You pay per module to see your own data
Accounting, payments, maintenance, reporting — each one a separate line on the invoice. The fee stack grows faster than your portfolio does.
AI-native property management
The property platform that audits itself.
One system for residential and commercial portfolios — with AI that surfaces real dollar discrepancies in your books before they reach an owner's statement. Built for operators running 1,000 to 15,000+ units.

The status quo
Legacy property software charges you more to see less.
Yardi and AppFolio were built for a different decade. The cost compounds, the data fragments, and the errors stay invisible until they cost you an owner relationship.
Errors hide in reconciliation nobody has time for
Misapplied fees, duplicate payments, under-billed CAM charges. They clear quietly and surface months later — if they surface at all.
Residential and commercial live in separate tools
Mixed portfolios get stitched together in spreadsheets. One source of truth becomes two, then ten exported tabs.
The audit
We'll find the money your system lost. Before you pay us a cent.
Most vendors open with a slideshow. We open with your own financials. Give us a historical export and Sentinel runs a read-only audit alongside your existing system — then hands you a dollar-figure list of what it found.

01
Connect, read-only
We ingest a historical export from your current system. Nothing is written back. Your live operation never changes.
02
AI audits every transaction
Sentinel re-derives your ledger from first principles and flags where the numbers don't reconcile — line by line, with the dollar amount attached.
03
You get a findings report
A categorized list of real discrepancies and what they're worth. No commitment. The audit is the demo.
The platform
One system that replaces the entire stack.
Not seven modules with seven invoices. Accounting, payments, leasing, maintenance, and reporting — residential and commercial — on a single AI-native platform.
AI error detection
The only PM platform that audits its own ledger in real time.
Every posting is re-checked against lease terms, vendor contracts, and accounting rules. When something doesn't reconcile, you see it the same day — not at year-end.

ResidentialCommercial
One platform for mixed portfolios
Multifamily, single-family, retail, and office in the same ledger. CAM, percentage rent, and resident charges — no spreadsheet bridge.
Software your team will actually use
Keyboard-first, fast, and legible. Onboarding in days, not the six-month implementation Yardi quotes you.
Payments
Money movement you can reconcile to the cent.
Collect rent, pay vendors, and disburse to owners inside the same system that audits them. Every dollar carries its own trail — so the books are right before anyone closes them.
- ACH, card, and lockbox rent collection
- AP with duplicate-payment detection built in
- Owner statements generated from reconciled data
- Trust-accounting rules enforced automatically

Trust & methodology
A zero-risk way to evaluate financial software.
Switching systems is the scariest decision an ops leader makes. So we designed the evaluation to carry none of the risk.
Read-only by default
The evaluation never writes to your system of record. Sentinel runs alongside it — your live operation is untouched until you choose to migrate.
Parallel-run methodology
Run both systems side by side for a full close cycle. Compare the numbers yourself before anyone signs anything.
Encrypted, access-scoped data
Financial data is encrypted in transit and at rest, with role-based access and a full audit log of every view and export.
SOC 2 posture
Controls aligned to SOC 2 Type II, with a documented data-handling policy you can hand straight to your CFO. (Placeholder claim — confirm before launch.)
See what your books have been hiding.
Send us a historical export. We'll run a free, read-only audit and show you the dollar figure your current system never surfaced.
