From Side Project to Scaling Ethereum: The Underdog Story of Polygon

“Just one laptop and an internet connection.”
That’s all JD, co-founder of Polygon, says you need to build in Web3. It’s not just a statement, it’s the philosophy behind one of the most successful blockchain scaling solutions today.

In a recent episode of Web3 Unlocked, hosted by Kenzie Wang and sponsored by Symbolic Capital, JD opened up about his journey from a small village in India to co-founding a billion-dollar Layer 2 blockchain that helps scale Ethereum. This is more than a tech origin story; it’s a masterclass in grit, luck, and relentless shipping.

A Different Kind of Opportunity

JD’s journey didn’t begin with privilege. His father was a factory worker, and JD grew up with limited access to education and technology. “My dad didn’t even know where my school was,” he says.

Despite the odds, JD chose engineering for a simple reason: it was the fastest path to earning a living. He eventually landed in IT, not out of passion, but because it was the only course he could get. He didn’t even own a laptop until his second or third year of college.

Still, he found himself drawn to creativity, filmmaking, storytelling, and ideas. It was this curiosity that led him to create a Game of Thrones fan site where users could bet on fan theories. But integrating payments was a nightmare. That’s when he stumbled upon Bitcoin, and everything changed.

Falling Into Crypto, Climbing Toward Polygon

What started as a side project led JD into the crypto rabbit hole. He began experimenting with Ethereum and realized the importance of scalability. “People were building,” he says, “but the tech was too complex, and it didn’t scale.”

JD didn’t just spot the problem; he set out to solve it. In a co-working space in Mumbai, he met Anurag, who became one of Polygon’s co-founders. Soon after, they connected with Sandeep, and together, they formed what would become the founding trio of Polygon.

But it wasn’t easy.

“No one believed in us,” JD recalls. “We weren’t from Stanford. We weren’t in Silicon Valley. We barely raised $600K when competitors were raising $50 million or more.”

Yet while their competitors never shipped, Polygon did.

The Secret Sauce: Shipping + Hustling

JD attributes Polygon’s success to three core capabilities: building, marketing, and ideation. He and his co-founders are what he calls “ambidextrous”; each of them can code, sell, and strategize. This flexibility allowed them to move fast, iterate, and talk directly to users, a practice they still maintain today.

“The secret? We replied to every dev, every project,” JD says. “Even now, you ping someone from Polygon, we’ll reply. That’s how we got 50,000+ dApps.”

This founder’s hustle extended to partnerships too. JD recalls cold emailing Decentraland, which led to one of Polygon’s earliest integrations. Other strategic partnerships, like with Starbucks and Instagram, brought Web2 users into the Web3 world and opened the door for mainstream adoption.

Why ZK Matters — and What’s Next

One of Polygon’s biggest bets was on zero-knowledge proofs (ZK), a more secure, scalable alternative to optimistic rollups. It was a risky, computationally heavy move, but one that paid off. Polygon became the first to ship ZK rollups in production before others could finish their optimistic designs.

Today, JD says, the technology is no longer the bottleneck; adoption is.

“We need that one killer app that brings millions into Web3,” he says. “And we need developers who build for users, not for quick NFT flips.”

To encourage that, Polygon continues investing in developer experience, grants, and infrastructure. And as JD hints, big governance changes and a redesigned token model may be coming, though he didn’t reveal details just yet.

Lessons for Web3 Founders

If there’s a single takeaway from JD’s story, it’s this: Keep building. Whether you’re in a village in India or a dorm room in Berlin, Web3 doesn’t care where you’re from, only what you build.

And when asked what makes a Web3 founder successful, JD doesn’t hesitate:

• Build fast.
• Sell smart.
• Think long-term.

“There’s no playbook,” he says. “You try 10,000 things, one works. That’s the strategy.”

Final Word

JD’s story isn’t just about Polygon. It’s about what’s possible when you don’t fit the mold, but still choose to build anyway. It’s about finding your co-founders in a co-working space, cold-emailing your way into partnerships, and surviving with just a couple of months of runway. And it’s about doing all that without ever getting burnt out.

“It was more fun when we had no money,” JD laughs. “We had nothing to lose.”

Maybe that’s the spirit of Web3, where the underdogs, the outsiders, the builders, rise.
