Your 5-person startup needs prospect emails AND wants to run outreach sequences. Which tool lets you do both without paying for separate products?
Right! Apollo.io is the only one with a built-in contact database (275M+). Outreach.io has superior sequencing, but you'd need a separate data provider (like ZoomInfo or Lusha) to find prospect emails.
