Meet Dr. Arokiaswamy Velumani: The Indian billionaire who studied on railway platforms while his mother earned Rs 3 a day

Some lives read like movie scripts. You know the kind - broke kid, impossible odds, crazy hustle, and then boom, an empire. Dr. Arokiaswamy Velumani’s story is one of those rare ones that’s actually real. No background music. No shortcuts. Just years of stubborn hard work and a lot of showing up when life made it really uncomfortable.

So, who is Dr. Arokiaswamy Velumani?

He’s the man behind Thyrocare Technologies, one of India’s biggest names in diagnostic and preventive healthcare. But he didn’t start with money, connections, or comfort. He grew up in a tiny village near Coimbatore in Tamil Nadu, in a family that barely scraped by. His father didn’t own land. His mother sold milk to keep the house running. Some days, that’s all there was.

College wasn’t easy either. Private colleges were way out of reach. The fees and hostel charges were more than his family could dream of paying. So he picked Sri Ramakrishna Mission Vidyalaya because it was cheaper, even though it meant travelling 25 km every day. Even that small amount stretched the family thin. His mother had to pawn her bangles to pay his fees. She earned just Rs 3 a day back then. Three rupees. That’s the kind of math he was doing with life.

And the commute? That’s where it gets wild

Bus fares were too expensive, so Velumani bought a cheap student pass for the passenger train. The timings didn’t match his classes. So he’d end up waiting for hours on railway platforms every day. Instead of killing time, he studied there. Physics, chemistry, maths. On the platform. With people walking past, trains coming in and out, noise everywhere. He later shared how he spent thousands of hours like this, just sitting there, focused. No café tables. No library corners. Just concrete floors and a lot of determination.

After his BSc, he took a small job at a pharma company in Coimbatore. The pay was Rs 150 a month. He sent most of it home and lived on the rest. When that company shut down, he joined BARC as a lab assistant. Over the next 14 years, he studied more, worked harder, and slowly moved up to become a scientist, specialising in thyroid biochemistry. Quiet progress. No noise. Just work.

Then came the big leap

In 1995, he quit his secure job and used his Rs 1 lakh provident fund savings to start a tiny thyroid testing lab in Mumbai. It wasn’t glamorous. It wasn’t backed by investors. It was just him, a small setup, and a clear idea — make tests affordable so more people could actually get checked. That simple thought changed everything.

Slowly, Thyrocare grew. More tests. More cities. A franchise model that made diagnostics cheaper and faster. He kept reinvesting whatever the business made and lived simply for years. No flashy lifestyle. Just building, step by step. Today, Thyrocare runs thousands of outlets across India and abroad and became a massive name in healthcare.

He’s often said his mother shaped his grit, and his late wife, Sumathi, was the backbone of his business journey. She passed away before Thyrocare went public, which hit him hard. In 2021, he sold a majority stake in the company to PharmEasy in a deal worth thousands of crores. The boy who studied on railway platforms ended up building a multi-crore empire.

It’s wild to think about. But that’s the point.

His story isn’t about overnight success. It’s about sticking around when life is boring, hard, and unfair. And choosing to keep going anyway.
