Building an AI sourcer that actually finds the right talent

Spent the last few weekends building an AI sourcing agent. Quick version: feed it a role, it ranks candidates, drafts the outreach. The model layer was the easy part. The data layer is where every project like this quietly dies. Every "B2B data" provider gives you the same five filters - job title, location, company, seniority, industry - and a giant pool of half-stale profiles. So your "AI sourcer" ends up recommending the same 200 people as everyone else's AI sourcer, with last-quarter's job titles. That's not a sourcing agent. That's a list rental.
