Sonar.
A signal-driven lead engine. Finds founders 4 to 5 weeks before competitors notice them. Hiring posts, funding rounds, public pain. Sourced, ranked, enriched, ready for the sequencer.
Signals tell you when an account is in-market.
Most outbound starts with a list. Apollo, ZoomInfo, the same data every founder is buying. Sonar starts with signals: real, observable evidence that the account is in-market right now.
- ICP matching. Standard demographic match against a target shape. The fallback layer.
- Signal research. Web scraping for hiring, funding, launches, public complaints. The lead layer.
- LinkedIn engagement. People commenting on competitor content, attending category events.
- Graph queries. Planned. Find accounts based on relationships and second-degree signals.
Built for production.
Next.js dashboard. Python enrichment pipeline (10 stages: source, dedupe, classify, verify email, verify mobile, score, rank, segment, hand-off). Supabase for state. Open source on GitHub.
statusI run my own outbound through it.
Every client build runs through it too. v0.4 is in production. v1.0 ships with the graph layer wired in.
