Industry categorization has been one of the most common feature requests since we launched Store Leads. Today, we're launching Categories which groups stores based on the products they sell.
Our category list is hierarchical and consists of almost 400 separate categories. Here's our new Category filter showing a subset of our top-level categories.
Just click on a category to filter the results to stores that belong to the desired category. You'll then see a list of sub-categories (if any) so that you can refine your results even further.
Category information has also been added to the Store Leads API.
Note that the Category Filter is only available on paid plans.
