How company search in your product works
TheirStack runs the company search inside your product: your users filter companies by the roles they hire, the technologies they run, size and industry, and see how many companies match as they refine the search.
Search
Map your search filters to ours
TheirStack takes your users' filters on roles, technologies, size, industry and funding in one Company Search API call, so your search box needs no data of its own.
- Company search with job filters
- Size, industry and funding filters
- Technology pickers from our catalog
Count
Show how many companies match as filters change
TheirStack returns how many companies match as your users change filters, so they size the market and refine the search before building a list.

- Market size before a list is built
- Narrow by size, country and industry
