There is a real shift happening in software right now.

For the first time in a long time, a lot of people inside companies genuinely believe they can build software themselves. And to be fair, they are not hallucinating. With today’s AI tooling, developers really can ship prototypes, workflows, interfaces, and automations at a pace that would have felt absurd only a short time ago.

The productivity jump is real.

The feeling is real too.

For many teams, it feels almost magical.

That is exactly why the current moment is so dangerous.

Because when people see how quickly something can be built, they often confuse “we can build a version of it” with “we should build it ourselves.” (more to this later in the article)

That is the mistake.

And it is one of the clearest examples of how AI hype can lead smart companies into dumb decisions.

The Wrong Conclusion: “SaaS Is Dead”

One of the popular narratives circulating right now is that software-as-a-service is dying.

The argument usually goes something like this:

AI tools can now generate software.
Developers can move ten times faster.
So why would companies still buy SaaS products?

But this conclusion misses the point entirely.

SaaS is not disappearing. In many categories, it will remain the rational choice for a very long time.

What is changing is something else:

• the speed of software creation

• the shape of interfaces

• the expectations users have toward products

Those are real shifts.

But they do not mean every company should suddenly become its own software vendor.

In many cases, they mean the opposite.

Companies need to think more clearly about where their engineering resources create real strategic value.

And for most organizations, that is not in rebuilding tools they could simply buy.

The Seductive Part of AI Development

What AI has changed most dramatically is the first mile of building software.

A developer can now create:

• a rough workflow

• a clean interface

• a proof of concept

• a usable internal tool

• a prototype that demos extremely well

And when teams see that prototype, the reaction is often predictable:

"Wow. We could just build this ourselves."

That is the moment where the hype begins.

Because the first version is the seductive part.

It is visible.

It is demo-able.

It is exciting.

What people do not see is everything that comes after.

They do not see:

• the maintenance

• the integration logic

• the constant dependency updates

• the edge cases

• the reliability work

• the user feedback loops

• the operational support

A prototype is easy to celebrate.

A product is much harder to live with.

The Slack Example

One of the best ways to illustrate this is Slack.

In theory, many technical teams could build something that looks like Slack. There are open-source chat tools. The interface is not mysterious. The basic functionality is not rocket science.

So why does not every company simply build its own Slack?

Because the interface is not the product.

The product is everything around it:

• reliability

• integrations

• performance

• updates

• security

• usability

• support

• cross-team adoption

Thousands of invisible decisions make software usable day after day.

And that is exactly where the current AI hype creates confusion.

AI tools make it easier to generate software.

They do not magically eliminate the operational burden of owning software.

The Hidden Cost of “We’ll Build It Ourselves”

A team can absolutely build an impressive internal tool over a weekend.

But the real test comes later.

What happens when:

• an integration breaks

• a dependency changes

• an API updates

• the system fails during a critical workflow

• nobody remembers how the logic works anymore

Suddenly the excitement disappears.

And someone now owns a system that must be maintained indefinitely.

This is why the real cost of internal software is not the build.

The real cost is the life of the product after the build.

Which is precisely the problem SaaS companies solve.

Where AI Actually Creates Leverage

If AI truly makes developers three to ten times more productive in certain contexts, then the most exciting implication is not that companies can rebuild every internal tool.

The exciting implication is that companies can move faster on their own product vision.

They can:

• ship more features

• experiment faster

• innovate inside their category

• differentiate from competitors

• bring more value to market

That is where the leverage is.

Small and mid-sized product companies should not look at this moment and think:

"Great, now we can rebuild the tools we subscribe to."

They should think:

"Great, now we can build our future faster."

Those are very different mindsets.

One is operational.

The other is strategic.

AI Software Is Becoming More Complex — Not Less

Another misunderstanding in the current debate is that AI somehow simplifies software.

In reality, the opposite is often true.

AI systems introduce:

• model management

• evaluation logic

• prompt engineering

• reliability monitoring

• security concerns

• data pipelines

All of that adds complexity.

Which is exactly why specialized SaaS products continue to make sense.

For example, take the rise of AI coaching tools in business environments.

An organization could theoretically try to build an internal AI coach or AI sales coach using language models. But turning that into something reliable that actually improves sales performance is a completely different challenge.

A real AI coaching platform has to combine:

• learning content

• skill models

• behavioral data

• feedback systems

• integrations with sales tools

• continuous improvement loops

The difference between a demo and a production system becomes very clear.

This is why categories like AI sales software, AI sales tools, or AI tutor platforms are emerging as specialized SaaS solutions.

They package complexity into something organizations can actually use.

The Risk of Fragmentation

There is another reason leaders should be careful with the “build everything internally” instinct.

Internal build decisions are often made in moments of excitement rather than discipline.

A developer wants to explore a new capability.

Someone builds an agent.

Another team builds a different workflow.

Another builds a small automation.

Soon the organization ends up with:

• multiple tools

• multiple logic layers

• unclear ownership

• inconsistent outputs

What initially looked like empowerment slowly turns into chaos.

What the company ends up with is not a platform.

It is organizational debt.

SaaS Companies Absorb Complexity

A good SaaS company performs a specific role in the ecosystem.

It absorbs complexity so customers do not have to.

It takes fragile workflows and turns them into reliable systems.

It turns experiments into products.

It maintains integrations.

It supports users.

It iterates based on thousands of real-world interactions.

This applies to traditional SaaS products just as much as it does to emerging AI-powered tools like:

• AI sales coaching platforms

• AI tutors for training and enablement

• AI sales assistants

• AI sales tools embedded in modern sales tech stacks

These products exist precisely because maintaining them internally would be a distraction for most companies.

The Strategic Test

There is a simple test leaders can apply when deciding whether to build or buy.

Ask one question:

Does building this internally strengthen our unique product vision?

Or are we simply rebuilding something we could already buy?

If it strengthens the company’s unique offering, building might make sense.

If it replaces an existing category — messaging tools, CRM extensions, learning systems, AI sales coaching software — it is usually a distraction disguised as innovation.

The Real Risk of the AI Moment

The real risk of this moment is not that software-as-a-service disappears.

The real risk is that companies confuse technical possibility with strategic wisdom.

AI absolutely changes how software gets built.

But it does not remove the need for software providers.

If anything, as software becomes more complex, more integrated, and more AI-driven, the value of specialized platforms increases.

The winners in this next phase will not be the companies that rebuild every tool around them.

They will be the companies that use the new speed of software development to move faster on what only they can uniquely become.

That is where engineering energy should go.

Not on copying suppliers.

On building the future of the company itself.
