How do I track a company's hiring over time?

TheirStack lets you track a company's hiring over time by pulling every job it has posted and counting them by month and team. In the Job Search API, filter by company domain and a posted-date range. History goes back to 2021 and closed jobs stay in the data, so you can compare quarters across years.

Is there an API for hiring trends data?

Yes, the TheirStack Job Search API returns hiring trends data: each posting comes with the date it went live, the date we found it, the date it closed, its location and its seniority. Result counts are free, so you can measure how many jobs a company posted in each period before paying for records.

What can a company's job postings tell me about its plans?

A company's job posts show where it is putting money next: a new team or title points to a new bet, postings in a new country point to expansion, and a sudden stop points to a freeze. In TheirStack, watch how the titles, locations and technologies in its jobs change month to month.

Can I monitor a fixed list of companies and get alerts when their hiring changes?

Yes, TheirStack can monitor a fixed list of companies: put them in a company list and use that list as a filter in a saved search. You then get daily or weekly email alerts, or a webhook that sends each new job and each closed job as soon as we find it.

Does job posting data show every hire a company makes?

Job posting data shows every role a company publishes on a job board, ATS or careers page, and TheirStack merges a role posted on several boards into one job. Read the change in a company's own trend over time, which matters more than a single total. Roles filled through referrals or internal moves don't appear.

How tracking a company's hiring trends works

TheirStack reads where a company is heading from how its hiring changes: watch a fixed list of companies, count their jobs by quarter and team, and read each change as a sign of expansion, a new bet, a freeze or a layoff.
