Research & sources

Know what the
numbers describe.

We use primary industry research to frame questions, not to promise results. Definitions, geography and dates matter.

Figures on this website describe different populations and revenue categories. Participation counts do not equal customers; industry forecasts do not predict an individual business’s performance. Our strategic implications are analysis, separate from the original findings.
