Key insight: Property tax appeals are the most profitable (and laziest) quick-win for property owners because of information asymmetry and jurisdictional complexity—automating this creates 10-20% instant ROI per property, but no one has productized the cross-county aggregation layer.

The Problem

Property owners typically discover tax assessment increases only when the bill arrives, missing critical dispute windows (often 30-60 days). Each county has different appeal procedures, deadlines, and documentation requirements, making it impossible to track manually across multiple properties. Most property managers handle this reactively, losing thousands in preventable overpayments.

Target Audience

Individual landlords with 5-50 rental properties, regional property management companies, and tax consultants who manage client portfolios

Why Now?

AI-powered web scraping and OCR have made county record parsing feasible; rising property values post-pandemic mean assessment increases are aggressive and frequent; property managers are desperate for automation

What's Missing

County assessor systems are siloed and fragmented by jurisdiction—no unified API. Existing property management software ignores tax tracking entirely, and accountants don't proactively monitor unless paid separately.
