The woman who left Kolkata with $200 and came back
with a boat that flies.
She convinced Google's co-founder to back an electric boat nobody had built yet - and then she built it.
Right now, somewhere in San Francisco Bay, a 30-foot electric boat is hovering four feet above the water, moving at 35 knots, generating almost no wake, no noise, no emissions. Sampriti Bhattacharyya built that boat.
She did not do it the obvious way. She grew up in Kolkata in a household with no engineers. She applied to 540 internships from a Compaq computer and got four replies. One of those replies was Fermilab. She arrived in the United States at age 20 with $200 in her pocket. That is not backstory padding - it is the actual operating system she runs on.
At Ohio State she took a master's in aerospace engineering. Then NASA. Then TIFR. Then MIT, where she earned a PhD in mechanical engineering focused on underwater robotics. In 2014, when Malaysia Airlines Flight 370 vanished into the Indian Ocean, she was deep inside MIT's robotics labs working on underwater drones. She looked at the scale of the search operation - the world's best navies, flailing - and recognized something: there was almost no technology adequate to the ocean. That gap did not read like a tragedy to her. It read like a market.
Her first company, Hydroswarm, built autonomous underwater drones. It failed - IP complications, visa complications, the particular grinding friction of early-stage hardware startups. She absorbed the loss, kept the lessons, and pivoted onto a different body of water. In 2020, she co-founded Navier with MIT engineer Reo Baird.
The premise was simple enough to sound crazy: the world's coastal cities are strangling on road traffic while their harbors sit largely idle. What if you could make a boat efficient enough, fast enough, and smart enough to become actual transportation? Not a weekend toy. Daily infrastructure.
In a year, a person spends over 100 hours in traffic. Waterways are this infrastructure, already built out, that's underutilized.
- Sampriti BhattacharyyaNavier's N30 is the proof-of-concept scaled into a real product. It is 30 feet long, seats eight passengers, and rides on three carbon hydrofoils that lift the hull completely clear of the water at speed. The drag reduction is what makes the efficiency math work: no hull-in-water means no wave-making resistance means a range of 75 nautical miles at 22 knots. The comparison to gas boats is not a rounding-error advantage. It is a factor of ten.
She also built the software. Navier's proprietary operating system reads real-time wave conditions through onboard sensors and continuously adjusts the foil angles to keep the ride glass-smooth. It autodocks. It has advanced autopilot. These are not luxury features bolted on - they are load-bearing parts of the argument that this can become mass transit.
There is a version of this story where you call her an unlikely founder. She grew up without engineers in the family, studied at a small college where she was not considered especially gifted, in a city that did not particularly encourage women toward aerospace careers. She never ran that version.
She sent 540 emails. She tracked down Fermilab on her own, applied cold, made it work. The physics-first philosophy she talks about now - "if it's not against the laws of physics, it's possible" - is not a polished sound bite. It is the actual heuristic she used at 20 to decide whether an internship in the United States was achievable.
That same reasoning is what she applies to boats. Traditional hulls push through water - that's against no laws of physics, just enormously inefficient. Hydrofoils lift the hull free - also not against any laws of physics. So: build the hydrofoil. Make it electric. Make it smart. Solve the range problem. Deliver the first one in 2024.
What she does not do is over-romanticize the path. She had a company fail. She knows what hardware startup death feels like. She chose to go again anyway, this time with better co-founders (Reo Baird, MIT-trained), better investors (including Google co-founder Sergey Brin and Android co-founder Rich Miner), and a product category where she thought the physics were genuinely on her side.
Be stubborn on vision, but flexible on details.
- Jeff Bezos, quoted by Bhattacharyya as guiding philosophyThe N30 is not Navier's pitch deck. It is their delivered product. The first Pioneer Edition reached a customer in California in October 2024. The first commercial delivery followed in May 2025. What makes it noteworthy is not the price tag - though starting at $375,000 for the open configuration, it occupies serious territory. What makes it noteworthy is what it proves is buildable.
Paul Bieker, the lead naval architect with 35 years of experience designing America's Cup campaigns, joined to handle the hull and foil work. CTO Kenny Jensen came from Makani (Google/ARPA-E's wind energy moonshot) where he led flight controls. These are not boating industry veterans - they are people who have built machines that needed to fly.
Because that is what the N30 does. It flies. Four feet above the surface, on three carbon foils, while software reads the water and adjusts the wings forty times per second.

If it's not against the laws of physics, it's possible.
People don't see you as the most likely person who might be building something crazy wild.
Waterways are this infrastructure, already built out, that's underutilized. 46% of the world's population lives in crowded coastal areas.
If every marina can be a transportation hub, more waterfront infrastructure develops. There will be a whole new wave of economic activity.
From the physics of it, it must not be impossible - there must be a path.
Autonomous boats may emerge before autonomous cars.
ZERO-EMISSION HYDROFOIL: SAMPRITI BHATTACHARYYA ON NAVIER'S ELECTRIC BOAT REVOLUTION
The N30 is a 30-foot, $375,000 foiling yacht. The vision is a coastal city where every marina is a transit hub. Those two things are not contradictions - they are a sequence. The luxury boat proves the platform. The platform enables the water taxi. The water taxi enables the barge. The barge decongests the city.
Bhattacharyya believes autonomous boats may beat autonomous cars to commercial deployment. Her argument: the ocean has no pedestrians. No intersections. The sensor data is cleaner. Generative AI can produce synthetic training data for wave conditions. The regulatory pathway is different. The obstacles are real but tractable.
She also has a macro thesis: 46% of the world's population lives in coastal areas that are increasingly gridlocked. The road infrastructure is built. The waterway infrastructure is also built - and almost entirely unused for daily transit. The cost of adding water capacity is a fraction of building new road capacity. The physics are in her favor. The economics are in her favor. The only question is execution.
She has been executing since age 20. The 540-email habit does not appear to have left her.
