About SubForge

The short version

If you sell products or services to commercial contractors, you need accurate contact data. You need to know which contractors are actively licensed, which trades they specialize in, what project types they focus on, and how to reach the decision-makers who actually buy what you sell.

Generic B2B databases like ZoomInfo and Apollo were not built for this. They cannot verify license status. They cannot distinguish a commercial mechanical contractor from a residential HVAC firm. They cannot segment by trade or project type beyond NAICS codes.

SubForge was built specifically to solve this problem. We source data from state contractor licensing boards, cross-reference against project records and business filings, and verify every email and phone number before delivery.

How we got here

SubForge is part of the Provyx family of data products. Provyx builds verified contact data across healthcare, veterinary, financial advisory, legal, and other industries with hard-to-source decision-makers. We built SubForge as a dedicated brand for commercial construction because contractor data has unique sourcing requirements that don't fit neatly into a general B2B data product.

State contractor boards publish data differently than medical boards or bar associations. The trade taxonomy is different. The buyer ecosystem (construction software, equipment OEMs, surety underwriters, material suppliers) has different needs. SubForge exists because this market deserves a purpose-built solution.

Why we don't sell subcontractor data

Some buyers ask for "subcontractor lists." We don't sell those, because the data doesn't cleanly exist. Whether a firm is a sub or a GC depends on the project, not the firm. A mechanical contractor might be a sub on one project and the prime on another. State boards license trades, not project roles.

What we sell is commercial contractor data segmented by trade and project type. If you want mechanical contractors who typically work as MEP subs on commercial healthcare projects, we can build that list. The classification is real. The "subcontractor" label is just a project-level role.

Our team

SubForge is led by Rome Thorndike, who built data infrastructure at Datajoy (acquired by Databricks) and has held data roles at Microsoft, Salesforce, and Snapdocs. He holds an MBA from UC Berkeley Haas.

The team has deep experience in data operations, B2B enrichment, and regulated industry intelligence. We've built data pipelines that serve companies from Series A startups to Fortune 500 enterprises.

What we believe

Data quality matters more than data quantity. A list of 500 license-verified, trade-classified commercial contractors with accurate emails beats a list of 5,000 unverified contacts with 20% bounce rates. Every time.

We don't sell platforms. We don't lock you into annual contracts. We build the data, verify it, and send it to you. That's the business model. If the data is good, you'll come back. If it isn't, you shouldn't have to.
