Prophia
"The AI that reads the most boring documents in real estate - and finds the money hiding in them."
It is a Tuesday morning at 353 Sacramento Street, and somewhere in a Prophia data pipeline, a 187-page lease for a Class A office tower is being read faster than any human ever could - by a machine that actually understands what a "co-tenancy clause" means.
The lease, of course, does not care. It has been waiting in a property owner's shared drive for four years, gathering dust next to scanned PDFs of estoppels, amendments, and a side letter that someone signed in 2019 and promptly forgot. Prophia is the reason they will remember.
This is what commercial real estate looks like in 2026: a multi-trillion-dollar asset class still largely run on PDFs, spreadsheets, and the patient memory of one analyst named Brenda. Prophia is the small San Francisco company - 41 people, $17.7M raised, a quiet but persistent client list - that decided to do something about it.
Prophia calls itself a "lease intelligence platform." Translated from PropTech into English: it takes the unreadable stack of commercial leases that every building owner has been pretending to manage, extracts the data with AI, runs human quality control on top, and turns the result into a clean, searchable database of rent rolls, critical dates, stacking plans, and lease obligations.
The pitch is not that Prophia is glamorous. The pitch is that it is necessary. Asset managers were never supposed to be PDF archaeologists - and yet, for decades, they have been.
The base lease abstraction and CRE data management platform. Drop in a lease. Get out structured data, key dates, and clauses you actually need on Monday morning.
Roll Essentials up across an entire portfolio: rent rolls, stacking plans, critical date alerts, encumbrance tracking, audit-ready reporting.
A generative-AI feature that produces structured lease summaries on demand. Useful when the LOI is due tomorrow and the file room is in another time zone.
Models extract. People verify. The trick is the loop: machine speed plus human accountability for the data CRE actually trusts.
Prophia was incorporated in March 2018 by Cameron Steele and Chris Hsu. Both Stanford alums. Both veterans of the same hotel-tech startup, buuteeq, which Booking Holdings bought in 2014. Both, by their own admission, knew approximately nothing about commercial real estate when they began.
Steele had spent twenty-five years in software. After Booking and a stint at OpenTable, he went looking for an industry that had the size of consumer tech but the data hygiene of a 1990s law firm. Commercial real estate raised its hand. Hsu - the CTO, MS in Computer Science from Stanford, alum of Oracle and Booking.com - signed on to build the engine.
The company was originally called Leaseable. The rebrand to Prophia came when the founders realized the product was less about leases as documents and more about prophecy - what the lease portfolio is telling you about next quarter, next year, next refinance.
Co-Founder & CEO
Stanford undergrad, Dartmouth MBA. Founding executive at buuteeq (acquired by Booking Holdings, 2014). Previously at OpenTable.
Co-Founder & CTO
MS, Computer Science, Stanford. Enterprise cloud engineering across Oracle, Booking.com, and buuteeq before co-founding Prophia.
Cumulative; Series A round was $10.2M led by Cercano Management with SignalFire. Early-stage figures approximate.
Commercial real estate is the largest asset class on earth that still runs on documents written for humans and stored as images. A single mid-size office portfolio can have thousands of lease pages, each with clauses that move millions of dollars: percentage rent, exclusivity, co-tenancy, option to extend, restoration obligations at lease end.
Get any of those wrong in an acquisition diligence cycle and the spread evaporates. Get them wrong in an asset-management cycle and the NOI quietly leaks. Prophia's argument is that humans alone are too slow, and AI alone is too sloppy - so it sells the combination, not the magic.
The product fits inside the back office of asset managers, REITs, and private equity sponsors. The lease data flows out into partners like Cherre and into the dashboards owners already use. There is no pitch about "disrupting" anything. The pitch is: your analyst can stop typing.
Prophia spent its first three years as Leaseable. The new name nods at "prophecy" - what a portfolio of leases tells you about the future.
Both co-founders met at the hotel-tech startup buuteeq, which Booking Holdings acquired in 2014. The current Prophia stack carries the genetic memory.
Prophia publicly reported 100% customer retention through its Series A year - rare in any B2B category, rarer still in proptech.
Back at 353 Sacramento Street, the Tuesday-morning lease has finished its journey through the pipeline.
The 187-page PDF is now a structured record. Its critical dates have been flagged. Its co-tenancy clause is sitting in a dashboard a continent away, where an asset manager will glance at it before a 9 a.m. call. The side letter from 2019, the one that everyone forgot, is no longer forgotten.
Nothing about this scene is dramatic. There is no founder pacing the office. There is no demo gone right at the last minute. There is only the quiet, accumulating fact that commercial real estate has, for the first time, something that resembles a memory.
And Prophia, 41 people on a Tuesday in 2026, is the company writing it down.
