Did your podcast ad actually run as contracted?
Meyppi checks published media itself: whether your creative appeared, in which version, at what timestamp, and for how long. Not what the publisher reports. What actually aired.
Nobody independently confirms delivery.
You paid for 240 placements.
The publisher reports 240. Your spreadsheet says 240. The invoice is for 240. And not one of those numbers came from anyone whose job was to check.
You don't know what actually aired.
A 24-second cut instead of 30. Version 2 instead of version 1. An episode that quietly dropped out of the feed. Self-reported data cannot see any of this, because it is the thing being reported on.
You can't prove it either way.
When something feels wrong, the conversation stalls at "our report says it ran." Without independent evidence there is no reconciliation, no makegood, and nothing to show your client.
From expected delivery to defensible evidence.
- 01
Expected delivery
You give us the contract side: every creative version, the publishers, the episodes, the flight dates.
- 02
Independently observed
We pull the published media from RSS feeds and other permitted sources, then fingerprint each episode end to end.
- 03
Discrepancy detected
A 24-second cut where 30 seconds were bought. Version 2 where version 1 was contracted. Nothing aired at all.

Evidence produced
Each finding ships with its evidence: hashes, offsets, match counts, timestamps. You can re-check any of it.
A discrepancy report you can put in front of a client.
A report, delivered as PDF and data exports: every placement classified, every classification backed by evidence you can open and inspect.

Three deliverables per audit.
Verification report
Placement-by-placement status for the whole campaign, delivered as a PDF plus CSV and JSON exports.
Evidence chain
Creative ID, version, file hash, match offset, covered duration, confidence. Retained for every single result.
Exception review
Where the evidence is ambiguous, a person looks at it and says so in the report. Ambiguity is reported and explained.
Built for media buyers.
For agencies
Your name is on the client report. Meyppi gives you placement-level numbers produced outside your own reporting stack, which is what makes them useful when a placement is disputed.
How agencies work with usFor brands
You approve the plan and you pay the invoice. Verification that starts from the published media tells you what ran, regardless of what anyone's report says.
How brands work with usMeyppi verifies pre-produced audio creatives in podcast and digital audio content where the published media is independently observable. We do not claim legal proof. Every result comes back classified as Detected, Not Detected, Insufficient Signal, or Manual Review Required. If we cannot see the media, we do not guess.
Give us one completed campaign.
We'll tell you exactly what ran, and back every line of it.
