Yesterday, Sam Altman, CEO of OpenAI, sent a ripple across the tech world with a single Tweet

In it, he hinted that the SaaS industry may be entering its "fast fashion" era, where apps are built faster, cost less, and become obsolete quicker than ever

This isn’t just a change. It’s a warning shot

AI is fundamentally reshaping how software is developed and delivered

What used to take months or years to build can now be prototyped, tested, and deployed in days

With lower barriers to entry and faster product lifecycles, the very foundation of the SaaS model is being challenged

Forget the MarTech 10,000—we’re heading toward MarTech disposable

Analysts believe we’ll soon move from subscription-based models to outcome-based services

In short, customers won’t pay for platforms, they’ll pay for results

And with AI embedded deeply in every part of the stack, the value will come not from the tool itself, but from what it does in real time

So what now?

The smart SaaS founders will cash out early

The savvy VCs will look to cut their losses, refocus capital, or accelerate M&A

And the market? Expect rapid consolidation, and a graveyard of logos

Conclusion:
The software landscape is being rewritten by AI

Those clinging to the old SaaS playbook will be left behind

Those who adapt, fast, might just survive the shakeout

One thing is clear: the game has changed

And Sam Altman just called the opening move
