Why Scavio Wins

  • Multi-platform search data powers prospect research that goes beyond contact databases: find what prospects are discussing on Reddit, their YouTube content, and their Google visibility.
  • At $0.005/credit, researching 100 prospects across Google, Reddit, and YouTube costs $1.50 versus needing separate subscriptions for each data source.
  • Apollo is the better choice for teams that need contact data (emails and phone numbers). Scavio provides market intelligence, not contact databases.
  • MCP integration enables AI outbound agents that research prospects in real-time during sequence creation, personalizing emails with current web data.
  • Scavio does not index LinkedIn or provide firmographic data. For company enrichment, Clearbit remains the standard.
