
    Every outcome needs crop, soil, season, treatment, control and evidence.
  3. III
    Neutrality before promotion
    Proof does not sell rankings, paid placement or product endorsements.
  4. IV
    Privacy by design
    Farm identity and raw evidence are protected.
  5. V
    Failed results stay
    A serious evidence base keeps the results that did not work.
    6. Five precepts · applied equallyTo all contributor classes

Proof starts with biologicals because the need is urgent.

There are claims, scepticism, mixed results and a real need for comparable field evidence. Biologicals are where the evidence gap is widest. The architecture is built to expand.

  1. [01]
    LaunchCurrent
    Biological and biostimulant trials in arable systems.
  2. [02]
    Near term
    More categories of arable evidence — nutrition, biostimulants, varieties, agronomy practice.
  3. [03]
    Long term
    Other farming systems — horticulture, livestock, perennial crops.
  4. [04]
    Ambition
    Every farmer, anywhere, able to see what was tried and how strong the evidence is.

A farmer, anywhere in the world, should be able to see what was tried, where it was tried broadly, what happened, and how strong the evidence is.

In the future, Proof intends to create the Proof Foundation.

The Foundation will use a portion of Proof's profits for public-good work in agriculture. Its purpose will be to help farmers make better decisions, support open evidence standards, and ensure that useful knowledge does not stay locked away from the people who need it most.

The non-negotiable

Proof will not sell sponsorship as influence.

The record must come first.

The Proof Foundation does not exist as a legal entity today. It is stated here as future intent, requiring proper governance and Proof's commercial success before launch. No specific percentages are committed; no legal undertakings are made on this page.

The record starts with contributors.

Proof is opening first to people who already create field evidence and want it to last.
