# TheirStack

> TheirStack sells [job posting](https://theirstack.com/en/docs/data/job.md), [technographic](https://theirstack.com/en/docs/data/technographic.md) and [buying intent](https://theirstack.com/en/docs/data/buying-intent.md) data built from [259M job postings](https://theirstack.com/en/docs/data/job/statistics.md) collected from [367k sources](https://theirstack.com/en/docs/data/job/sources.md) in 195 countries. It shows which companies are hiring for what, which of 33k technologies [13M companies](https://theirstack.com/en/docs/data/company.md) use, and what they are getting ready to buy. The data is available in a [web app](https://theirstack.com/en/docs/app.md), a [REST API](https://theirstack.com/en/docs/api-reference.md), [webhooks](https://theirstack.com/en/docs/webhooks.md), an [MCP server](https://theirstack.com/en/docs/mcp.md) and bulk [datasets](https://theirstack.com/en/docs/datasets.md).

Sales and marketing teams use it to [find companies whose job posts show they need what they sell](https://theirstack.com/en/use-cases/outbound.md) and to [keep their CRM accounts up to date](https://theirstack.com/en/use-cases/enrichment.md). [Sales intelligence and recruiting platforms embed it](https://theirstack.com/en/use-cases/embedded-data.md) in their own products, and [job boards](https://theirstack.com/en/use-cases/job-boards.md) use it to fill their listings. Analysts use it to [study hiring and technology adoption across a market](https://theirstack.com/en/use-cases/market-research.md).

Important notes:

- Every signal comes from job postings. Technographics are [inferred from what companies write in their job posts](https://theirstack.com/en/docs/data/technographic/how-we-source-tech-stack-data.md), not from scanning their websites, so they include internal tools (ERPs, databases, data warehouses, CRMs) that website scanners cannot see. Each detection has a confidence score and links back to the job posts it came from.
- Buying intent is also [read from job posts](https://theirstack.com/en/docs/data/buying-intent/how-we-source-buying-intent-data.md), not from web browsing or content consumption: 9.4k topics such as "ERP implementation" or "SOC 2 compliance".
- TheirStack is not a job board and has no email or phone database. Jobs include the [hiring manager](https://theirstack.com/en/docs/app/contact-data/hiring-manager.md) when the posting names one; emails and phones come through [integrations with Apollo and ContactOut](https://theirstack.com/en/docs/app/contact-data/find-people.md).
- Jobs are [deduplicated and normalized](https://theirstack.com/en/docs/data/job/data-workflow.md) across sources and tracked until they close ([`job.closed`](https://theirstack.com/en/docs/webhooks/event-type/webhook_job_closed.md)). [We find 73% of them the same day they are posted](https://theirstack.com/en/docs/data/job/freshness.md). History goes back to 2021 in the [datasets](https://theirstack.com/en/docs/datasets.md).
- Pricing is [public and self-serve](https://theirstack.com/en/pricing), in [credits](https://theirstack.com/en/docs/pricing/credits.md). API and webhooks: 1 credit per job, 3 per company. Credits are only spent when data is returned, and paid credits last 12 months. The [free plan](https://theirstack.com/en/docs/pricing/plans.md) gives 200 API credits and 50 company credits every month, without a credit card.
