Brand attributes
What we stand for
Six principles that shape every publication, every dashboard, every decision.
Rigour
Every data point is traceable. Every analysis cites source and date. We'd rather say we don't know than estimate without method.
Clarity
Technical language without defensive jargon. Visual hierarchy that leads to the conclusion in seconds.
Independence
No producer, trader or institution shapes our conclusions. The methodology is always published.
Global perspective
World analysis before national analysis - even when the client is Portuguese.
Utility
We publish to decide, not to impress. Finish serves reading.
Structured openness
Freemium access, transparent methodology, shared code and data whenever possible.
How we communicate
Precise. Informed. Measured.
KEYSTONE. reads like a modern institution - the sobriety of a central bank report with the contemporaneity of a technology publication.
“Portuguese marble block exports contracted 5.3% in 2023 vs 2022, reflecting mainly the slowdown in Chinese demand.”
“Fantastic year for Portuguese marble! Everything booming and the best is yet to come.”

FAQ
Plain answers, institutional posture.
Can I cite KEYSTONE. in my own publications?
Open: non-commercial citation only. Data: no citation rights — internal reading only. Professional: single-user, non-commercial citation rights across the full catalogue. Per-publication purchase: single-user licence with commercial citation in the buyer's deliverables. Every figure carries a traceable source line.
Why should I trust reconciled figures over the raw sources?
We don't replace raw sources - we expose the seams between them. When UN Comtrade and Eurostat disagree on a bilateral flow, both series remain visible and our bridge is documented.
How often do indicators update?
Monthly for trade data. Annually for annual-series dashboards and existing outlooks, with new outlooks released as they are completed. Every dataset carries a "last updated" stamp matching its source release date.
Do you cover minerals beyond natural stone?
Yes - from industrial minerals (feldspars, limestones, clays, metals…) to ornamental stone. Natural stone is the specialisation with deepest producer-level resolution.
Can I cancel or downgrade at any time?
Yes. Data and Professional billing stops at the next cycle; already-downloaded studies remain accessible offline.
Can I try KEYSTONE. before subscribing?
The Open plan is permanent and free — it includes the world-stone and world-mineral export dashboards plus the UK Macroeconomic Outlook 2026–2030 as a full-text sample. Upgrade to Data for the full dashboard library, or to Professional when the data starts driving decisions.
