Industry data, sized and sourced.
Verified universe counts, market-size stats, and chain-concentration breakdowns for the verticals B2B vendors actually prospect into. Updated as Orbital's data refreshes, not as annual industry reports drop.
Trade-association PDFs print one number a year. Vendors pricing into these markets need the count this week, the chain share that moved last quarter, and a credible state breakdown they can paste into a board deck. Sixteen pages, one shape: the headline number, the source, and the operator math behind it.

You're on the sizing side of the data.
Once a market is sized, the next question is who to email. The conversion side of the family lives at /data/email-lists/, with operator lists by vertical, by role, and by company size.
Everything else on this site sits under /data/. Same shape, different question: how many, how big, and how to reach them.
