# Your market. Defined.

Size a Shopify audience by premium theme and Apple Pay registration country. Explore real aggregate counts and prepare a focused SignalTally market brief.

Define the merchants your product fits. See the size of the opportunity, inspect the evidence and take a specific audience into your next conversation.

## Start with product fit

Choose a theme your product or service supports. Narrow the audience with Apple Pay evidence and registration country. A shared setup creates a research starting point, not a guaranteed buyer.

## Size before you commit

Every count is computed from the dated Shopify snapshot. The public builder exposes selected aggregate views; individual records and broader access remain subject to a paid scope.

## Carry the scope forward

Copy a market brief, share a view or take the selected audience into an evaluation. Define the fields, volume and evidence-age requirements before activation.

## Default market view

445,292 premium-theme domains with Apple Pay detected. Observed 2026-09-12. The browser can select seven theme views, eight country views and two payment states from a fixed aggregate extract. No individual records are returned by this builder.

Counts are distinct normalized domains observed on 12 September 2026, not distinct companies or measured revenue. The builder covers paid theme catalogue matches only. Theme matching uses the detected schema name, ignoring letter case. Country means Apple Pay registration when Apple Pay is detected; it is not headquarters, shopper location or a traffic distribution. All markets includes records with an unknown registration country. The view is a fixed aggregate extract, not a live search of the private database.
