Where they pull apart

Apollo

Stands out: A large people database plus email sequences in one login, with MCP and a Chrome extension.

Watch out: Data quality varies by segment, and it does not match enterprise tools for intent data and org charts.

Not the right fit for

  • Buyers who need enterprise-class intent and org charts
  • Teams that want an ATS

TheirStack

Stands out: The depth of its job-posting archive: the vendor lists 225M postings back to 2021 across 195 countries and 352k sources, adds about 305k a day, and keeps closed jobs with the date each role went offline. Saved searches send daily or weekly email alerts or push to a webhook, so a desk hears the day a target company opens a role it places.

Watch out: It gives you the company and the posting, not the person: there are no emails or phone numbers for hiring managers, so you still need an enrichment tool to reach anyone. App credits and API credits are separate pools, and each app export is capped at 200 jobs per company.

Not the right fit for

  • Recruiters who need candidate profiles or contact details
  • Teams that want contacts and hiring signals in a single tool

Pros and cons

Apollo

  • Free tier, then a roughly $49/mo paid start
  • Database plus sequences in one login

  • Credit model needs watching

TheirStack

  • Free plan every month with both company and API credits
  • Closed jobs are kept and dated, not just live ones
  • Email alerts and webhooks for new postings
  • API, webhooks and MCP server on every API plan
  • No contact data for hiring managers
  • Separate credit pools for the app and the API
  • App exports capped at 200 jobs per company
