Your SaaS vendors are your landlords. Stop paying rent.

Microsoft, Google, Salesforce, Snowflake, Oracle, SAP. Every one of them is a landlord. You pay them monthly rent to use software that, in most cases, is either commoditized, replaceable with open source at 1% of the cost, or actively declining in relevance. And right now, every one of them is racing to lock you into their AI platforms before you realize you don’t need them anymore.

The tools they sell are either being used less and less (Word), no longer meaningful (Salesforce’s UI), or have free alternatives that do the same job (Mattermost vs. Slack). The “platforms” they’ve built on top, the ones they charge you to customize, require specialized developers who cost as much as the ones who could build you something better from scratch. And now they want to extend that model to AI agents, charging you per-seat licenses for intelligence that runs on their infrastructure instead of yours.

Everything these platforms offer can be built bespoke for your company’s actual value chain. One or two developers can build enterprise applications in weeks. The only real cost is a model provider, and if you’re serious, open-weight models on your own hardware eliminate even that. A rack in a data center, a fiber connection, free databases, free frameworks, free packages.

The entire SaaS economy is a rent collection scheme for problems that no longer require landlords.

The CIOs who continue shoveling money to these vendors are operating on outdated assumptions. Most of them are vendor managers and help desk managers in an archaic model that can’t survive past this year.

The companies that keep hitching their wagons to tech behemoths looking to defend quarterly revenue are funding their own obsolescence.

And conservative industries like healthcare, the ones least likely to see it coming, will be blindsided by lean AI-native competitors who accomplish the same outcomes with a fraction of the staff and zero vendor dependency.

There is no greater sense of urgency in the history of business than right now. Companies can decouple from their dozens of landlords, reimagine their operations, and reengineer themselves with minimal resources, minimal time, and minimal risk. The real risk is old thinking.

The numbers your vendors hope you never add up

Most executives know their contract totals. Almost none know their real SaaS spend.

The average enterprise runs 112 SaaS applications. Annual cost per employee lands between $9,000 and $17,000. Microsoft is raising prices 9-33% in July. And those are just the subscription line items.

They don’t account for the implementation consultants. The integration middleware. The dedicated admins. The customization projects that run 200% over budget. The premium support contracts that add 30% on top of the license.

Salesforce is the clearest example. The license is the door fee. True total cost of ownership runs 40-80% above the sticker price once you factor in implementation, customization, a full-time admin earning $70,000 to $110,000, and the AppExchange add-ons required to make it do what you actually wanted in the first place. You’re paying for the building, the renovations, the maintenance staff, and the property manager. At the end of every year, you own nothing. The landlord keeps the equity.

Now consider what that same money could build if you owned instead of rented. A single senior developer with AI tooling costs less annually than most enterprises spend on one vendor’s ecosystem. The applications they produce fit your business exactly. They run on your infrastructure. They improve every month because they were designed for your value chain, not abstracted across 10,000 customers. And they’re yours. The hard part isn’t the technology. It’s finding someone who can see your business clearly enough to architect it.

The lock-in is the product

The vendors understand this math. That’s why they’re not competing on capability anymore. They’re competing on dependency.

Microsoft’s rumored E7 tier is the most transparent example. $99 per user per month. AI agent licensing bundled into your enterprise subscription. Your agents get identities, email accounts, Teams access, policy controls. Microsoft wants you to build your AI workforce inside their walls so that leaving means dismantling the workforce itself.

This is the same model they’ve run for three decades, extended to machines. Except the switching costs for AI agents embedded in your workflows will be even higher than the switching costs for the productivity tools they replaced. That’s the point. The cage gets bigger, not smaller.

Salesforce is doing the same thing with Agentforce. Google with Gemini in Workspace. They watched $1 trillion disappear from software stocks in four weeks and understood what it meant. The per-seat model is dying. Their response is to move the lock-in upstream, from the application layer to the intelligence layer, before their customers realize the cage door was never actually locked.

The CIO question

Here’s the part that makes people uncomfortable.

I’ve spent 20 years working inside multi-billion dollar organizations. The CIOs I’ve worked alongside are sharp operators. But the role was never designed to require building technology from scratch. It was designed around selecting, procuring, and managing it. That distinction didn’t matter when building was impractical. It matters now.

The role, as practiced in most enterprises, is about managing vendor relationships and keeping the lights on. Negotiating enterprise agreements. Running procurement cycles. Overseeing help desks. These are the skills the job selected for over the past two decades, because buying was the only practical option and managing what you bought was the entire job.

That was a perfectly valid role when building was expensive and buying was efficient.

Both of those assumptions expired.

The CIO your company needs in 2026 is an architect. An orchestra conductor who can look at the entire value chain and see where purchased software can be replaced by owned intelligence. Who understands that the $50 million spent annually on SaaS isn’t a cost of doing business. It’s a choice. And increasingly, it’s the wrong one.

The CIOs who keep renewing contracts, adding Copilot licenses, and telling the board they’re “leveraging AI” while changing nothing about the fundamental architecture are doing what feels safe. It’s the most dangerous thing they could do. They’re playing the role that Blockbuster’s management played in 2005, defending a model that’s already been repriced by everyone outside the building.

Conservative industries will be hit hardest

Healthcare will be last to figure this out and first to pay for it.

Massive IT budgets. Deep vendor entrenchment. Regulatory complexity used as a reason to avoid change for decades. The same playbook that kept Epic, Cerner, and a dozen middleware companies embedded in health systems long past the point where better alternatives existed.

But 85% of generative AI spending in healthcare is already flowing to startups, not incumbents. Even in segments where Microsoft’s Nuance had decades of market presence, new entrants are winning.

Somewhere right now, a startup with 15 people is building an AI-native version of what took a health system 2,000 employees and $200 million in annual IT spend to operate. Healthcare’s regulatory moat is thinner than its leaders believe. And the pattern is universal. Incumbents protect existing revenue until a structurally different competitor makes the revenue irrelevant. Blockbuster. Kodak. The difference this time is the timeline. Two to three years of compressed disruption, not a decade of gradual decline.

What decoupling actually looks like

Shopify’s CEO told his entire company: before requesting additional headcount, demonstrate that AI cannot do the job first. A $100 billion company where “prove the machine can’t do it” is the default hiring policy.

Apply the same standard to your vendor stack. Before renewing a contract, demonstrate that the software cannot be replaced with something you build and own. Run a real evaluation, done by people who understand both the business and the technology well enough to see what’s actually possible now. Most companies will be shocked at the answer.

Decoupling doesn’t mean ripping everything out overnight. It means looking at every vendor relationship and asking two questions: Does this add genuine, irreplaceable value? Or does it exist because someone signed a contract six years ago and nobody’s questioned it since?

The companies that do this first will operate at fundamentally different economics. Lower cost structures. Faster iteration. Systems that fit their actual business instead of forcing their business to fit the system. Owned infrastructure that compounds in value instead of rented software that compounds in cost.

There has never been more urgency to rethink how your business is built. Not how it’s tooled. How it’s built.

The work is rebuilding the stack around intelligence. Mapping the value chain to technology you own. Every piece that matters, controlled by you.
