OfficialIteratively size your ICP with workable filters.
System Documentation
What problem does it solve?
This Skill turns an ICP description into a quantified TAM by iteratively resolving and validating the firmographic/technographic filter set against ZoomInfo’s verified company database, so you can both get a count and produce a reusable filter artifact.
Core Features & Use Cases
- Iterative TAM sizing with filter refinement: Produces a headline company count and actionable refinement options across multiple passes until the ICP feels right.
- Taxonomy resolution with safeguards: Uses taxonomy lookups for industry terms and blocks silent fallback when a taxonomy match is missing, prompting you to confirm or adjust.
- Data-sparsity and noise handling: Runs a data-sparsity probe for revenue/funding constraints and applies noise-adjusted TAM when keyword/taxonomy results appear noisy.
Use cases include territory and capacity design, investor-ready market sizing, and ICP sharpening that other skills can immediately reuse as a working filter set.
Quick Start
Ask for TAM for a described ICP, for example: "Size the TAM for my ICP of B2B cybersecurity software companies in the US with 200-1000 employees, and refine my filters until the universe matches my intent."
