Property portals are ‘built to mine you’
Thought leadership by Olivier Jauniaux Founder of NestLink
On 14 August, Providence Equity Partners announced it had agreed to acquire Hometrack from ZPG. Bloomberg confirmed the seller the same day. Terms were not disclosed, though Real Deals, citing a source close to the deal, put the valuation at around £600m.
If that passed you by, you are in excellent company. Hometrack has no television campaign, no app on anyone’s home screen and no opinion on whether your extension added value. It tells mortgage lenders what houses are worth, for 16 of the top 20 in the UK and, by its own account, all of the top 14 in the Netherlands.
Three weeks later, on 8 September, Zoopla published its 2025 accounts under a headline announcing that it had doubled its homeowner audience to over six million and returned to profitability. Those six million people are not customers in any sense that involves money. They have volunteered their address, confirmed they own the place, and asked to be told what it is worth.
They are the inventory.
Put the two announcements side by side and the shape of this industry becomes embarrassingly clear. The business that explains property to lenders has a named buyer and a reported price. The business that explains property to the public is still sitting in the window with a rumour attached to it. Same underlying facts. One of them got paid.
Nobody has actually announced anything about Zoopla
This needs saying plainly because the industry repeats the Zoopla sale as though someone confirmed it. Nobody has.
City AM claimed in April 2025 that Silver Lake had put a £500m tag on the portal, with no named source, traced back to a podcast. Sky News reported in September 2025 that JP Morgan and Arma Partners had been engaged to review options for ZPG, with a series of separate sale processes seen as the likeliest outcome. Zoopla’s only on-record position, then and now, is that the ZPG board regularly engages specialist advisers and that, for Zoopla, it is business as usual.
Every article about this says Silver Lake paid £2.2bn in 2018, so £500m is a catastrophe. That is not a comparison, it is a category error. The 2018 deal bought ZPG whole, including Uswitch, which was doing a great deal of the heavy lifting at the time. Uswitch and the comparison brands went into RVU with Red Ventures, Confused.com was bolted on in 2020, Alto was spun out last year, and Hometrack has now gone to Providence. Nobody outside Silver Lake knows what Zoopla alone was implicitly bought for, so nobody can tell you what has been lost or gained on it.
What is left in the Silver Lake shop window is the Zoopla portal, Alto CRM, and PrimeLocation. Revenue of £83.2m for 2025, down 1.1% on the year and down from £90.4m in 2023. Profit of £20.7m at a 16% margin, achieved substantially by taking staff headcount down from 483 to 388.
Q1 2026 revenue up 9%. Hold the rumoured £500m against that and a buyer is paying around six times sales and 24 times profit for a business with a shrinking top line. Either the number is wrong, which is perfectly possible given where it came from, or the future buyer is paying for something that is not the portal.
They Are Buying You
Zoopla has been admirably direct about this. It now describes itself as shifting from property portal to data-driven homeowner platform and has said publicly that pushing as many leads as possible irrespective of outcome is no longer the strategy.
Read that from the buyer’s chair. The chief executive of the country’s second largest portal is explaining that the portal is not the thing on sale. The audience is.
Divide the rumoured £500m by six million homeowners and you get roughly £80 a head for the real data on “intention to move”.
Somewhere in an investment data room there is a slide explaining that a homeowner who checks their value every few weeks is a seller who has not instructed yet, a remortgage that has not happened yet, and a buyer who has not started searching yet, all behind a single login, a registered address and contact info. That is the asset.
What do we get for our data?
A number.
That is the entire consideration.
In exchange for the most consequential financial fact about your household, the one that decides whether you sell, remortgage, extend or sit tight for another year, you receive an estimate with acknowledged limitations and, if you linger a bit too long on the page, a phone call from an estate agent.
Nobody tells you the lease has 79 years left and falls off a cliff at 80. Nobody flags the planning application two doors down, the flood map that was quietly redrawn, or why the EPC says D while the bills behave like an F.
All of that is knowable. Most of it is public. None of it arrives because the product was never built to inform you.
It was built to mine you.
Meanwhile the same underlying facts, dressed for a different audience, were worth a reported £600m to Providence. The model telling a lender your house is worth £480,000 and the estimate telling you your house is worth £480,000 are close cousins. One is sold into an underwriting process with versioning, accountability and a customer who can sue. The other is given away to keep you opening an app, with a disclaimer underneath.
The information asymmetry in the UK housing market is not an accident of technology. It is a pricing decision, and it was made a long time ago.
That is the gap NestLink’s KnowYourNest exists to close, and the difference is easy to state without a pitch. A valuation tracker treats an address as a lead with a countdown attached. We treat it as a decision somebody is about to make with their own money: the title, the lease, the risk, the planning, the condition, written so a human can act on it rather than forward it to a solicitor and hope.
Zoopla has already proved the demand at a scale no startup can argue with. Six million people will engage with a platform about their home long before they will engage with an agent. What they are handed in that window is a number and a sales call.
If a lender buys it, YOU get sold twice
Look at where Hometrack just went. The valuation infrastructure has been bought by a firm backing the digitisation of mortgage lending. Apply that logic to the Zoopla consumer brand and its six million homeowners quietly signalling their equity intentions, Zoopla stops being a portal provider and becomes a remortgage pipeline. The 16% listing margin becomes irrelevant, because the money is made somewhere else entirely.
At that point, any household that handed over an address for a free estimate has been sold twice, first as a lead and then as a customer, without being asked on either occasion.
