Your lease data isn't wrong in one place. It's wrong in five.
The main lease says one commencement date. An amendment moves it. The commencement letter moves it again. Yardi was never updated, and the leasing team is still working from a spreadsheet nobody owns. Five documents, five answers, and real money riding on whichever one your team happens to trust.
This isn't a mom-and-pop problem. Prophia has audited the rent rolls behind 5,500 buildings; specifically, portfolios run by BIG names like Nuveen, Macerich, and Blackstone-caliber institutions. One in two rent rolls contained a financial error above $50,000. One Manhattan owner had a base year sitting untouched in Yardi since 2012, compounding into a ~$200,000 liability. Another had completely forgotten a license agreement signed a decade ago, until Prophia caught a reference to it buried in a 2024 document and helped the owner recover ~$800,000 in back rent, plus $120,000 a year going forward.
We sat down with Cameron Steele and Jeremy Bergeron to see exactly how Prophia does it: reconciling a lease file's full document history, rebuilding the economics, and linking every answer back to the controlling source language.

TOOL OF THE WEEK

What Prophia Is:
Prophia turns the documents that govern commercial real estate into verified, structured data that owners and investors can trust across an entire portfolio. The platform powers data behind 650M+ square feet across office, medical office, life science, retail, and industrial, and it has processed roughly 300,000 leases with nearly 3 million human-verified data points.
It is not a lease abstraction tool. Prophia connects the original lease, every amendment, commencement letters, and related agreements into one evolving record, the full story of the lease rather than a snapshot of it. Every extracted term links back to the controlling source language, so teams verify the answer in seconds instead of taking the software's word for it. No human ever types data into the system; extraction is AI-driven, with Prophia's own team handling exceptions.
That distinction matters because lease data rarely stays inside one document. Which brings us to the demo…
| WHAT WE SAW IN THE DEMO |
Jeremy opened a lease file where two units in the same lease carried two different commencement dates, and one of those dates had been cited or modified across five separate documents. When the 2020 amendment was signed, commencement was expected to be January 2021. A commencement letter later moved it to April. Prophia tracked that evolution, identified the controlling date, and automatically recalculated everything downstream of it: the rent schedule, the rent escalations, even the notice windows on renewal options. Nobody reconciled five files by hand.
From there, the demo widened out:
A stacking plan that maintains itself. Every suite shows a count of the encumbrances sitting on it. Click a vacant unit and see that a tenant holds a right of first offer on the entire floor, with a five-day acceptance period, all linked to the clause that created it. Leasing decisions that used to take a week of triangulating abstracts, Yardi, and side spreadsheets happen in minutes.
A critical date calendar that comes to you. Prophia tracks every date buried in your leases: renewal notice windows, termination rights, rent step-ups, expirations. Instead of relying on sticky notes or someone's calendar reminder, each person sets their own email alerts based on their role. An asset manager might want nine months of runway before a renewal notice deadline. A property accountant might want a heads-up before a rent increase kicks in, so the tenant gets invoiced the new amount on time. And when a tenant misses their notice window, Prophia automatically expires the option, so nobody accidentally honors a right that no longer exists.
Portfolio-level answers on demand. Ask a question like which leases expire in 2027, and how much annual rent is tied to them?" and get the answer instantly. Prophia takes every lease in your portfolio and builds one live view across all of it. You can filter that view by fund, by asset manager, or by property manager, and click any number to see exactly which tenants and expiration dates sit behind it. The data refreshes every hour and every figure links back to the contract it came from. No more waiting until quarter-end for property managers to pass spreadsheets around.
An AI assistant with receipts. Saved research prompts like "which tenants have ROFOs or ROFRs" return full reports where every footnote links back to the source document. And because Prophia is MCP-capable, teams that live in Claude, Copilot, or OpenAI can query the same verified data without ever opening the platform.
| THE NUMBERS THAT STOPPED US |
The rent roll stat from the top of this email (1 in 2 rent rolls contain financial errors) isn't even close to the entire picture. Prophia has processed close to 300,000 commercial leases and built a dataset of nearly 3 million human-validated annotations, and the audits keep surfacing the same patterns:
1 in 10 leases has a financial error sitting in the rent roll: missed rent steps, wrong abatement periods, incorrect dates.
More than 15% of tracked renewal notice periods are off by more than a year.
1 in 15 tenants has a pro-rata share error exceeding 10%, distorting every expense reimbursement (OpEx, taxes, and CAM) tied to it.
The average building is missing at least three main lease agreements or amendments from its own shared drives, which owners typically discover at the worst possible times (mid-refinance or mid-sale, in front of a lender or buyer).
Here's an example that shows what those percentages mean in actual dollars: A well-known logistics operator was set to end a lease with a major international retailer two months early because of a typo in Yardi. The tenant was paying over $600,000 a month. Prophia caught it during onboarding and locked in $1.2 million of rent the owner didn't know it was about to lose.
Cameron's explanation for why this keeps happening stuck with us: “tenants complain when they're overbilled. They stay quiet when they're underbilled.” The errors that survive are the ones that cost the owner money, which is why Prophia's audits so often turn into found revenue.
| THE COST OF DOING THIS MANUALLY |
Think about who is involved in a single leasing decision: an asset manager, a property manager, a leasing broker, sometimes a property accountant. Four people, and in most organizations, four slightly different versions of the same lease data (and no doubt four different opinions on what to do or how to handle a certain situation). However, Jeremy told us most of these individuals time isn't spent deciding. It's spent re-validating information so they can decide.
That's the work Prophia removes. The familiar CRE scavenger hunt (search the shared drive, check the abstract, compare to Yardi, then find the side spreadsheet someone maintains because nobody fully trusts the other systems) collapses into one click that lands on the controlling language.
The cost of running that scavenger hunt manually can get ugly, and it gets ugly fast. Jeremy told us about an operator in the Southeast that signed a new lease without clearing a right of first offer. The existing tenant flagged that it was never given its offer, and the owner had to rip up the newly signed deal. Then came the second blow: that same tenant exercised a termination option it already held on its own space and walked out of the building entirely. The owner lost the new lease and the existing tenant in one stroke, and the knock-on effects ultimately pushed the asset into default. One missed encumbrance took down an entire building.
The upside cases are just as telling. Beacon Capital's asset manager on a major LA asset assumed his CBRE brokers were manually building the critical-date reports and stacking plans they sent him every month. They weren't. The brokers were pulling everything from Prophia; the asset manager had no idea. And Spear Street Capital, a customer since 2019, hands qualified buyers direct platform access when a property goes to market: every lease organized, verified, and linked to source, which speeds up diligence and, in their experience, improves close rates.
Prophia calls it a lease war room: transaction-ready at all times, whether the next event is a disposition, a refi, or a recap. “Stay ready so you don’t have to get ready.”
One more thing worth knowing: none of this data goes stale. Prophia refreshes hourly as new documents are processed, and nobody at the customer ever types data into the system.
| THE BEFORE AND AFTER |
Jeremy says owners, operators, and investors buy Prophia for three reasons:
They want their historical documents audited before the errors compound.
They want their time back. The ask he hears most is some version of "give me 90% of my lease-workflow hours back."
They want to grow without hiring an army of manual headcount to train and retain along the way.
But the sharpest before-and-after in our conversation was about software economics. Cameron, who has spent 35 years in software, described the legacy model bluntly: vendors sell you an expensive system, and then you spend more maintaining it than you ever paid in licensing, because the system depends on your people manually typing data in and keeping it current.
Prophia inverts that. The platform arrives pre-populated from your documents, nobody on your team enters data, and the pricing is fixed rather than usage-based, so the AI tokenization costs that have blown up budgets elsewhere are Prophia's problem, not yours.
Cameron's framing stuck with us: the industry is moving from software as a record of work to software that gets work done. "Don't sell me a product and create work for me. Give me the solution, help me get work done."
| OUR HONEST TAKE |
We demo AI and prop-tech tools for a living, and we don't say this often: Prophia is one of the most complete platforms we've seen in this space. On the podcast we called it “AI for CRE Collective approved,” and we meant it.
The core of that statement comes down to the fact that the trust layer is the product. A general AI model can summarize a lease, and for a first-pass read it's great. But Jeremy told us companies who tried generic tools found them accurate roughly 60% of the time. And 60% is worthless when you're underwriting to the answer, managing a risk covenant, or betting a capital decision on a date. Prophia is built for those deterministic decisions. It combines AI extraction with expert review, owns the exception-handling process end to end, and backs it with a moat no claude-wrapper can replicate: 300,000 leases processed and nearly 3 million human-verified annotations to test against.
Prophia is deliberately narrow, and you should know if you're outside its lane. It serves commercial property owners and investors only; occupiers, brokers, and lenders are not target customers today, and Cameron was refreshingly blunt that he's uninterested in chasing them. Asset classes center on office, medical office, life science, retail, and industrial. Multifamily is out. And the sweet spot skews institutional: this is an enterprise data implementation with real onboarding, not a self-serve tool you activate in five minutes. If you're a smaller regional owner, the value proposition is there but the fit conversation needs consideration.
For the customers Prophia does serve, the platform is operating at serious scale, and its scope is expanding. Loan documents launch next, bringing covenant tracking and compliance reporting onto the platform. Beyond that, the team is building AI agents it will own and maintain for customers, plus generative AI applications built on a proprietary dataset nobody else has.
BONUS
The most provocative moment of the conversation came when Cameron dismissed the product category most AI startups in this space are built around.
"Lease abstracts are dead," he told us. His argument: abstracts only exist because lease data used to be locked in documents nobody could search. The abstract was a workaround, a summary you built because the real answer was too buried to reach. Once every data point is extracted, verified, and linked back to its source language, the summary report has nothing left to do. "The reason you're doing this is because there's a question you want to answer. Just tell me that, give me context, and give me the ability to audit it."
Think about how many companies are marketing themselves right now as AI lease abstraction tools. Cameron's point is that they're automating an artifact of the old problem instead of solving the new one. You don't want a faster abstract. You want the answer, with a link to the clause that proves it.
Worth sitting with, whether or not you're a Prophia customer (or a founder in the AI or prop-tech space).
