Now you can filter companies by when you revealed them

If you run weekly or monthly lead pulls in TheirStack — revealing companies in batches and pushing them to Apollo, a CRM, or a spreadsheet — you've probably wanted to go back and ask "give me the companies I revealed between these two dates" without rerunning the original search.

You can now. There's a new Company Reveal state filter on both company search and job search. It gives you three choices: keep only companies you've never revealed, keep only ones you've revealed at some point, or pick Revealed between dates to narrow to the ones you revealed inside a window you choose.

In the API, this maps to two new filters on /v1/companies/search and /v1/jobs/search:

  • company_revealed_at_gte — only include companies you revealed at or after this timestamp
  • company_revealed_at_lte — only include companies you revealed at or before this timestamp

Both are team-scoped — they use the reveal history of the calling team, so the filter only narrows to companies you've actually revealed.

Why we built this

A few customers told us they run the same search week after week with the reveal filter set to exclude companies they'd already seen, export the result, and push it to Apollo. The catch: as soon as you scroll through the results table and click into companies, those get marked as revealed, so by the time you hit Export the filter has shrunk what comes back. The export ends up empty or near-empty.

With this filter, the workflow becomes:

  1. Do your pull however you like — search, browse, reveal.
  2. When you want to act on that batch, search again with Company Reveal state → Revealed between dates set to the window of that pull (e.g. last 7 days).
  3. Add the results to a list, or export them straight to CSV / push to Apollo.

The "revealed in the last week" set is now something you can ask for directly, instead of reconstructing it by holding the results page open and hoping nothing scrolls.

What you need to do

Nothing. The filter is live in the app under the Company group, and the two API fields are documented in the company search and job search references.
