Uravu Labs makes water out of air, and yet what the Bangalore startup builds interests me less than what it decided: stop selling water as water. In atmospheric water generation, the cost of water is really the cost of heat, and Uravu’s own numbers make the point, at 2 cents a liter on grid electricity, 1 cent where the heat comes free. So instead of chasing the humanitarian market that swallowed $270 million at SOURCE Global alone, Uravu pays its bills selling premium water to hotels and breweries, roughly $1 million a year from one factory that sells over 80% of what it makes, and hunts the places where waste heat is free. The flagship target is data centers, a $569 million water-CAPEX market that will spill out close to a thousand terawatt-hours of heat by 2030. The question I want to walk through is whether hunting applications, rather than praying for cheap water, is how water-from-air finally becomes a business.

What is Uravu Labs known for?

Uravu Labs was founded in Bangalore in 2019 by engineers whose campus had run dry in 2016; co-founder and CEO Swapnil Shrivastav was one of five finalists in the $1.75 million Water Abundance XPRIZE, the only Indian team of the five, picked from 98 entrants (WaterWorld covered the 2018 finalist round). That prize asked for 2,000 liters a day at 2 cents a liter on renewable energy, a bar Uravu would chase for the next seven years.

The XPRIZE glory did what glory does: the first customers never came. They tried everything the “water for all” playbook prescribes, CSR budgets, NGOs, community devices, and nobody would carry a new technology’s risk. So they shifted gears, and the reset became the company, in Swapnil’s words: “today we sell the water… we don’t sell the technology”, to customers who already pay bottled-water prices.

An atmospheric water generator, to define it before judging it, pulls the moisture sitting in ambient air and turns it into drinking water, by cooling air below its dew point like a dehumidifier or by soaking moisture into a sorbent and releasing it with heat.

How much does atmospheric water generation cost?

Swapnil Shrivastav’s levelized cost curve for Uravu Labs, stated on my microphone in August 2025, runs from 10 to 12 cents a liter five years ago to 5 cents two years ago and 2 cents today, computed with grid electricity at 12 cents per kilowatt-hour, and 1 cent where the heat comes free. Levelized simply means the machine’s whole life is in the number, capital included.

Christopher Gasson, the publisher of Global Water Intelligence, famously called atmospheric water generation an “egregious waste of money”, and the numbers backed him, with desalination at 30 to 40% of its thermodynamic optimum and AWG near 5%. Swapnil doesn’t argue with the ceiling (water from air, he says, will not beat desalination for 10 or 15 years), so the question worth asking becomes “cheap enough for whom”.

And the curve explains the strategy: the drop from 12 cents to 2 came from engineering, while the drop from 2 to 1 comes from somebody else’s heat. Once you see that, you stop asking where water is expensive and start asking where heat is free.

The strategy: stop looking at water as just water

Uravu Labs runs two tracks at once, and the split is the strategy. Track one keeps the lights on: hospitality and beverage customers in Bangalore, an Italian-style microbrewery among the first believers, roughly $1 million in annual recurring revenue from a segment Swapnil honestly caps at about $10 million, served by a factory that pays itself back in under 24 months. He calls it the Tesla strategy (premium niches first while the technology matures), and over 80% of every liter made in two years was actually sold.

Track two is the bet, and he framed it with the line that gave this article its spine:

In practice that means hunting two or three markets whose own economics carry the water along, data centers and climate-controlled agriculture are the two he names, with a 2-meter cube that fits a standard 20-foot shipping container as the deployable unit. I covered where that discipline comes from in my newsletter on seed-strapping: too much cash, in his words, makes you solve problems by throwing money.

Do data centers really need water from air?

Data centers are the flagship application Uravu Labs is hunting, and the sizing goes like this: in 2025, Global Water Intelligence estimated the water CAPEX of data centers at $569 million for the year, cooling taking about 80% of it, while the International Energy Agency’s 2025 Energy and AI report projects data centers consuming around 945 terawatt-hours of electricity by 2030. Nearly all of that leaves the building as heat, and against that torrent, the projection I walked through in the episode editorial puts reused data-center heat at about 3.5 terawatt-hours a year by 2030. In the editorial I called it what it looks like: “not a gap, it’s a canyon”.

The 1 MW arithmetic

The expensive step of desiccant-based water-from-air is the heat that drives the water back out of the salts, and a data center manufactures exactly that all day long. By Uravu’s projections, feed the system a 45°C stream and you drop it to 30°C for each megawatt of waste heat used, collecting about 20 cubic meters of water a day. I fact-checked that claim in the episode: it works out to 0.83 liters per kilowatt-hour of heat, within the envelope of peer-reviewed efficiency figures, on the efficient end. And the output is distilled, which happens to be exactly what a cooling loop wants to drink (scaling and fouling, the two words every cooling engineer mutters in their sleep). I dissected the full thesis in my newsletter edition “VCs vs. Physics: Who Wins?”, and if you enjoy this kind of rabbit hole, that’s the one to subscribe to.

Where could the strategy break?

Swapnil Shrivastav supplies his own counterweight, and he does it better than the skeptics: asked when a data center actually runs on this, he answered that any integration at scale is realistically two years away, because data centers are critical infrastructure and nobody lets a Bangalore startup plug an experiment into a live cooling loop. In the companion newsletter I added two structural caveats of my own: operators “are here to play with Data, AI and cute pictures of babies stored on drives”, not to optimize exotic water tech, and “if heat networks take off, selling heat will always be a better monetary deal than selling water”.

The $497 million counterfactual

And picking the wrong application is not a hypothetical risk. I mapped the whole category in my Leviathan database: 32 companies carry the atmospheric-water-generation tag, with disclosed funding of $497 million. So let’s do the maths together: SOURCE Global, which sold hydropanels as a “water for all” play, raised $270 million by ESG Today’s 2022 tally ($223.8 million of it in rounds my database can see), and was declared dead in early 2025, four months before Uravu closed its fifth round. That one bet absorbed 45% of every disclosed AWG dollar, and with the other casualties added, 45.4% of the category’s lifetime capital now sits in dead or distressed companies. Colin Goddard, then SOURCE’s VP North America, had told me on this same microphone the goal was “the cheapest water on Earth”, and thermodynamics had other plans.

Is the smart money buying the strategy?

The data-center thesis reached Uravu Labs through its own cap table: about 18 months before our conversation, investor Peter Yolles of Echo River Capital kept sending Swapnil stories about data centers drinking whole towns’ worth of water; the founder went hunting, and the investor later cut a follow-on cheque. By late 2025 I counted nine AWG companies raising within the year, Echo River’s follow-on among them, in my “Four Questions About Source” edition.

Now the wallet-level evidence, from my Leviathan database again: Uravu’s syndicate has widened every full round, 5 investors in the 2021 pre-seed, 8 in 2022, 9 in 2023, 10 in the July 2025 round that funds the pilots, with $3.5 million disclosed (Inc42 pegged the total near $4 million in April 2023, so read that figure as a floor). And one stat I couldn’t resist computing: not one of SOURCE Global’s 17 backers, Gates, Bezos, Jack Ma, Masayoshi Son, Branson, BlackRock, appears on Uravu’s cap table. For the wider context, my State of Water Tech Funding 2025 has the full picture.

FAQ: the questions people actually ask

Do data centers use water?

Yes, mostly for cooling: Global Water Intelligence sized data-center water CAPEX at $569 million in 2025, cooling taking about 80%. Uravu’s angle is to flip the same problem around: use the heat side to produce water instead of only consuming it.

What is an atmospheric water generator?

A machine that harvests the moisture in air and turns it into liquid water, by chilling air below its dew point (the dehumidifier route) or by absorbing moisture into a desiccant and driving it out with heat. Uravu abandoned the first route after 1.5 years: below 50 to 60% relative humidity, it stops cooperating.

How do you make water from air without electricity?

Strictly speaking you don’t, but you can make it without dedicated energy. By Uravu’s fact-checked projection, a 45°C waste-heat stream dropped to 30°C drives the desiccant cycle at about 0.83 liters per kilowatt-hour of heat, landing near 1 cent a liter versus 2 cents on grid power.

Do atmospheric water generators really work?

They work; the honest question is where they make sense. The category runs near 5% of its thermodynamic optimum against desalination’s 30 to 40%, so pure drinking-water plays lose to wells, tankers and bottles almost everywhere. They earn their keep where quality or an allied application, cooling above all, carries the economics.

What is the revenue of Uravu Labs?

About $1 million in annual recurring revenue from the Bangalore consumer and hospitality business, a segment Swapnil himself caps at around $10 million, which is precisely why the company is hunting bigger applications.

Is Uravu Labs water safe to drink?

What leaves the machine is distilled water at near-laboratory grade (pH around 7, near-zero dissolved solids, in Swapnil’s words almost pharma-grade ASTM Type 3), which the company then supplies to hospitality and beverage customers.

What is the future of Uravu Labs?

Ten to fifteen replications of the Bangalore factory, a project deployed in Abu Dhabi, and data-center pilots targeted within 6 to 12 months, with integration at scale a couple of years out by the founder’s own estimate.

The two-year test

So, does the strategy hold? My honest read: the physics argument for waste-heat AWG is sound, the fact-check landed on the efficient-but-plausible end, and the funding pattern (small cheques, a widening syndicate, an investor who seeded the thesis) looks like conviction rather than fashion. But the strategy has written its own exam: within roughly two years, either a data center lets Uravu bolt onto its cooling loop, or the flagship application stays a well-argued pitch while hotels and breweries keep the company alive.

Swapnil, who at 29 calls himself probably the oldest person in his company, is spending the new round to force the answer, and he closed our conversation with an open call to data-center and climate-controlled-agriculture operators who want to co-create a pilot. And if you want to judge the bet yourself, listen to the full episode below, because the best due diligence in water tech is still hearing a founder argue against his own pitch.
