Off the Yellow Brick Road

WHERE WE LEFT IT

Three arguments here over three weeks. CRE is two industries under one name, and AI hits each differently. The middle layer of PropTech is hollowing out as buyer-builders take it in-house. The consortium deals are a game mid-tier operators should refuse to imitate.

For years, CRE technology came from two places: a startup sold you software, or you built your own. The incumbents sat beneath both as the systems of record. AI has added two more players. The labs are taking the horizontal work directly. The consortia are taking the repeatable middle. Five kinds of player now compete across the same ground, and the only useful question is where each should stand.

A piece from Andreessen Horowitz, published the same week as the last of those three, gives us the map to answer it.

WHAT THE VC SIDE JUST SAID

Joe Schmidt, partner at a16z, published Avoiding Death on the Yellow Brick Road on 27 May. It is, in Roger Martin’s terms, a where-to-play map. The labs own the Yellow Brick Road: horizontal, low-step coworker work that improves with raw model capability. Everything else lives in the Rest of Oz: vertical, multi-step, regulated, judged on customer P&L rather than benchmarks. Both can win. Most application-layer startups will die because they walked onto the road.

The Rest of Oz survives the labs on four defences, Schmidt argues: data flywheels, model routing across vendors, cost optimisation across model tiers, and governance that absorbs regulatory complexity for the buyer. Three tests tell you whether you are on it. The tools-and-steps test: how many steps does the work take, and how complex are the tools beneath it? The system test: are you the system the customer runs work through, or a tool sitting on one they already have? The P&L test: are you judged on customer outcomes, or on benchmark scores?

Apply this to CRE and the diagnosis from the last three pieces survives intact. The middle layer of cognitive workflow software dies. Generic AI-for-X PropTech fails all three tests. As last week’s piece argued, the buyer becomes the builder where the work carries its proprietary edge. Schmidt adds the other half from the venture side: the startup wins where it owns the system of work, not where it wraps a tool around someone else’s system. Two people landing on one diagnosis from opposite ends of the industry is the closest thing to validation an argument like this gets. The three tests are also sharper than anything in the trilogy; use them on whatever you are buying or selling.

THREE TERRAINS, FIVE PLAYERS

Translate the map to CRE and there are three terrains, not two. The Yellow Brick Road carries generic coworker work. Between it and the deep country sits Mid-Oz: vertical-ish work, repeatable and configurable enough to standardise across firms. The deep Rest of Oz is the domain-specific, multi-step, regulated, judgement-heavy work that cannot be built from generic capability alone.

Now put the five players on that ground.

The labs own the Yellow Brick Road and reach into the edges of Mid-Oz. The consortia — Anthropic’s enterprise AI venture with Blackstone, Hellman & Friedman and Goldman Sachs, and OpenAI’s Deployment Company — are built to industrialise Mid-Oz, standardising repeatable workflows across the companies they deploy into. They have the capital to do it. They are not the only ones who can. The deep Rest of Oz belongs to two kinds of player: operators who build their own systems, and startups that own a single painful, regulated, commercially material process end to end and get better at it with every deployment. The incumbents sit beneath all of it, across the systems of record.

That is the where-to-play map. The two new entrants, labs and consortia, arrived with clear remits. The three players who were already here — incumbents, startups and operators — now have to relearn where their advantage lives. Take them in turn.

THE INCUMBENTS HAVE LOST THEIR FREE PASS

The first is the incumbents. Yardi, MRI, Argus, CoStar, MSCI/RCA hold the systems of record and the data primitive layer. Schmidt predicts they survive: whoever owns the system of work survives the labs. The position is theirs to lose, and it is defensible. They are also, on any fair read of their fifteen-year record, the firms in CRE least obviously equipped to execute on AI at speed.

That did not matter before. They were unassailable. Switching costs measured in years, certifications in decades, relationships in golf-course-time. They did not need to be good at innovation because nothing they did was contestable. Argus has long been the sector’s byword for standing still. None of these firms has been a natural home for ambitious AI talent. None of it cost them their position.

It does now. The position has not become indefensible; the cost of defending it has gone up. While still unlikely, it is no longer impossible that an embedded operating system gets supplanted, worked around, or abstracted away from being critical. The three challenger paths I named last week — operator-spinout architectures, specialist services-as-software vendors, and lateral entries on incumbent failure points — can each take meaningful share without dislodging the incumbent outright. None of those routes had credible AI-driven economics eighteen months ago. All of them do now.

So the incumbents win this round by default, and have to play the next one properly. The free pass on execution and innovation is the thing that has changed. Should win is carrying real weight in that phrase. Whether they will is no longer the irrelevant question it has been for fifteen years.

THE EASY STARTUP IS DEAD

The second is the startup, the player Schmidt is really writing about and the one whose ground has moved most. His argument is widely misread as “the labs kill startups”. It is narrower. The labs kill the lazy startup. A model wrapper, a reporting overlay, a generic AI-for-real-estate copilot on someone else’s system: the road absorbs all of them.

The startup that survives owns a system of work. It takes one painful, multi-step, commercially material CRE process and becomes the place that process happens, capturing the workflow data, the governance and the record of what was done. It picks ground where the incumbent is too slow to follow, the operator cannot justify building alone, and the labs cannot learn the domain from outside. And it gets better at that one thing with every deployment, which is the one moat Schmidt thinks survives contact with the labs.

That is a narrower opening than PropTech has enjoyed for a decade. It is also a more defensible one. The winning CRE startup will not sell AI into the industry. It will take a slice of the industry’s work and own it end to end.

THE OPERATOR DEFAULT IS DATED

The third is the operators. The default setting for almost every CRE operator today is buy. That setting is rational. It is also dated.

When sophisticated operators made their AI decisions through 2024 and 2025, the build path was not credibly open to a mid-tier firm. Agentic infrastructure was immature. Models could not yet do agentic work reliably enough for a mid-tier firm to bet on them. Skills frameworks barely existed. Forward-deployed engineering for mid-market operators barely existed. Buying from an incumbent or a specialist vendor with the infrastructure already in place was the right call.

It is a different call today, and will be different again in 2027. AI capability is improving fast enough that any tooling commitment is now a bet on which curve is steeper: the buy partner’s incremental AI delivery, or the operator’s own build option as the underlying tools become generally available.

Sam Altman has made this point to founders for years. Build assuming the models keep getting better, not assuming they stay still. He reckons 95% of founders should bet on continued improvement; most bet the other way and end up as the “OpenAI killed my startup” meme. The advice travels to a sophisticated CRE operator unchanged. What is impossible to build in-house this year may be routine next year. The work an operator treats as its distinctive edge may be buildable in-house the year after.

None of this says build everything, or that buying today is wrong. It says the buy decision now needs making with one eye on whether what you are buying is still the right thing across the life of the commitment.

For now, an operator’s tacit knowledge is proprietary. The consortia are the most visible mechanism that changes it. Forward-deployed engineers embedded across enough client firms observe how each one operates, then aggregate what they see into a standardised method the whole industry can buy. Every deployment makes the next operator’s edge a little less distinctive. The window between proprietary and commoditised is open now, and the cost of building tools to capture your knowledge in your own systems before it shuts is falling fast.

DIRECTION OF TRAVEL

Put the map and the three moving positions together, and the takeaway is easy to state and uncomfortable to act on.

The field has five players now, not the two it had when the only question was build or buy. The labs own the road. The consortia are industrialising the middle. The incumbents hold the systems of record but have lost the free pass that let them coast. Operators and startups contest the deep country, where the real systems of work get built.

So the question is not whether AI changes your corner of CRE. It is which of the five you are, and where on this ground you can win. Most of the industry will treat that as too early to act on. By the time they do not, the positions will have been taken.

The Wizard is buying road. The land is shifting faster than the road is being laid.
