Chapter Six: San Juan — Where the Ocean Is the Best Reset Button

San Juan is home now.

After Russia, Cambodia, and years on both American coasts — after Moscow lecture halls and Stanford classrooms, after Uber's marketplace and Tesla's factory floor and Waymo's driverless streets — Vasily Starostenko runs his companies from Puerto Rico. And he will tell you, without hesitation, that the island changed how he builds.

Aquí se trabaja duro y se vive bien. You work hard, and you live well. The Caribbean has a way of stripping away everything performative about startup life and leaving the part that matters: does the business work, and does the life work?

Both, he will tell you, are working.

The Owner-Operator

From San Juan, Vasily operates as a true owner-operator — a phrase that means something specific and increasingly rare. There is no board. No investors to report to. No layers between the decision and the result. When something needs to happen, he makes it happen. When something breaks, he fixes it. When a customer calls, he answers.

There are two businesses, and they could not be more different — which is exactly the point.

Sleep Shop is physical, local, hands-on. New-in-box metal bed frames — Twin, Queen 6-inch, King 6-inch, and King 10-inch — with pickup in San Juan. Real inventory. Real customers. Real trucks, real frames, real conversations in Spanish about which size fits which room. It is the kind of business that Silicon Valley forgot how to respect: unglamorous, essential, profitable because it solves an actual problem for actual neighbors.

Callpages is digital and global. The product he built so that every business can have a great call page — a clean, fast page whose entire job is to turn a visitor into a phone call. It carries the fingerprints of everything he learned at scale: the obsession with customer experience from Revolut, the operational rigor from Waymo's fleet work, the growth instincts from Tesla and Uber. Enterprise-grade thinking, small-business simplicity.

One business is physical. The other is digital. Both run from the same desk, on island time, with mainland standards. And both benefit from the same discipline: understand what the customer needs, remove friction, deliver something better than what was there before.

Living in a Spanish-speaking market keeps him honest as a product person in a way that California never did. When your customers, suppliers, and neighbors operate in two languages, you learn fast which of your assumptions were just Silicon Valley habits. Clarity beats cleverness. A phone call beats a funnel. Showing up — literally, in person, on time — beats every growth hack ever invented.

The island rewards operators who show up. That suits him fine. Showing up is what he has done every morning since he was a kid in a cold pool in Russia.

Documenting the Island

He documents San Juan the way a founder documents everything: in the open, personally, without pretense.

There is the wristband — a simple keepsake reading "of SAN JUAN," photographed and kept as a small trophy of belonging. It is the kind of object that means nothing to anyone else and everything to the person who kept it. A marker: I am from here now. This is mine.

There is the agenda of ICON Summit 2024, held in San Juan — sessions running from the space industry to housing crises to AI to digital payments to economic development. He photographed the agenda the way an operator photographs everything: as data. What is this island thinking about? Where is it going? What problems is it trying to solve? The builder's mind never stops mapping the territory.

There is Digitize 3.0 — the seminar certificate from June 2024, issued by Puerto Rico's Department of Economic Development and Commerce, covering eCommerce strategies for small and medium businesses, signed by Secretary Manuel Cidre Miranda. Even here, even now, the student shows up. The MIPT habit endures: learn the system before you try to master it.

And then there is the jazz night.

In December, at the Anfiteatro Rafael Hernández in Santurce, Vasily filmed a night jazz concert — and set it, with characteristic cultural playfulness, to Баста's "Чёрный человек" (Black Man), a Russian rap track. A Puerto Rican jazz night scored to Russian hip-hop, filmed by a man who now lives in Spanish. Two cultures, one phone camera, zero pretense.

This is what integration looks like — not the erasure of where you came from, but the joyful layering of everywhere you have been. The Russian soul does not disappear in Puerto Rico. It finds a new rhythm section.

The Ocean: Teacher and Reset

For a former competitive swimmer — a tenfold Champion of the Moscow Region — it is hard to imagine a more fitting place than San Juan. The island gave him what the Moscow pools never could: warm open water, year-round, a few minutes from home.

The Caribbean did not make him a swimmer. It gave the swimmer in him a new ocean.

Life in San Juan runs at a different tempo than the startup cities he worked in, and that is the point. The ocean and the outdoors are his reset — the place where a founder's overworked mind goes quiet and the real thinking happens. There is a particular clarity that comes from time in the water, the kind you cannot schedule in a calendar. Vasily has trusted it since he was a kid chasing championship times. He trusts it now between product launches.

He photographs the coast the way he swims it: personally. A first-person shot — his own feet in the sand under an overcast sky, blue swim trunks, the honest unglamorous reality of a beach day. A panoramic sweep of white-capped waves and palms under a blue sky, the postcard view that never gets old. And, with a founder's respect for reality, the orange "PELIGRO PROHIBIDO EL PASO" signs where the surf turns dangerous — danger, no entry — because the ocean, like any good teacher, does not grade on a curve.

The ocean is his reset and his teacher: beautiful, honest, and not to be argued with.

There is something about the place that matches the philosophy he teaches. The ocean does not care about your roadmap. It is the ultimate honest scoreboard, just like the pool clock was. You either respect the conditions or you do not. That kind of honesty — no vanity metrics, no spinning the result — is a fine way to run a life. It happens to be how he runs companies too.

Una isla pequeña, una ambición grande. Small island, big ambition.

The Daily Practice

La isla teaches balance the way Moscow taught rigor: not as a theory, but as a daily practice.

The mornings start early — the swimmer's discipline survived every crossing. The work gets his full intensity: the companies, the products, the customers. But the ocean is never far, and the culture insists on something that the previous chapters sometimes forgot: that a life is meant to be lived, not just optimized.

This is not laziness. It is not a lack of ambition. It is a deeper understanding of what ambition is for. The Moscow years taught him to work. The California years taught him to scale. Puerto Rico is teaching him something equally valuable: that the point of building is not just the building, but the life the building makes possible.

He still measures. He still iterates. He still wakes up with the discipline of a champion. But now the metrics include things that do not fit on a dashboard: the quality of a morning swim, the satisfaction of a customer served in person, the joy of a jazz night under Caribbean stars.

Es un buen lugar para construir — it is a good place to build. And he plans to keep building here for a long time.

Teaching from the Island

The island has not slowed his teaching — if anything, it has deepened it.

Vasily has been a Udemy instructor for years, with his flagship course "Product Management for Maximum Impact" reaching thousands of students — some bios say tens of thousands. It is the same material he speaks about on stages: automation, product experimentation, understanding customer needs, managing for maximum impact. But teaching from San Juan adds something the California years could not: the perspective of someone who is simultaneously operating at global scale (through Callpages and advisory work) and at neighborhood scale (through Sleep Shop).

Students get both. The frameworks refined at Uber, Tesla, Waymo, and Revolut — and the ground truth of running a local business where the customer is standing in front of you. Theory and practice, in the same voice, from the same desk.

There is a particular credibility that comes from teaching while doing. The instructor who shipped this morning hits different from the instructor who shipped five years ago. And the operator who can explain why — who can connect the bed frame delivery to the marketplace incentive to the physics first principle — is teaching something no textbook contains: the integrated view, the whole system, the way it all connects.

The Open Door

For visitors and locals alike, the door is open.

If you are passing through San Juan and want to talk products, startups, swimming, or island life — reach out. The fastest way is a call. And if the timing works, the conversation might just happen with the sound of the ocean in the background.

This is not a metaphor. It is an invitation. The owner-operator answers his own phone.

What the Six Chapters Add Up To

Look back at the arc:

Chapter One gave us the boy in Russia — the physics homework, the cold pool, the belief that every problem has a structure.

Chapter Two gave us the forge — MIPT and NES, first principles and incentives, ten swimming championships alongside an honors physics degree.

Chapter Three gave us the crossing — America, English, Stanford. The outsider becoming the insider without losing what made him an outsider.

Chapter Four gave us the arena — Uber, Tesla, Waymo, Revolut. The operator's education, the four patents, the teams scaled to a hundred.

Chapter Five gave us the third crossing — Puerto Rico, Spanish, the citizenship certificate. The island saying yes back.

Chapter Six gives us the home — San Juan, the ocean, the businesses, the daily practice of building a life, not just a career.

The pattern held every time: choose the hard crossing, accept being a beginner, apply the swimmer's discipline, integrate rather than replace. Russia to America to Puerto Rico. Physics to economics to business to ownership. Russian to English to Spanish.

And the story is not over. The businesses are growing. The Spanish is deepening. The ocean is still there every morning, honest as a stopwatch. New chapters are being written — in three languages, on a Caribbean island, by a man who treated every problem like physics homework and discovered that the hardest, most beautiful problem was how to build a life.

The forge was Moscow. The arena was California. The home is San Juan.

And the swimmer is still in the water.

What comes next is still being written — new products, new students, new mornings in the ocean. The six chapters behind are not a conclusion but a foundation. Every crossing taught the same lesson in a new language: the work is the reward, the discipline is the freedom, and the best time to start building is always now. The island knows this. The ocean has always known it. And the boy who treated every problem like physics homework grew up to discover that the most important problems — a life, a home, a business built with your own hands — are the ones most worth solving.
