Short Answer
Which is better, Hirebase or TheirStack?
Pick TheirStack if you prospect by technology stack and want its webhooks, MCP server and no-code integrations today. Pick Hirebase if you need the jobs themselves: from employers' career pages and ATS first rather than Indeed and LinkedIn, TheirStack's two largest sources; live within 1–2 hours and removed every hour; and cheaper at every volume TheirStack publishes above its $49 plan. Two million jobs a month cost $999 on Hirebase and $2,300 on TheirStack.

- Webhooks for new and closed jobs, an MCP server and Claude and ChatGPT connectors.

Each point links to the page it comes from, checked October 21, 2026.
A spot check: 69 jobs against 5
On October 21, 2026, TheirStack's app listed 69 open jobs for Topaz Labs (job closed: no; posted in the last 2 years), including roles that are no longer open and one role listed twice. Topaz Labs' own Lever board listed 5. TheirStack also showed June 2026 posted dates for roles Lever says were created in March. One example, not a statistic.
Source: api.lever.co/v0/postings/topazlabs?mode=jsonA null closed_at can mean “we don’t know yet”
Its webhook docs say a null closed_at “means the job is still considered open (or we don’t know yet)”.
Source: theirstack.com/docs/webhooks/event-type/webhook_job_closedIndeed and LinkedIn are its largest sources
Its sources page lists indeed.com with 150M jobs (39.87%) and linkedin.com with 72M (19.11%). A job can carry several sources.
Source: theirstack.com/en/docs/data/job/sourcesRepeat fetches and webhooks are charged
“Repeated requests for the same data will consume credits each time”, and a webhook event costs the same as an API record: 1 credit per job.
Source: theirstack.com/en/docs/pricing/credits“Mode” at H&M
Its technology page lists 90,026 companies using Mode, the BI tool, led by Deichmann, H&M and KIABI at “High confidence”. In German and French job ads, “Mode” means fashion.

Its Drift page lists 49,341 companies, led by Forsvaret, Københavns Kommune and Oslo kommune. In Danish and Norwegian, “drift” means operations.
Source: theirstack.com/en/technology/driftQuestions to ask TheirStack before you buy
- How many of your jobs are active today, rather than collected since launch?
- For my target companies, what share of jobs come from Indeed or LinkedIn rather than the employer's own page?
- How do you decide a job has closed, and how often is it re-checked?
- How many distinct job mentions does a technology detection need, and can I see the evidence?
Quality By Design
Why Hirebase skips job-board-only jobs.
We deliberately don't index jobs that exist only on job boards. Listings reposted across Indeed, Glassdoor, Adzuna, Monster and the rest are where stale, agency and duplicate jobs pile up. Providers that index boards have to decide when a job that appears in many places has really closed. Here is how three of them describe it in their own docs.
Coresignal: active until every copy expires
Its data dictionary marks a job expired only when all of its related records, across every source, have expired.
Source: docs.coresignal.com/jobs-data/multi-source-jobs-data/dictionary-multi-source-jobs-dataTechmap: duplicates kept, never re-checked
Its FAQ says duplicates are kept and flagged, postings are not re-checked for removal after collection, and a job is assumed active until its validThrough date or 30 days after it was created.
Source: jobdatafeeds.com/faqTheirStack: Indeed and LinkedIn first
Its sources page lists indeed.com (39.87%) and linkedin.com (19.11%) as its largest sources, and its webhook docs say a null closed_at “means the job is still considered open (or we don’t know yet)”.

When TheirStack is the better pick.
- You sell to companies by the software they use and need company technology profiles today, with buying-intent topics.
