From firehose to signal: how we rank what actually matters

By Grapevine Team

Legacy media monitoring was built for a slower world: daily clip reports, endless feeds, and dashboards that told you what happened but never what mattered. The result is a firehose — and a firehose is useless when reputations are made and unmade in hours.

Volume is a vanity metric

A spike in mentions tells you almost nothing on its own. Ten thousand reshares of a meme matter less than a single sentence in a story that's about to be picked up by every outlet in the country. So we stopped counting and started weighing.

The narrative score

Every mention is scored on reach, sentiment and momentum. Reach captures the audience behind a source. Sentiment captures tone and intensity, not just positive or negative. Momentum captures whether a story is accelerating — the derivative matters more than the level.

We'd rather show you ten things that matter than ten thousand that don't.

Combined, these let us rank the entire conversation and surface the one story you need to know first — with the context for why it's rising. That's the difference between drinking from a firehose and a trusted colleague tapping you on the shoulder.

First to know. First to move.

Your first topic takes two minutes. The mentions start landing right away.
