Anti-Fragile take
TAM sourcing is not buying a list from ZoomInfo. It is resolving every company that matches your ICP, deduplicating, enriching, and scoring them so reps have a complete universe to work.
Most teams work 5% of their TAM because the other 95% was never sourced, resolved, or scored.
Why it matters
You cannot run signal monitors on accounts you do not know exist. TAM is the foundation under scoring and outbound.
How we build it
Multi-provider company discovery, warehouse dedupe, ICP scoring, and CRM sync with territory assignment.
