How AI Forces SaaS Founders to Rethink Product-Market Fit

by | Apr 6, 2026

When your market shifts and your product changes with AI, your product-market fit is changing.

Existing categories of software are evolving (CRM) and new categories are showing up (AI legal software).

Customer segments that were dormant are now active, now that AI can handle much of the work they previously avoided.

Your new product features and efficiencies open up new customer segments you didn’t reach before.

Are you adjusting your product and your market to create new fits with your new AI features and apps?

Joseph Lee is the co-founder and CEO of Supademo, a fast-growing SaaS company that solves a common pain point: quickly creating new product demos.

In just 2.5 years, they built a modern, AI-powered solution that dramatically simplifies how teams showcase software.

Supademo has reached $3M in ARR in 2.5 years and is growing at more than 100% annually under a freemium model.

The product enables teams to create interactive, annotated, and even translated demos in minutes instead of days or weeks.

The freemium model, reverse trial onboarding, and viral product loops have driven strong PLG growth, while enterprise demand is now emerging as a second growth engine.

Joseph is a second-time founder with global experience spanning Korea, Vancouver, and New York.

He’s raised a small amount of capital but is focused on practical execution.

Supademo is winning and growing fast by trying things fast and shipping fast.

Not getting stuck in old PMF boundaries and not counting on marketing or sales tactics to stay the same.

“There’s no bread and butter GTM channel that is going to work permanently into the future. And the biggest lesson I take away is that product-market fit nowadays has a finite shelf life.

“You have to constantly reinvent yourself and be paranoid, because the market is changing, new competition is coming, and the dynamics are changing. You can’t rest on your laurels; you have to be constantly innovating, like at a faster pace than ever before.

“Our team’s competitive advantage is the ability to move quickly and ship quickly. It’s combining gut-based on our intel and context of the industry and tribal knowledge with some data to act faster than anyone else. Not analysis paralysis or having everything planned out. Just shipping something that may be imperfect, but using that as leverage to learn quickly and iterate quickly.”
