Multi-source lead discovery vs. a contact database
A contact database sells you a static list everyone else also bought. Multi-source discovery routes your ICP across many live sources and finds the B2B companies you actually sell to — including the long tail one database misses. Here's the difference, and why it changes who you can reach.

Notes from rebuilding Overwise's outreach pipeline as an agentic system: a Sonnet executor that decides per-lead what to send, an Opus advisor for edge cases, and a MessageVerifier that discards drafts whose claims can't be cited. What we threw away, what we replaced it with, and why.
