How it works

From crawl to classification.

Every week, Kleovo crawls live app-ads.txt and sellers.json files, cross-references them against live app store data, and classifies every supply path.

The platform

Three modules live. Web and CTV next.

Every module draws from the same verified dataset, updated weekly across 270K store-verified apps and 20,448 publisher domains.

Live

Coverage Verification

MATCH, CONFLICT, or MISSING per publisher, per SSP line, against live sellers.json. Know exactly where your declarations hold and where they break.

Live

Seller Intelligence

Classify every seller_id as TRUE_DIRECT, UNIQUE_RESELLER, or EXCHANGE_RESELLER. Know the full supply path, not just the declared line.

Live

SPO Intelligence

Validate sellers.json hygiene, surface relationship mismatches, and get per-SSP-line breakdowns with publisher reach data.

Coming soon

Web Intelligence

The same verification framework extended to web publishers, matching the depth already live for in-app.

Coming soon

CTV Intelligence

Seller classification, coverage status, and relationship validation across connected TV supply chains.

Why Kleovo

Not another ads.txt monitor.

Most tools tell you a line is missing. Kleovo tells you what the mismatch actually means, whether the seller is authorized, and what the relationship classification is across both sides of the supply chain.

Publishers are verified against live Google Play and App Store listings. No web domains. No parked sites. Only publishers actually serving in-app inventory.

Store-verified apps only

Every domain mapped to a live app store listing. No unverified sources.

Weekly crawl across 270K apps

app-ads.txt and sellers.json refreshed every week. Changes surface when they happen.

IAB-aligned classification

Every seller_id classified per spec: PUBLISHER, INTERMEDIARY, or BOTH.

Conflict detection

Duplicate seller_ids and relationship mismatches surfaced automatically.

Full supply path visibility

TRUE_DIRECT, UNIQUE_RESELLER, EXCHANGE_RESELLER, and MISSING. Broken down per publisher, per SSP line.

Who it's for

Built for every team in the supply chain.

Whether you sell inventory, buy it, or audit it for clients, Kleovo gives you the verification layer you are missing.

SSP

Verify your publisher base.

Check whether publishers are declaring your seller_id correctly in their app-ads.txt. Confirm relationships in your sellers.json match what publishers claim. Find out before your DSP partners do.
