Personalized outreach converts at two to five times the rate of generic messages. The bottleneck is research: finding each prospect's recent news, social activity, company developments, and interests. The best personalization engines automate this research and feed it into outreach templates, turning hours of manual research into seconds of API calls.
Scavio powers outreach personalization by searching Google, Reddit, YouTube, and marketplaces for prospect signals at $0.005/credit, giving personalization engines the raw research data they need.

Why Scavio Wins
- Multi-platform research finds personalization signals that contact databases miss. A prospect's Reddit comments, YouTube channel, or marketplace presence tell you what generic CRM data cannot.
- $0.005/credit makes deep prospect research affordable at scale. Research 1,000 prospects across five platforms for $5-15 vs $134/mo for Clay's enrichment.
- MCP integration lets AI agents research prospects autonomously. Build a personalization agent that searches, compiles signals, and drafts personalized openers.
- Reddit signals are uniquely valuable for personalization. Referencing a prospect's actual Reddit discussion about their industry challenge shows genuine research, not template stuffing.
