The record is scattered
County values, notices, tax bills, protest status, and outcome documents sit in different places. Owners need one clear view before money is spent.

Source-backed property-tax record for commercial owners, managers, advisors, and filing partners.
Independent control over commercial property tax.
Regilon is the record that follows a commercial property tax case from the official source to a verified outcome — so owners can see what is known, what is estimated, what needs review, and what money has actually been confirmed.
One independent record that audits all four.
Commercial property tax asks an owner to trust four separate things: the county’s assessment, the representative who files, the outcome that comes back, and the fee they are charged. Regilon holds the record that checks each one against its official source.
Regilon is not a property-tax appeal agency. We monitor exposure every year and generate evidence only when the economics justify action.
Overpayment is a workflow problem first.
Most commercial owners have no clean path from county data to missing documents to a reviewed packet to verified savings. The money leaks in the gaps between those steps.
Deadlines move by jurisdiction
Appeal windows depend on county rules, notice dates, and filing status. Miss the window and a good case becomes next year’s problem.
Evidence is hard to assemble
A case may need bills, notices, rent rolls, sale support, filing proof, hearing notices, ARB orders, or revised bills. Most owners cannot see what each document unlocks.
Estimates read like outcomes
A screening estimate is a useful planning signal, not a billable result. Verified savings require source-backed outcome proof — the two are never blurred.
From official source to verified outcome.
Four stages carry a case, and each hands the next an explicit state. Nothing advances by inference — a missing or failed source stays unknown until a real document resolves it.
Start from the official source
Every case begins at the account-specific CAD, ARB, and tax-office record — not a guess. The public source is captured with its as-of date and proof status.
Resolve one canonical fact
One record is scoped per property, jurisdiction, and tax year. Home, documents, case, packet, and ledger read from that single record, so every surface agrees.
A reviewer clears the case
Comparable QA, packet limits, and customer-facing labels are checked by a reviewer before checkout opens. If a gate holds, the property shows the reason — not a payment button.
Verify the outcome against the bill
Savings graduate only when an ARB order, corrected notice, or revised tax bill confirms them. A missing or failed source stays unknown — it never becomes zero or clear by inference.
Higher-authority evidence is never silently replaced by something weaker.

Unverified extraction
A candidate field or inference — never authoritative on its own
An estimate is never a verified saving.
Savings move through five explicit proof stages. A property counts toward executive totals at only its highest qualifying stage, and nothing double-counts.
Payment, packet access, reviewer clearance, filing readiness, official submission, outcome confirmation, bill verification, and cash realization are tracked as independent states. A success fee applies only after an outcome the documents confirm.

Live in Texas today. Built county by county.
Regilon is an early-stage company. We go deep on one market before we widen, because a source-backed record is only as honest as the jurisdiction rules behind it.
Savings and filing recommendations are calibrated on Harris commercial ARB outcome rows with property-level holdout tests, then validated on properties the model did not train on.
