Open Source
This tool is fully open-source. You can inspect the code, contribute to its development, and ensure full data sovereignty by hosting it yourself.

Project Description
Signal watches the web for buying signals (hiring changes, funding news, product launches, review shifts), enriches the companies and contacts behind them, drafts personalized outreach, and runs multi-step email sequences — all from a single chat-first workspace. Self-host on your own Supabase + Anthropic keys and own the pipeline end to end.
