Is the ‘SaaSpocalypse’ a myth? The real cost of AI-built software

The business move

Some executives expect AI to trigger a ‘SaaSpocalypse’ where internal AI-built software replaces big SaaS platforms, slashing subscription fees. The idea is that companies can avoid paying for off-the-shelf software by building and customizing AI tools in-house. But the reality is more complex. The focus on upfront development cost misses ongoing expenses that can erode any savings.

Why it matters

Building AI-powered apps is not the end of the cost story. Running those tools requires continuous maintenance, security updates, compliance checks, and feature enhancements. These operational burdens fall on existing IT teams who often lack the capacity or domain expertise to sustain complex AI systems. Over time, the hidden cost of keeping AI tools reliable and safe can outweigh the initial savings from cutting SaaS subscriptions.

SaaS vendors embed decades of operational experience, security protocols, and compliance certifications in their products. When companies replace those with internally built AI systems, they take on responsibilities SaaS providers usually absorb. This shift tightens pressure on internal teams and raises risk. A cheaper development spend can lead to higher long-term operational overhead, slower innovation, and potential security gaps.

Who gains and who gets squeezed

AI benefits businesses that adopt it smartly, balancing build-versus-buy decisions. Companies with mature AI and software operations may succeed in maintaining custom AI tools, gaining more control and tailored features. Smaller companies or those lacking deep AI expertise face squeezed resources and risk being pulled into costly fire drills around maintenance and security.

SaaS vendors lose some price pressure but gain because buyers must assess ongoing total cost of ownership more prudently. Investors and operators will watch whether internal AI initiatives sustain value or turn into long-term drains on resources, slowing growth and innovation.

What to watch next

Keep an eye on companies publicly sharing their AI adoption cost structures, especially how internal AI buildout impacts operations teams and budgets over multiple years. Vendor responses will also matter as SaaS providers bundle AI features and emphasize end-to-end service reliability to justify ongoing subscription fees.

The real test is how many organizations can build AI tools internally without sacrificing velocity, security, or operational resilience. The touted ‘SaaSpocalypse’ may be more myth than reality without a full reckoning of what it takes to own AI software for the long haul.
