See the customer signals investors might otherwise miss.

The data vendor that grades its own calls — in public

ReviewSignal turns public customer reviews into chain-level experience drivers — service, value, speed, cleanliness — for 79 consumer chains. Every pre-registered read is graded after the fact, and the misses stay published next to the hits.

The Shake Shack call, exactly as it happened

Before Shake Shack’s Q2 print, we pre-registered the read on a hashed, timestamped public ledger — with the grading rule written down in advance: a HIT required at least four of the six customer-experience aspects we track to still sit below their 210-day baselines when we re-ran the computation on grading day.

On grading day, our own collection rotation had left the Shake Shack sample 18 days stale — and on that stale sample the forecast would have scored a HIT. Instead we re-scraped 45 locations and roughly 2,000 fresh reviews hours before grading. The fuller data showed only three of six below baseline. That’s a MISS, and that’s what we published.

Why show you a miss? Because a track record you can audit beats a highlight reel you can't. Every entry on the ledger is hashed before the event and archived — you can go and verify the Shake Shack call yourself.
