Joseph Lee, Founder & CEO, Supademo | Techstars Alum | Forbes 30 Under 30

👤 About Him

Some people wait for the right time. Joseph Lee started at 15.

He didn’t come from a roadmap. He created one — driven by curiosity, clarity, and courage. A Korean‑Canadian founder, product builder, and design thinker, Joseph has spent his life turning friction into flow.

For him, building isn’t just a job. It’s a mindset — one that blends product, design, growth, and leadership into something that actually moves people.

“I’ve been a builder since 15 — always optimizing for growth, learning, and impact. Entrepreneurship is how I channel all three.”

📖 From Zero to Something That Matters

Joseph’s early ventures weren’t glamorous. But they were real.
He learned fast. He failed faster. And he repeated that cycle until something clicked.

That something was Supademo — his latest company that’s now transforming how businesses onboard users, teach products, and close deals through interactive AI‑powered demos.

Before Supademo, he built Freshline, North America’s first demand-driven seafood marketplace that evolved into a B2B eCommerce platform — turning operational inefficiency into innovation.

But he doesn’t just talk product.
He talks about the lonely nights, the pivots, the rejection, the tenacity it takes to stay in the game when no one’s clapping yet.

🛠️ What He Built: Supademo

Joseph didn’t want to just improve onboarding.
He wanted to reimagine how people learn products.

So, he created Supademo — a no-code platform that lets anyone build step-by-step, click-through product demos in minutes. It’s like Loom + Figma + onboarding magic — powered by AI.

• 🧠 No coding
• 🛁 AI voiceovers, multi-language translation, smart annotations
• 📊 Analytics + sharing + embedding anywhere
• 🚀 Used by 15,000+ teams globally, including Netflix, Turo, Siemens, and more
• 🏆 Ranked #5 on G2’s Fastest-Growing Products

Supademo isn’t just a product. It’s a solution to friction — the kind of friction every startup faces when trying to explain what they do.

💡 Why His Journey Matters

Because Joseph didn’t just build a tool — he built trust.

He built in public.
He shared not just the wins, but the wrong turns.
He turned transparency into traction.

“I share unfiltered stories, tips, and tactics behind early-stage startups and entrepreneurship.” – 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.

🔥 What New Entrepreneurs Can Learn From Him

Here’s what Joseph teaches without saying a word:

• Start before you’re ready. Don’t wait for perfect. Build, ship, learn.
• Be honest. Transparency builds trust — in your product, your story, and your self.
• Solve real pain. Don’t chase hype — chase problems worth solving.
• Don’t be afraid to pivot. Reinvention is part of the journey, not a detour.
• Growth is not just a metric — it’s a mindset. Joseph is living proof that compound learning creates exponential results.
