Arif Nathoo’s long education in slowing down

Arif Nathoo and Web Sun started Komodo Health in a basement at the end of 2014. There is something reassuringly unglamorous about that address. Before the leadership announcements, the investors, and the language of artificial intelligence, there were two people trying to turn a frustration into a business. Nathoo had spent years advising large organizations. Now he would have to make something they could actually use, and persuade them to buy it.

He had an education that offered plenty of respectable ways to avoid a basement. Harvard, then McKinsey, could have supplied a perfectly serviceable career story. Instead, he became a founder. The choice took him into a different kind of apprenticeship, where identifying a problem is only the entrance examination. The rest involves customers, colleagues, money, and the discovery that your own habits may need as much attention as the product.

By 2023, he was prepared to describe one of those habits quite plainly: “I had way too much impatience.” That is an interesting admission from someone whose business is concerned with making work faster. It gives his career a second plot. Alongside the effort to remove delays from software runs the slower business of becoming a person who can lead the people building it.

The basement and the respectable exit

Before the company, there was a long stretch of formal education. Nathoo studied neurobiology at Harvard College and molecular and cellular biology at master’s level, then completed degrees at Harvard Medical School and the Kennedy School. Those qualifications gave him several ways to approach a complicated institution: through science, through policy, and eventually through business. His career would combine them without following the most obvious route through any one of them.

He chose consulting after university training, taking a position at McKinsey. Consulting placed him inside large enterprises, where he could examine how they operated and how they made decisions. It also exposed him to a recurring difficulty: organizations could possess a great deal of information and still struggle to put it to work. The distance between having information and using it became a commercial problem he wanted to solve.

There is a meaningful change in responsibility between explaining a problem to a client and building a company around it. An adviser can deliver a recommendation. A founder must make the recommendation survive contact with a procurement process, a software rollout, and a customer who needs help on Tuesday afternoon. Nathoo’s move with Sun in 2014 put him on that less comfortable side of the table.

The spreadsheet that kept coming back

The work pattern Nathoo wanted to change was familiar: acquire information, have an analyst examine it, and send a spreadsheet or presentation to someone making a decision. Then repeat. Each deliverable might answer the immediate question. The organization remained dependent on assembling the process again when the next question arrived. For a consultant turned software founder, that repetition was an invitation.

The early application was called Aperture. The product gave the company a concrete way to put its underlying work in a customer’s hands. Selling an application also forced a different standard of usefulness. A presentation can make a compelling argument once. Software has to remain useful when the person who designed it has left the room, when another user arrives, and when the question changes.

That distinction helps explain the platform strategy that followed. In a 2022 discussion, Nathoo described a model in which data, analysis, and applications were connected rather than purchased as separate projects. The business proposition was to take some of the assembly work away from customers. A customer buying software wants the result of technical sophistication; relatively few are shopping for the pleasure of managing all its moving parts.

By May 2022, Komodo said more than 40 customers were building on its platform. That was a different relationship from selling one finished application: other organizations were using the foundation to construct things of their own. It widened the company’s responsibilities. A platform becomes part of somebody else’s work, and its reliability matters beyond the boundaries of the business that owns it.

A larger company brings larger obligations

The financing milestones arrived with their own demands. In March 2021, Komodo announced a $220 million Series E led by Tiger Global, with Casdin Capital participating alongside existing investors including ICONIQ Growth and Andreessen Horowitz. The company said the money would support its platform, applications, and underlying assets. The announcement describes a moment of capacity: more resources to attempt more things.

It also describes a moment of obligation. Investment gives a founder room to hire and build, while increasing the number of people who depend on the decisions that follow. A growing company accumulates commitments well before those commitments become visible in its product. Every new layer of ambition needs someone to organize it, explain it, and decide what will wait.

Growth did not remove the difficult chapters. In December 2022, Komodo announced a restructuring that affected about 9 percent of its workforce, roughly 78 people. Its founders addressed the changes publicly as economic uncertainty altered the business environment. Those departures belong in the story alongside the financing. The people leaving a company experience its strategy in a much more immediate way than anyone reading a funding announcement.

This is where the tidy version of entrepreneurship becomes inadequate. A chronology can put investment in one box and restructuring in the next. Leadership has to carry the consequences of both. Nathoo’s later reflections on patience sit against that larger record of decisions. They concern an actual organization, with people whose working lives are affected by how its founders respond to pressure.

A Roman emperor on the reading list

Nathoo’s reading offers another way into his public persona. He names Meditations by Marcus Aurelius as a favorite book and has discussed Stoicism in an interview about building his company. A Roman emperor is unusual company for an enterprise software executive, although both jobs presumably involve receiving unwelcome updates. The detail suggests an interest in questions that a product roadmap cannot settle.

Reading also provides one of his better small jokes. Asked in January 2022 what was on his desk, he described “A stack of books that I'm trying to finish up, but never will.” A reading list is easy to make. Finding the hours is another matter. The answer allows the ambitious executive to appear as something more recognizable: a person who keeps acquiring intentions faster than he can complete them.

In the same exchange, he said that without the CEO job he would be traveling with his wife and children. It is a modest glimpse beyond the business, and a reminder that a career occupies time that could have been spent elsewhere. A company’s progress can be measured through announcements. The cost of attention is quieter and does not come with a quarterly chart.

His reflections on impatience make that question of attention practical. A team needs time to understand a decision, challenge it, and turn it into work. Pushing harder cannot perform all three tasks on its behalf. The interesting thing about a founder admitting this is that it makes learning visible. The person who saw the original opportunity still has to develop the judgment to help other people pursue it.

“I'm still inning one.”

Arif Nathoo, 2023

Two founders, two CEO seats

The partnership with Sun remains central to the current chapter. In June 2026, Komodo announced that Sun would become co-CEO alongside Nathoo, while Miles Ennis became president. The company’s leadership page places data science, engineering, and product development under Nathoo’s responsibilities. Sun’s remit includes operations, business development, sales and marketing, and people. The founders’ relationship now has an explicitly shared executive title.

Another appointment earlier in 2026 points to the practical work ahead. Amit Sangani joined as chief technology officer after eleven years at Meta. Nathoo emphasized his experience taking complex technology into production. That emphasis fits an organization trying to turn its AI platform, Marmot, into something enterprises can use repeatedly. The important test arrives after a demonstration, when the software must fit into an ordinary working day.

A 2025 conversation with Jorge Conde and Jay Rughani had already returned to Komodo’s full-stack approach. The continuity is striking: beneath the changing vocabulary of technology, Nathoo keeps coming back to how the pieces work together. The career that began with examining institutions now asks him to build one that can deliver on its own ideas. Shared leadership and experienced executives are part of that construction.

Twelve years after the basement, Nathoo’s story remains open at a useful point. There is an established business, a continuing partnership, and another round of technical and organizational work to do. His younger self could recognize the appetite to get on with it. The older one has offered a reason to be more deliberate. Somewhere on the desk, one hopes, there is room to finish a book.
