What's next
License verification is just the beginning
We're building toward a single API that answers “is this contractor legit?” across every signal that matters. Here's the roadmap.
License Verification
Live nowReal-time license status, bond info, workers' comp, expiration dates, and state classifications across all 50 states.
Business Entity Checks
Q3 2026Secretary of State data. Registration status, incorporation type, registered agent, and filing history.
Litigation History
Q4 2026Court records, liens, judgments, and disciplinary actions from federal and state courts.
Permits & Zoning
2027Building permit history, zoning classifications, and code violations across US jurisdictions.
Each new signal gets its own endpoint and plugs into a unified contractor risk profile. Join the waitlist to get early access as each layer launches.
Why now
The regulatory window is opening
California SB 291
Tightening contractor verification with penalties up to $30K per violation. Effective 2026.
New Jersey P.L. 2023
New bond and insurance mandates for home improvement contractors. Education requirements effective Feb 2026.
Florida HB 735
Centralized all contractor licensing under state control as of July 2025. One source of truth.
States are tightening enforcement, but the tools to check contractor licenses are still stuck in the 90s. Manual portal lookups, no APIs, no structured data. We're fixing that.
