Joseph Lee, Founder & CEO, Supademo | Techstars Alum | Forbes 30 Under 30
π€ About Him
Some people wait for the right time. Joseph Lee started at 15.
He didnβt come from a roadmap. He created one β driven by curiosity, clarity, and courage. A KoreanβCanadian founder, product builder, and design thinker, Joseph has spent his life turning friction into flow.
For him, building isnβt just a job. Itβs a mindset β one that blends product, design, growth, and leadership into something that actually moves people.
βIβve been a builder since 15 β always optimizing for growth, learning, and impact. Entrepreneurship is how I channel all three.β
π From Zero to Something That Matters
Josephβs early ventures werenβt glamorous. But they were real.
He learned fast. He failed faster. And he repeated that cycle until something clicked.
That something was Supademo β his latest company thatβs now transforming how businesses onboard users, teach products, and close deals through interactive AIβpowered demos.
Before Supademo, he built Freshline, North America’s first demand-driven seafood marketplace that evolved into a B2B eCommerce platform β turning operational inefficiency into innovation.
But he doesnβt just talk product.
He talks about the lonely nights, the pivots, the rejection, the tenacity it takes to stay in the game when no oneβs clapping yet.
π οΈ What He Built: Supademo
Joseph didnβt want to just improve onboarding.
He wanted to reimagine how people learn products.
So, he created Supademo β a no-code platform that lets anyone build step-by-step, click-through product demos in minutes. Itβs like Loom + Figma + onboarding magic β powered by AI.
- π§ No coding
- π AI voiceovers, multi-language translation, smart annotations
- π Analytics + sharing + embedding anywhere
- π Used by 15,000+ teams globally, including Netflix, Turo, Siemens, and more
- π Ranked #5 on G2βs Fastest-Growing Products
Supademo isnβt just a product. Itβs a solution to friction β the kind of friction every startup faces when trying to explain what they do.
π‘ Why His Journey Matters
Because Joseph didnβt just build a tool β he built trust.
He built in public.
He shared not just the wins, but the wrong turns.
He turned transparency into traction.
βI share unfiltered stories, tips, and tactics behind early-stage startups and entrepreneurship.β – Joseph
He knows that someone out there is struggling through the same chaos he once did.
And instead of gatekeeping the answers, he gives them away.
π₯ What New Entrepreneurs Can Learn From Him
Hereβs what Joseph teaches without saying a word:
- Start before you’re ready. Donβt wait for perfect. Build, ship, learn.
- Be honest. Transparency builds trust β in your product, your story, and your self.
- Solve real pain. Donβt chase hype β chase problems worth solving.
- Donβt be afraid to pivot. Reinvention is part of the journey, not a detour.
- Growth is not just a metric β it’s a mindset. Joseph is living proof that compound learning creates exponential results.
