<1% of owners appeal each year, yet >50% are over-assessed. $4.2B in recoverable overpayments go unfiled annually in Texas alone.
10,000 licensed firms run leads in spreadsheets and file through archaic county portals. They spend $5K–$50K/year on direct mail just to find clients.
$2B+/year in property tax loans are originated with no way to reduce the underlying bill — so borrowers stay over-taxed and at higher risk.
Each with different data, portals, and rules. No statewide standard — and no purpose-built software connecting any of the three sides.
Gumyum AI sits in the center of all three sides — and earns on every transaction.
2026 TX assessments up 10–20%; appeals are surging.
True Prodigy's first open APIs make integration possible — it wasn't 3 years ago.
LLM agents can now do hearing prep and case strategy at consultant quality.

Everyone else picks one side. Gumyum is the connective infrastructure for all three — the platform, not the app.
Consumer protest service — app layer only. No data infrastructure, no PTC platform.
Institutional SFR only. Won't serve homeowners or small landlords — complementary, not competing.
Property tax loans only — can't reduce the underlying bill. A distribution partner, not a competitor.
The real competitor: inertia. Manual lead tracking with no workflow lock-in and no AI.
One integrated workflow for tax consultants — live today with Vanguard Tax Appeals:
A closed-loop AI system that gets smarter with every case filed and every outcome recorded.
