SubForge vs ZoomInfo for Construction Data

The short version

If you're selling specifically to commercial contractors, SubForge delivers more accurate, more targeted contact data than ZoomInfo. We source from state contractor boards, segment by 16 trade categories and 8 project types, and verify every contractor's license status. ZoomInfo cannot do any of this.

Accuracy

SubForge starts with state contractor licensing boards, the authoritative source for every commercially licensed firm. We cross-reference against project filings, business registrations, and firm directories. The result is data verified against the same records that state regulators use to enforce licensing law.

ZoomInfo relies on web scraping, email signatures, and crowdsourced data. For tech companies with large online footprints, this works. For commercial contractors who do their work in the field and rarely update LinkedIn, the accuracy drops significantly.

Trade segmentation

SubForge segments by 16 commercial trade categories with 25+ subcategories. General contractors break into design-build, CM, healthcare, K-12, higher ed, multifamily, hospitality, and industrial GCs. Mechanical breaks into HVAC, sheet metal, refrigeration, controls, and plumbing. ZoomInfo classifies all construction businesses under a handful of NAICS codes with no distinction between a $200M mechanical contractor and a residential remodeler.

Pricing

SubForge charges $0.50 to $1.50 per record on a per-project basis. No annual contract. No seat licenses. A list of 1,000 license-verified commercial contractors costs $500 to $1,500, delivered in 3-5 days. ZoomInfo starts at $15K per year for an enterprise contract.

When to use SubForge

If you sell specifically to commercial contractors. If you need license-verified contacts segmented by trade and project type. If you want accurate data without an annual contract. If you'd rather spend your budget on data quality than platform access.

When ZoomInfo is the better fit

If your TAM extends well beyond commercial construction. If you need intent data, technographics, and email sequencing in a single platform. If you have the budget for an enterprise contract and value workflow integration over data depth.
