Our verdict
Job postings and technology data as buying signals, at a good price.
What it is
A database of job postings from many job boards, with the technologies each company uses inferred from those posts. You can find accounts hiring for a role or adopting a tool.
Best for
Outbound plays triggered by hiring, such as a company hiring its first RevOps lead or adopting a competitor.
Not the right fit
Teams wanting contact data.
Key capabilities

API
Signals by query.
Strengths
- Hiring signals by keyword, title and technology
- Large job-posting coverage with history
- API and alerts for new matches
Watch-outs

- Needs careful keywords to avoid noise
Pricing
Credit-based plans with a free tier.
Pricing summarised in October 2026 and not re-checked since. Vendors change plans often, so confirm current pricing with TheirStack before you budget.
Security and governance
Intent and visitor data mixes company and sometimes personal data. Check consent and cookie requirements in each market you sell to, how identification is done, and whether the vendor offers a data processing agreement and regional hosting.
