Siva Nadarajah survived two days that could have ended his life. Yet the man who would later challenge Microsoft and walk away from a secure career also turned down a possible early role at Google because he needed health insurance. His story is not about becoming fearless. It is about learning which risks deserve a yes, which demand a no, and what each decision protects.
He was a schoolboy in Jaffna when the city burned around him. The hostel emptied. Five boys remained, along with a cook who refused to abandon them. A friend’s father eventually came through the violence, gathered the boys, and found a way to move them nearly 300 kilometers back toward the hill country. Years later, after another bombing, Siva was pulled from a bus with other Tamil passengers. He spoke Sinhala well enough to be released. The others, he says, disappeared.
Two days. Two exits from death. Everything that follows in his story seems to carry their imprint.
I expected to talk about a repeat entrepreneur and a digital health company. I came away thinking about how a person behaves when fear has already shown him its worst face. Siva’s boldness appears in small, almost unreasonable acts -walking into an office that ignored his application, challenging Microsoft in his second week in America, and leaving a comfortable post-exit life because a child’s first steps made the work impossible to treat as a side investment.
But the deeper lesson is not “trauma makes great founders.” That would be a cheap reading of a terrible history. Siva repeatedly returns to the people who did not get to tell their stories. His fearlessness is inseparable from survivor’s gratitude. He does not present the war as an advantage. He presents each ordinary day as borrowed time.

The Two Days That Changed The Size Of Fear
The most striking line arrived early. When tomorrow itself had once been uncertain, what could ordinary risk possibly mean?
“If your life wasn’t guaranteed the next day, what is risk for you?”
Siva Nadarajah
That question explains much of his life, but not all of it. Fearlessness without ability is recklessness. Siva paired it with an appetite to learn. The other inheritance was proportion. He remembered bomb blasts followed by people watching a Rajinikanth movie the next day. Life continued. Business setbacks rarely deserved the emotional scale we give them.
When Sri Lanka’s universities closed amid unrest, he went to Colombo looking for work. An international school did not respond to his application, so he walked into the director’s office and demanded the courtesy of an answer. There was no school job. There was, however, a video store and a bargain -work there, and the director would teach him computers.
Siva began by cleaning cassettes, learned the customers, and earned responsibility for the store. When a better-funded competitor gained faster access to new films, he changed the model. Customers could return a movie early for a discount, and a bicyclist would move the cassette to the next home. Long before “sharing economy” entered the business vocabulary, a teenager in Colombo was increasing the use of an idle asset.
This matters because the pattern repeats. Siva does not wait for a system to validate him. He studies the system, finds the unused opening, and moves through it.

The Immigrant Who Kept Walking In
His first month in America compresses an entire immigrant career into a few weeks. He arrived in Chicago in December without the right coat. His hands cracked in the cold. He did not yet have his own apartment. Then he found a security flaw in Hotmail.
Microsoft rejected his warning. Siva did not conclude that the institution must know better. He took the issue to a journalist, who tested it and published the story. He had been in the country for two weeks.
“I come in in the cold, and within two weeks I find a glitch in Hotmail and fight with Microsoft.”
Siva Nadarajah
America did not create that instinct. Sri Lanka did. What America supplied was a larger stage and, crucially, an ecosystem where a journalist could challenge a giant company and give an unknown engineer a hearing.
My pushback is that we should not turn this into a fairy tale about confidence alone. Siva could walk into rooms because he had done the work. He understood internet security when the field itself was young. He had written publicly, built technical credibility, and learned enough to know when a powerful institution was wrong. The lesson is not “be loud.” It is “be prepared enough that your refusal to be ignored has substance behind it.”
There is something deeply first-generation in the combination -deference learned in one culture, voice learned in another. Siva came from what he calls a “yes, sir” environment. America rewarded the part of him willing to question Microsoft, then forced him to learn a harder skill: saying no before enthusiasm scattered him in every direction.

The Discipline of NO
One of Siva’s earliest noes has become family folklore. A recruiter approached him in 1998 about a tiny search company looking for Linux and search-engine expertise. The company did not offer health insurance. Siva declined before interviewing. He later learned the company was Google, and the recruiter had described the role as roughly its tenth employee.
It is tempting to call that the most expensive no of his life. I do not.
He was a new immigrant making a decision with the information and vulnerability he had then. Health insurance was not a trivial perk. It was safety in a country whose systems he was still learning. Judging the choice only through Google’s later success is outcome bias. The more useful lesson is that every no protects something, and sometimes what it protects matters more than the upside we can see only in retrospect.
Decades later, ‘no’ has become central to how he runs JOGO. The company’s technology has potential applications across multiple conditions, and Siva described interest from dozens of countries. Early on, he said yes too quickly. Launch attempts in Malaysia and Canada exposed the cost of entering a market before understanding its regulatory, payment, and care-delivery realities.
His metaphor for focus came straight from the world that raised him.
“It’s like you are on a nice town bus going from your village to town. There’s a tea shop, get the tea, but you get on the bus. Your destination is there.”
Siva Nadarajah
That may be my favorite operating lesson from the episode. Curiosity is allowed. Detours are allowed. You can stop for tea. Just do not mistake the tea shop for the destination.

The Company Is A Continuation, Not The Hero
Siva describes JOGO as an “external brain.” In practical terms, the company combines wearable sensors, software, and clinician-guided therapy to help patients retrain impaired communication between brain and muscle. He entered first as an investor, not an operator.
Then a family connection asked whether the technology might help a 13-year-old girl with cerebral palsy. Siva told me she later walked to the bathroom with support for the first time. That moment changed his relationship with the company. An investment became a calling.
“JOGO is your external brain.”
Siva Nadarajah
The patient stories are powerful, including a man with severe pelvic pain who told Siva the treatment had pulled him back from suicide. They explain the mission, but cannot carry the evidentiary burden of healthcare. A moving story is a reason to investigate, not a substitute for clinical rigor. Siva’s hardest operating lessons were about reimbursement, licensed care, market-by-market delivery, and the discipline required to make technology reach patients.
The company reveals Siva’s operating system. The younger Siva walked in. The older Siva still walks in, then asks who pays, who delivers care, what regulation applies, and what must be declined so the core survives.

The Most Important Thing He Built Is Not A Company
The part that most surprised me had nothing to do with JOGO.
After selling his earlier company, Siva put money into a foundation in Sri Lanka. Its team goes home to home in the plantation communities he came from, looking for children at risk of leaving school to work as domestic servants. The foundation supports them through the final years of high school. It also pays families, because keeping a child in school is not simply an educational decision when the household depends on the income that child could bring home.
Siva says the effort has now helped roughly 2,000 children. He does not know them personally. He designed it that way. There are staff, selection processes, quarterly metrics, and a clear boundary around the mission. Even here, compassion is operationalized through focus.
“The more money I make, the more children will benefit. That’s all.”
Siva Nadarajah
I was blown away by the scale, but more by the absence of performance around it. There are no letters arriving to make him feel heroic. He built a system intended to work without making him the center of every story.
This is also where his philosophy of no becomes morally complicated and therefore more useful. Once people know you help, every worthy need comes toward you. A medical emergency. Another village. Another cause. Siva says no so the children already inside the commitment are not diluted by his desire to answer everything. In business, focus protects the company. In philanthropy, focus protects the promise.

The Language In Which We Grieve
Culture in Siva’s life is not decoration. It is where memory is stored.
He grew up among Tamil and Sinhala friends, and he resists reducing Sri Lanka to simple ethnic categories. In America, he feels an immediate bond with Sri Lankans across communities. But Tamil carries something different. It is the language in which war can be remembered without explanation.
“We think and cry in our own language.”
Siva Nadarajah
That sentence brought me back to the Sri Lankan Tamil couple who drove to Dover during my English Channel training with hot idlis, simply because I was a Tamil child shivering far from home. Language can create kinship before biography catches up. Siva gave the other side of that truth: happiness travels easily across cultures, but grief often needs the exact language in which it was first felt.
His present life resists clean separation -morning Hindu chanting he jokes he cannot turn off, Tamil film music on a walk, Bloomberg for the markets, a day inside an American health company, Sri Lankan food, and Tamil movie reviews at night. He also credits America with expanding his acceptance of people unlike him, including views that create friction with relatives back home.
Living between two worlds has not made him half of each. It has made him more opinionated about both. He keeps the food, music, language, and grief. He adopts the American permission to question authority and widen the circle of belonging. The crossing is not a clean exchange. It is a continuing argument inside one person, and in Siva’s case, that argument has produced a life he has very deliberately carved for himself.
Five takeaways worth keeping
Clear lessons readers can carry into their own works
01. Do not romanticize fearlessness.
Siva’s courage came from surviving what no child should face, and he never separates his survival from the people who did not make it. Take the perspective, not the trauma.
02. Earn the right to walk in.
He challenged an employer, Microsoft, investors, and healthcare orthodoxy, but his boldness was backed by study and competence. Voice carries farther when there is work underneath it.
03. Judge a decision by what was knowable then.
Declining a tiny company that became Google looks absurd only with hindsight. Protecting health insurance as a new immigrant was rational. Outcome and decision quality are not the same thing.
04. Stop for tea, then get back on the bus.
JOGO’s failed expansions taught him that opportunity is not strategy. The ability to say no is what converts ambition into a destination.
05. Build systems that do not need your heroism.
The foundation’s power is not only that it has supported roughly 2,000 children. It is that Siva created a team, process, and measurable commitment that can keep serving them without turning their lives into his personal applause line.
