#190: Building Faster with AI-Powered Product Demos That Convert – Joseph Lee

Apr 2, 2026

Joseph Lee is the co-founder and CEO of Supademo, a fast-growing SaaS company solving a common pain: quickly creating new product demos. In just two and a half years, they built a modern, AI-powered solution that dramatically simplifies how teams showcase software.

Supademo has reached $3M ARR in 2.5 years and is growing more than 100% annually with 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 from Korea to Vancouver to New York. He’s raised a small amount of capital but is focused on practical execution. His approach reflects the broader shift of using AI to solve real workflow bottlenecks and grow efficiently without heavy funding.

Key Takeaways

  • Speed Wins – Reducing demo creation from weeks to minutes unlocks more usage, faster iteration, and better customer understanding
  • Do The Work – Early traction came from building demos for prospects manually, removing friction and proving value instantly
  • Reverse Trials – With free plans drive high conversion by letting users experience full value before choosing a plan
  • PLG + Enterprise – Bottom-up growth creates stability, while enterprise deals add larger revenue but less predictability
  • Constant Reinvention – Product-market fit is temporary in AI—founders must ship fast, iterate weekly, and stay paranoid

Quote from Joseph Lee, Co-founder and CEO of Supademo

“There’s no bread and butter GTM channel that is going to work permanently into the future. And the biggest learning that I took away was product market fit nowadays has a finite stamp when it comes to a period of time that it’s valid for. 

“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 got to be constantly innovating, like at a faster pace than ever before.

“Our team 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.”
