How Tehran Index works.

Tehran Index follows developments across Iran's technology and business ecosystem from a curated set of publicly accessible sources: Persian-language technology publications, company-owned channels, regulatory announcements, official registry and gazette records, financial disclosures where available, and verified English-language coverage. Source selection is based on reliability, consistency, and verifiability. We do not publish information sourced from anonymous claims or unverifiable insider accounts. Published records name the authoritative source; the specific access channels and archives the desk uses are documented internally and available to research partners on request.

Coverage spans Persian (Farsi) and English sources. Persian-language sources are the primary input for Iran market developments — English-language coverage is used for international context and cross-referencing. All published output is in English. We do not mix Persian and English within published headlines or summaries.

Every published signal, company profile field, and market claim is reviewed against at least one publicly accessible source. We do not publish: estimated funding amounts without a source, founding team information without verification, company names without checking against official websites, or numbers that cannot be traced to original reporting. If we are uncertain, we mark the field as unverified rather than omitting or fabricating it.

Nothing is published automatically. Each candidate passes deterministic relevance and misinformation filters, an extraction step, and an automated audit that flags calendar, currency, entity, and unsupported-fact errors — and is then approved by a person before it goes live. Machine assistance widens coverage; a human makes the publish decision.

Each signal and company carries a verification tier. Verified: confirmed by an official source or multiple independent sources. Corroborated: multiple sources in agreement. Reported: a single sourced report, labelled as such so it is never mistaken for greater certainty than it carries. Items are source-linked; where a fact cannot be sourced, we omit it rather than guess.

Monetary figures are published in the currency the source uses, Iranian toman or rial. Where we add a USD equivalent, the conversion is ours: it uses a documented free-market exchange rate and is labelled with the rate and the period it applies to. Historical flows are converted at the rate of their period, never today's. Official exchange rates are not used; they do not reflect market reality.

Tehran Index covers the commercial innovation economy: companies, technology markets, business regulation where directly material to covered companies, and the macroeconomic context needed to interpret company figures. We do not publish political analysis, security coverage, or sanctions guidance. For sanctions-sensitive entities, we use official designations and public regulatory language only. We do not speculate on sanctions exposure or provide compliance advice.

Company profiles and sector data are updated as new verified information becomes available. Signals are timestamped and not edited after publication, except to correct factual errors — which are noted explicitly. We welcome corrections at desk@tehranindex.com.

Analysis is always visually separated from sourced fact — every interpretive line is tagged TI VIEW — and carries its own calibration, distinct from the evidence verification tiers above. High confidence: multiple independent evidence lines point the same way. Medium confidence: a defensible reading of limited or single-line evidence. Emerging signal: an early pattern worth monitoring, not a conclusion. Where desk research contradicts a live corporate source, we may publish a research determination — always labelled as such, with the disagreeing source and its retrieval date shown on the record; where the evidence is materially incomplete, the record carries a conflicting-evidence state instead of a determination.
