  • Generous free plan for testing
  • All-in-one: data, sequences, dialer, and analytics
  • Affordable pricing ($49/user/mo, no annual contract required)
  • 4.7/5 on G2 with 9,000+ reviews

What is Outreach.io?

Outreach.io is an enterprise sales engagement and revenue intelligence platform. It does not include a contact database, instead, it focuses on being the best engagement and analytics layer for sales teams that already have their prospect data.

  • Conversation intelligence (Kaia) with call recording and AI summaries
  • Advanced deal management and pipeline tracking
  • AI-powered revenue forecasting
  • Deep, bi-directional Salesforce integration

Key weaknesses:

  • Expensive, reportedly $100+/user/mo with annual contracts
  • Onboarding fees of $5,000–$15,000+ reported
  • Steep learning curve (2–4 weeks for new reps)
  • No contact database included
  • Poor HubSpot integration
  • LinkedIn steps are manual reminders, not automation

Test yourself

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.

💡

Only Apollo.io includes a contact database. Outreach.io is a pure engagement platform, you need to bring your own prospect data from another source.

How to decide between them

  1. Do you have prospect data already? If no, Apollo wins by default. Outreach requires you to bring your own contacts from a separate tool.
  2. What's your team size? Under 20 reps: Apollo. Over 50 reps with dedicated sales ops: Outreach starts to make sense.
  3. What's your CRM? Salesforce: both work, but Outreach integrates deeper. HubSpot: choose Apollo.
  4. Do you need conversation intelligence? Call recording, AI summaries, deal health scores? Only Outreach has these built in.
  5. What's your budget? Under $50/user/month: Apollo. $100+/user/month with annual commitment: Outreach is an option.

Who should choose Apollo.io?

  • SMB and mid-market teams that want data + outreach in one tool
  • Startups that can't afford Outreach's enterprise pricing
  • Teams that want to test before committing (free plan available)
  • Companies using HubSpot as their CRM
  • Solo founders and small teams that need quick prospecting

Who should choose Outreach.io?

  • Enterprise sales teams with 50+ reps
  • Companies using Salesforce that need deep integration
  • Teams that need conversation intelligence and call recording
  • Sales leaders who need advanced analytics and revenue forecasting
  • Organizations with dedicated sales ops to manage the platform

🎉

Correct! Outreach's Kaia provides conversation intelligence with call recording, AI summaries, and deal health scores. Apollo.io does not have conversation intelligence built in.

💡

Only Outreach.io includes conversation intelligence (Kaia) with call recording, AI summaries, and deal health scores. Apollo.io has a basic dialer but no conversation intelligence features.
