Trustee Tier · Access program

For people who pronounce it correctly.

Trustee Tier is for the custodians, family offices, methodology stewards, allocators, and academic reviewers who use AI for work where being wrong has consequences — and need their AI platform to carry calibration receipts they can defend in front of an investment committee, a regulator, or a journalist.

Trustee Tier is a designed offering — applications are open now; the first cohort onboards with the first quarterly publication cycle.

The Trustee Compact

A reciprocal relationship, not a subscription.

Trustee Tier is structured as a compact rather than a service contract. Aequara commits to four obligations toward you. You commit to four obligations toward the methodology. The compact is what makes Trustee Tier work — a one-way subscription would not survive the discipline that calibrated measurement requires.

Aequara to Trustee

What we owe you

Methodology charter — full ~40-page document, model cards for every routed provider, mathematical appendices, hash-stable across cycles.
Brier ledger — every AI prediction, every horizon, every error, queryable by model and steward.
Named steward — a real person whose name is attached to your account; whose calibration track record is visible.
MENSURA index access — institutional crypto benchmark data with a published methodology hash, as MENSURA launches.

Trustee to Aequara

What we ask in return

Confidentiality — pre-publication model amendments and Mensura research stay sealed until the quarterly cycle.
Annual feedback letter — a single page once a year on what the platform got wrong, what calibration drifted, what to sharpen.
No issuer-aligned use — you cannot pass Trustee outputs to a rated entity or use them to train a competing model.
Public attribution — when Aequara outputs inform your published views, cite the methodology hash.

"We don't grade on a curve. We grade on a horizon. Trustee Tier is for people who recognize the difference."
Four tiers · annual

Access programs.

All tiers include the methodology charter, Brier ledger, and named steward. Differentiation is in research depth, MENSURA index access level, and human-time access. Pricing is published — Aequara does not negotiate access tiers as a discipline-preserving constraint.

Due diligence

What you should ask us before signing.

If you can't ask these questions, you shouldn't be a Trustee. If we can't answer them, we shouldn't be Aequara. We've published our answers below — verify against the methodology charter.

Q1

Where does revenue come from?

By design: 100% subscription, licensing, and Trustee Tier. 0% from rated entities — the anti-issuer-pay firewall is structural, not aspirational. Quarterly disclosure begins with the first publication cycle.

Q2

What's your live Brier score?

The NPX-100 cohort hasn't published its first cycle yet — we won't quote a number before it exists. What is live today: the AEQUARA Model Calibration Index — 18 models scored on 13,171 pairs (7,447 forecasts + 5,724 knowledge MCQs), reproducible from published checksums. Lower Brier is better.

Q3

When was the methodology hash last changed?

It hasn't been published yet. The hash locks at v1.0.0 ratification and is designed to stay stable across operational amendments — only methodology changes move it. Until the first cycle ships there is no hash history to show, and we won't invent one.

Q4

Who's the named steward on my account?

Foundation: rotating editorial steward, ≤ 12-month assignment. Mid: dedicated steward, dedicated 12-month assignment. Principal: dedicated co-stewardship pairing. Bespoke: bespoke co-stewardship arrangement. The program is designed so each steward's calibration track record is part of their bio.

Q5

What was your worst call last cycle?

No cycle has run yet, so there's no worst call to name — but each cycle's worst call will be published in the Brier ledger and the quarterly packet. We don't bury errors; we name them. Trustee Tier members receive the steward's commentary on it as part of the cycle delivery.

Q6

Can I see the auditor letter?

Not yet — no attestation cycle has run. The design commits to annual external attestation with the auditor rotated every 5 years to prevent capture; the first letter publishes after the first full year, embargoed 30 days to Trustee Tier members before public release.

Apply for access

The application is short. The review is real.

Trustee applications are reviewed by the editorial steward team. We're looking for fiduciary intent, methodology literacy, and the willingness to provide an annual feedback letter. Applications are answered within 14 days. Pricing is published. Access is not negotiated.

Application — six fields
  • 1 · Your name and the entity you represent
  • 2 · Tier requested · Foundation / Mid / Principal / Bespoke
  • 3 · Fiduciary context · whose capital, what mandate
  • 4 · How you'll use the methodology · 3-5 sentences
  • 5 · A reference · one named professional contact
  • 6 · Your pronunciation of "Aequara" · phonetic spelling
