We have direct integrations with top-tier third-party contact data providers such as Apollo.io, ContactOut, and LinkedIn [see this guide for more information](/en/docs/app/contact-data/find-people). Additionally, we offer [hiring manager information for applicable jobs](/en/docs/app/contact-data/hiring-manager), including the recruiter's name, position, and LinkedIn profile.

However, we do not supply contact data directly for several reasons:

-   Rather than attempting to cover multiple areas, we focus on excelling in one—helping you identify companies with strong purchasing intent. As a small company, we must choose our priorities wisely.
-   Collecting and distributing personal contact data may not comply with GDPR regulations, despite being a common practice among many contact data providers.

-   [Find people](/en/docs/app/contact-data/find-people) — Find email and phone numbers for decision-makers at companies using TheirStack integrations with Apollo, ContactOut, Instantly, LinkedIn Recruiter, and Sales Navigator
-   [Hiring Manager](/en/docs/app/contact-data/hiring-manager) — Discover hiring manager data with names, roles, and LinkedIn profile URLs for job postings. Access and filter via TheirStack's UI and API platform.
