Methodology and constitution
How the Atlas is built, verified and governed
The Atlas of the Healthspan Economy is a structured, reviewed record of the organizations, modalities and events of the healthspan economy. This page states what qualifies for the record, how each entry is verified, when it was last checked and the rules the record holds itself to.
This page covers the Atlas and its four pillars. It does not cover the research the site publishes on top of the record. A report defines its own panel, its own questions and its own scoring, so each one publishes its own method at its own address, listed below. The constitution and the commercial disclosure on this page bind the reports as well.
Where the record stands today
The Atlas of the Healthspan Economy records 389 organizations. Of those, 385 are distinct controlling organizations once subsidiaries and brands are grouped under their parent. In the last 90 days, 215 records were re-checked against their sources. Every one of these figures is computed at build time from the data, and the full breakdown lives on the data page.
Not every recorded organization is placed on a country or region page. 364 of the 389 recorded organizations are placed on a geographic page. The remaining 25 are held out for one of two reasons: 24 are a fertility or IVF clinic or a pure booking or telehealth platform, out of the Atlas's geographic scope, and 1 does not resolve to a single country. Both groups keep their own Atlas entity page. Neither appears in a country or region count.
What counts
The Atlas maps the premium healthspan economy across four categories, its pillars:
- P1 Longevity & Preventive
- P2 Femtech & Women's Health
- P3 Integrative & Functional
- P4 Healthtech & Diagnostics
An organization qualifies only if it clears two bars. First, verifiability: it is a real, named organization with an official source that confirms it exists and operates. An announcement of something not yet open is held as a watch item, not admitted. Second, scope: it delivers a health service to individuals, that is clinical care, screening, diagnostics or a structured preventive or longevity program that people attend or enroll in.
A company that only sells a product for others to use, is purely aesthetic, or is an investor, publisher, event or media property does not qualify. General practices qualify only for a specific longevity or preventive program they assert, and only that program's modalities are recorded. The full rule is governed by the Atlas policy, the single source of truth for admission, and no organization can pay to be included.
How it is verified
Every record is admitted through a source-first intake. A candidate is confirmed against an official source, classified into a pillar and its modalities and stamped with the date it was checked. That date is carried through to the entity page and shown as the record's verification date, so a date on the page is a claim about when the source was last read, never when the site was last built.
Records are re-checked on a rolling basis and the verification date is updated when they are. Facts that decay, an event that has passed, an organization that has closed, a rebrand or an acquisition, are moved on the date they are confirmed, not left to imply a currency they no longer have. Organizations that close keep their entity page, marked defunct, rather than vanishing from the record.
That is how a record is kept current. It is not the same question as what was published wrong and later put right, which is recorded separately and by date on the corrections page.
Published research is re-checked the same way, against the raw material it was drawn from rather than against a later summary. What each study checked, and what its own correction pass found, is stated in that study's method: for the 2026 report, under the 15 May correction pass.
What "recorded" means
Recorded means an organization that is published and operating. Rows still under review are held back before publication and are excluded from every public count. Organizations that are defunct or announced but not yet open keep their entity page but are not counted among the recorded organizations.
The recorded count and the distinct-parent count are different figures that measure different things. The recorded count counts every recorded organization, a parent and its subsidiary as two, because each delivers its own services. The distinct-parent count groups subsidiaries and brands under their controlling organization, so it answers how many independent organizations the field has rather than how many records the Atlas holds. Both are shown on the data page, side by side.
The constitution
What the Atlas will never do:
- Never accept money from a listed organization.
- Never sell placement.
- Never rank by opinion.
- Never publish a claim without a date and a source.
- Disclose every commercial relationship, including GKZ Labs.
The Sandria disclosure
Healthspan Economy is published by Sandria OÜ, an Estonian company registered in Tallinn under registry code 17585074. Sandria is a measurement organization. It builds and publishes this record and it sells nothing. Commercial services sit in a separate company, GKZ Labs, and they have no influence on what the Atlas records, how it classifies an organization or how any measurement scores. The relationship is disclosed here, permanently.
Operators listed in the Atlas may correct facts about themselves; they cannot influence how they are ranked, classified or described. A correction made to published work is recorded and dated on the corrections page.
Healthspan Economy takes no payment from the organizations it records. Inclusion, exclusion and placement are never affected by any commercial relationship. No organization has ever paid, directly or indirectly, to be listed here or to be described in any particular way.
