UndertowIQ · The end of the monopoly

The Open Book.

The most valuable number in radio costs a fortune and takes weeks. We call it for free, from public data, and seal it before Nielsen publishes theirs — so no one can ever say we cheated. When their book drops, our call scores itself. This isn't a critique of the ratings. It's a working replacement, proving itself in the open, one book at a time.

01 · CALL

Predict the book

From the public topline history, forecast every station's next 6+ AQH share — the number Nielsen sells.

02 · SEAL

Hash it, timestamp it

SHA-256 over every call. Publish the seal before their book drops. The hash proves the calls existed first.

03 · SCORE

Let reality grade it

When the book lands, each call scores itself against the real number — our accuracy and their divergence, permanent.

Called it — head to head, on the record

No books have dropped since our first sealed calls yet. The moment Nielsen publishes, every call above grades itself here — the free number vs. the paid one, side by side.

The seal ledger

Every batch of calls we've ever sealed, newest first. Each hash is a pre-registration — proof the predictions existed at that timestamp, unchangeable after the fact.

The forecast is a plain, bounded model on public Nielsen toplines; the seals are SHA-256 commitments; the scoring is against Nielsen's own later numbers. No paywall touched, nothing hidden — the opposite of a black box. the census book · the fine print · who owns the ears.
