But He Does Want Your Data.
Rocket Companies chose a new CEO for recently acquired real estate brokerage Redfin Corporation, and he has no real estate experience.
The choice tells us a lot about where Rocket wants to take the online brokerage and, more broadly, how it sees the giant real estate portal.
The MetaData Rocket Man
Alessio Sanfilippo was Vice President of Insights for Meta’s Reality Labs, overseeing data science, data engineering and user research supporting Meta’s AI-enabled smart-glasses business.
On September 4th, Meta was hit with a proposed nationwide class action lawsuit involving NameTag, the facial-recognition system developed for its smart glasses, and Meta’s generative AI systems.
According to WIRED, the plaintiffs allege that Meta “illegally used their Facebook and Instagram photos to build NameTag” and to train its Emu and Muse Image generative AI models. “The proposed class action alleges that Meta violated Illinois and California privacy laws by extracting biometric information from people’s photos without notice or consent.” Meta says the lawsuit is without merit and misrepresents its work.
Sanfilippo wasn’t a peripheral executive at Reality Labs. He led global teams across data science, data engineering and user research. In a 2025 reorganization, Meta consolidated its Analytics and User Experience Research teams under Sanfilippo as “RL Insights,” reporting directly to Meta CTO Andrew Bosworth and charged with driving the organization’s “data and customer-focus efforts within the product group.”
Now he’s running Redfin.
A home-search platform that explicitly contemplates collecting behavioral information and making inferences about its users. And the front door to one of the most vertically integrated housing and financial-services ecosystems in the country.
Real estate? MetaData Rocket Man wouldn’t know Regulation Z from a Zebra because he has Zero experience in the real estate realm.
There Is A Real Estate Guy
Redfin isn’t without experienced real estate leadership. Jason Aleem continues to serve as Chief of Real Estate Services, leading Redfin’s nationwide network of agents and overseeing brokerage client service and sales strategy. A former broker and agent, he joined Redfin in 2010 and has spent much of his career building and running the company’s real estate operations.
He’s also deeply involved in integrating Redfin’s brokerage with Rocket’s larger homeownership platform. So Rocket already has an experienced real estate executive overseeing the real estate business.
What it went outside the company to find was something else.
Rocket screened more than 200 candidates before choosing Sanfilippo, whose expertise is data science, data engineering, user research and AI. And it put him in the CEO’s chair.
The distinction is revealing. Aleem provides the real estate expertise Redfin needs to operate as a brokerage, but Sanfilippo brings the data expertise Rocket has repeatedly identified as central to Redfin’s value and its future.
If Rocket Wanted A Data Company, Why Did It Buy A Real Estate Portal?
That question kind of answers itself, doesn’t it? How many common consumer transactions exceed a real estate purchase in monetary value? It’s a sector surrounded by services attached to the same transaction, each creating another opportunity to capture revenue and extend the customer relationship.
If you’re still wondering, here it is, out of the mouths of data-drooling corporate execs:
When Rocket announced its $1.75 billion acquisition of Redfin in March 2025, CEO Varun Krishna spoke briefly about real estate. He described Redfin as the nation’s top-ranked brokerage, cited its 2,200 lead agents and 61,000 transactions the previous year, but quickly shifted into the subject of connecting search, buying, selling, mortgage, title and servicing.
When Krishna referred to Redfin’s nearly 50 million monthly visitors, it was as consumers with “strong intent to transact” and the combination as a “highly efficient funnel.” Rocket projected more than $60 million in revenue synergies from pairing Rocket financing clients with Redfin agents and steering Redfin clients toward Rocket mortgage, title and servicing products.
And Krishna talked a lot about data.
“In today’s world, the companies with the most data will win,” he said.
Krishna described the combined companies as holding more than 14 petabytes of data, including Redfin buyer interactions, property information and pricing trends. He said the combination would create “unparalleled consumer insights” and strengthen Rocket’s AI models and ability to personalize the consumer experience.
And 14 petabytes was only the launch pad.
By 2026, after adding Redfin and Mr. Cooper, Rocket was reporting more than 30 petabytes of data, enough to fill more than 234,000 128-gigabyte iPhones. In a matter of months, Rocket’s reported data holdings had more than doubled. Rocket now says those 30-plus petabytes contain thousands of attributes used to establish client profiles, while insights from more than 160 million client calls annually help power its AI models.
When an analyst later asked why Rocket wanted Redfin, Krishna was even more direct: “We want to grow in purchase. We want to invest deeply in data and AI.”
Then he essentially described the thesis of this article himself:
“We really think of this as two data and tech companies sort of coming together.”
This isn’t a company quietly accumulating data as a byproduct of doing business.
Data is driving the business. And Rocket has been remarkably explicit about where Redfin’s consumers fit into it.
Krishna has repeatedly described Redfin’s nearly 50 million monthly visitors as the “top of the funnel.” By May 2026, he was laying out the entire chain: Redfin provides “the intent” at the top of the funnel, Rocket Mortgage provides the financing, and Mr. Cooper provides the ongoing servicing relationship. Together, he said, they create a “proprietary dataset across the entirety of the homeownership life cycle.”
That makes Redfin’s visitors funnel fodder.
Redfin Wants To Know You… Really Well.
This brings to mind another oft-repeated phrase: “To know you is to love you.” In 2026, it may be closer to “to know you is to monetize you.”
Redfin’s privacy policy says it collects the kinds of information most of us have come to expect websites to collect: browsing and search history, properties viewed or saved, device information and geolocation where permitted. Standard stuff.
But California residents get a more detailed version. Why? Because California has some of the country’s most stringent consumer-data disclosure requirements. Companies must identify specific categories of personal information they collect, which means Redfin has to tell Californians considerably more about the information it collects and the inferences it may make from it. Let’s take a peek at that disclosure, shall we?
Redfin identifies a category called “inferences,” which can reflect a consumer’s “preferences, characteristics, psychological trends, predispositions, behavior, attitudes, intelligence, abilities, and aptitudes.”
This doesn’t mean Redfin has built a CIA-level profile on you because you admired photos of a Tudor in Cleveland Park, but it does mean that browsing a real estate portal can generate something far more commercially valuable than the list of houses you viewed, and that you might not know about it.
Patterns reveal intent.
A consumer can begin as a casual browser and gradually behave more like a buyer. Searches can become more frequent. Geography can narrow. Price ranges can change. Property types can change. Favorites accumulate.
And Rocket’s CEO has already identified the prize: Redfin encounters people months before they ever talk to a lender, need an agent, title insurance, HO-6 insurance, or a valve replacement for their Land Rover.
That’s an extraordinarily valuable place to meet funnel fodder.
The Houses Are What Bring Us There
None of this works without listings.
No listings, no buyers and sellers searching. Period.
That’s why the industry’s recent battle over private listings was much more than an argument about how houses should be marketed.
Real estate portals depend on inventory they largely don’t create. Brokerages and their agents acquire the listings. Sellers own the properties and, subject to applicable law and contractual obligations, make decisions about how their homes will be marketed.
The portals need those homes because the homes bring the consumers.
Redfin initially aligned itself with Zillow’s push against privately marketed inventory. But by 2026, its approach to differentiated and pre-market inventory had changed considerably.
Its new Early Access program gives certain listings premium placement before they receive broader exposure. They don’t accrue days on market or publicly display price-drop history during Early Access. Consumers can connect directly with the listing agent. Redfin tells sellers they can test pricing and demand before broad exposure without accumulating the digital baggage that can hurt a listing when it finally hits the public market.
That’s quite a change.
It’s also smart.
Redfin gets differentiated inventory that gives consumers another reason to search Redfin rather than assume every portal offers exactly the same thing.
And Rocket gets the consumers who come looking for those houses.

The economics are remarkably easy to understand once you stop looking at Redfin simply as a brokerage.
And Rocket wants to analyze and monetize the consumer for life.
Rocket has repeatedly described nurturing consumers through personalized experiences until they’re ready for another transaction, while its filings link customer retention to client lifetime value. One Rocket/Mr. Cooper investor communication put the predictive ambition particularly neatly: “Our data signals tell us when it’s time to reach out, engage, and guide,” even before a home search begins.
Now put Redfin at the front of that system.
This Isn’t Just Real Estate Technology
For years, residential real estate operated in a shockingly obsolete digital environment. Many large brokerages provided little meaningful technology beyond the basics, leaving agents to cobble together their own CRMs, transaction-management systems, marketing platforms and other software, often contracting for and paying for those tools themselves.
That has changed dramatically. Technology-focused brokerages began integrating CRM, predictive tools, offer and contract preparation, transaction tracking, marketing and client-facing dashboards into the brokerage itself. Similar technology is now widely available to brokerages as packaged, adaptable or inherited systems. What seemed revolutionary less than a decade ago is increasingly becoming standard brokerage infrastructure.
Those systems use data, too. They can help an agent identify which existing contacts may be approaching another transaction, organize a client relationship and manage a sale from prospect through closing. The technology is built principally around helping agents and clients conduct real estate transactions.
Rocket’s vision for Redfin is something else.
It isn’t simply using technology to modernize the work of a brokerage. Redfin puts Rocket in front of consumers months before many of them choose an agent or lender. Their behavior generates data. The data reveals intent. Intent generates leads across brokerage, mortgage, title, closing and servicing. Those relationships generate still more data, which Rocket says it wants to use to deepen AI, prediction and personalization and create additional products and services.
Traditional brokerage technology was built around the real estate transaction. Rocket is building transactions around the data.
An Invitation Can Become A Problem
The question isn’t what Rocket knows now. It’s what future Rocket may do with the information later.
There is another connection between Redfin and Meta that deserves attention.
In April 2026, California real estate broker Biljana Gallardo filed a proposed class action alleging that Redfin transmitted consumers’ property-video viewing activity and information from its mortgage prequalification process to Meta and TikTok without their consent. Her 37-page complaint alleges that Redfin embedded Meta and TikTok tracking pixels in its website and disclosed private video-consumption history along with answers consumers provided during the mortgage prequalification process, including information about credit-score ranges, home-purchase timelines and property preferences. The allegations haven’t been adjudicated.
That’s particularly relevant because the value Rocket itself assigns to Redfin is intent. A property viewed, a buying timeline, property preferences and some indication of financial capacity aren’t simply website analytics when assembled around an identifiable consumer. Together, they begin to describe a prospective homebuyer.
Gallardo’s isn’t the first lawsuit challenging Redfin’s tracking practices. In 2024, Guillermo Mata filed another proposed class action alleging that Redfin shared information about visitors’ website activity and guided-tour videos with third parties. The federal case was stayed pending individual arbitration, and Redfin’s own SEC filing says it settled Mata’s claim in January 2025. The company didn’t disclose the settlement terms in that filing, and the underlying allegations were never adjudicated.
Then came Sam Cacas in May 2026. He alleged that Redfin caused trackers and cookies to be installed on visitors’ browsers and used them to collect identifying information and numerous other data points revealing users’ behavior and activity. Redfin moved to compel individual arbitration. On July 30, a federal judge found that Redfin had established Cacas’s agreement to arbitrate, granted the motion and stayed the case pending arbitration. The court did not determine whether his underlying privacy allegations were true.
Nor does the issue stop at Redfin.
In January 2026, Gary Fedoroff filed a proposed class action against Rocket Mortgage after completing an online refinancing application. According to the federal court’s account of his complaint, Fedoroff supplied personal information and nonpublic financial information including his estimated home value, requested refinance amount, mortgage payment, homeowners insurance premium, property taxes and reason for refinancing. He alleges Rocket then disclosed information related to his mortgage application through tracking technologies embedded in its website. His complaint identifies Optimizely, which he alleges allowed Rocket to track and share details about a customer’s website visit, including actions taken and when they occurred.
In June, Rocket successfully moved to transfer Fedoroff’s case from California to Michigan under the forum-selection provision in its Terms of Use. The court enforced that provision and transferred the case without deciding whether Rocket had unlawfully disclosed Fedoroff’s information. The case continued in the Eastern District of Michigan.
None of these cases establishes that Rocket or Redfin engaged in unlawful conduct. But collectively, they make the consumer-data question considerably less theoretical.
A consumer thinks she’s looking at houses. Another thinks she’s answering questions to see whether she might qualify for a mortgage. Those interactions can generate information about identity, finances, preferences, behavior and intent.
And the information those activities produce may be valuable for something else entirely.
That’s the problem with an invitation that looks so simple.
“Come look at houses.”
Redfin gets consumers earlier than a traditional brokerage, mortgage lender or title company often would. Rocket has explicitly identified that early consumer intent as one of Redfin’s great attractions. Once the consumer enters the larger Rocket ecosystem, the relationship can extend through brokerage, mortgage, title, closing and servicing, generating still more information along the way.
Rocket says it wants to use its expanding data holdings to deepen AI, prediction and personalization. It describes the combined companies’ information as a proprietary dataset spanning the homeownership lifecycle.
There is nothing inherently improper about using data to make a service better. Consumers benefit every day from technology that remembers preferences, anticipates needs and eliminates friction.
The harder question is where that process eventually leads.
Transparency can tell Granny what the machine does today. Consent can authorize uses that exist today. Neither can tell her what tomorrow’s machine may discover yesterday’s data is good for.
That’s especially relevant with AI because the capabilities are changing faster than the information being accumulated. We don’t know what future technology will be able to infer from combinations of browsing behavior, property interests, financial information, transaction histories, servicing relationships and everything else collected along the way.
And that’s why Sanfilippo’s appointment is more than an interesting personnel decision.
Rocket already had an experienced real estate executive running Redfin’s brokerage operations. After reviewing more than 200 candidates for CEO, it chose an executive whose career has centered on data science, data engineering, user research and extracting insight from consumer behavior. He came from Meta’s Reality Labs, where technology developed during his tenure is now itself the subject of litigation alleging that Meta used consumers’ Facebook and Instagram photos for purposes they hadn’t authorized.
That doesn’t tell us what Sanfilippo will do at Redfin.
It tells us what expertise Rocket went looking for.
We don’t know what they’re building. But we know who’s building it, what Rocket says it wants the data to accomplish, and what was being built around its new CEO the last time.
So I’m not going to predict that Rocket will misuse the enormous consumer dataset it’s assembling. There is no evidence that it intends to.
But I’m also not willing to make the opposite prediction.
Why would we assume that a massive consumer dataset will never acquire uses its creators, or the consumers who supplied it, didn’t originally contemplate?
At some point, assuming that it won’t may require more faith than assuming that it will.
Granny only came to look at houses.
