The agent queries 150+ data providers in waterfall sequence to identify companies matching your ICP criteria: vertical, company size, revenue band, geography, tech stack, funding stage, and headcount growth rate. Each provider has unique coverage — Apollo finds companies others miss, Clearbit covers newer companies better than legacy databases, LinkedIn company data captures recent changes faster than firmographic DBs. The waterfall approach means a company isn't missed just because one data provider doesn't have it.

A raw company list isn't a TAM — it's a spreadsheet. The agent enriches every identified account with verified data from multiple sources: revenue band, employee count, industry classification, known tech stack, funding history, and growth rate. Data conflicts between sources are resolved by confidence scoring — the most recently verified, most-source-confirmed value wins. The result is a single unified account record per company with the enrichment quality and recency information visible, so you know which fields to trust.

A raw list of 5,000 companies isn't actionable. The agent segments the TAM into tiers based on ICP fit criteria you define: Tier 1 (best-fit, highest-priority outreach), Tier 2 (good fit, secondary motion), Tier 3 (longer-term, lower-priority). Segmentation criteria can include any combination of firmographic, technographic, and signal-based attributes — including accounts that are already showing intent signals or hiring surges. The tier model is recalculated as new enrichment data arrives, so accounts can graduate or drop based on current signals.

A TAM that lives in a spreadsheet is a static artifact that becomes outdated immediately. The agent syncs the TAM to your CRM as account records, maintaining ownership, tier, and enrichment data. New companies that match ICP criteria are added automatically as they're discovered. Companies that no longer match (acquisition, pivot, shutdown) are flagged for review. The TAM is a live, maintained dataset — not a quarterly exercise that's outdated the day it's exported.
