Key insight: Subcontractors will pay $15-30/month to never miss a lien deadline because one missed window costs them $5K-50K in unpaid invoices — but they're invisible to legal tech VCs who only see B2B law firm SaaS.

The Problem

Subcontractors often miss critical deadlines to file mechanic's liens (30-120 days depending on state) when GCs don't pay, losing their legal right to recover. Manually tracking project timelines, state-specific filing deadlines, and required documentation across multiple jobs is error-prone and expensive.

Target Audience

Solo and small-team subcontractors (electricians, plumbers, roofers, HVAC) in residential/commercial construction who work under GCs and frequently face payment delays.

Why Now?

Construction payment disputes hit record levels post-2023; subcontractors are desperate for cheap solutions to protect themselves without hiring lawyers ($500+ per filing).

What's Missing

Existing legal tech targets law firms, not trade workers. Lien filing is repetitive but state-specific, making it perfect for automation but not worth a law firm's dev resources.
