Some startups talk about impact. Water Harvesting Inc. just wrung water from the air, in the middle of the desert, and made it profitable.
Founded in 2018 and rooted in MOF science cooked up over two decades at UC Berkeley, WaHa is what happens when deep science meets real-world necessity. Atmospheric water generation (AWG) isn’t some sci-fi fever dream, it’s now patented, deployed, and producing at 98.3% of target water volumes in places like West Texas, Riyadh, and Stockholm. And yeah, it’s doing it at 15% humidity. That’s not luck, that’s molecular engineering meets ruthless execution.
Co-founders Frank Ramirez (CEO) and Chris Kay (President/COO) didn’t walk into climate tech for the headlines. They’ve done this before, Ice Energy, Endūr, they’re serial operators who understand the grind. Add in Eugene Kapustin as CTO, the Berkeley-trained chemist behind 15 patents in MOFs, and David Kuo (EVP of Engineering), the former Seagate director with 110 patents under his belt. That’s not a team. That’s a precision-built SWAT unit for water tech.
Now, WaHa just closed an $8 million Series A-1 financing round, no flashy VC logos, just real capital from people who know how to back deep tech: Chairman Mike Phillips and board member Christian Thirion led the round, with support from Berkeley Catalyst Fund, Anthropocene Institute, Vestafund, and Mitsui Mining & Smelting Co., Ltd. Notably, this wasn’t just a fundraise, it was a reset. Debt cleared, cap table cleaned, cash ready to unlock a growing sales pipeline across the UAE and GCC. Translation: WaHa’s not chasing traction. They have it, and they’re scaling.
Let’s talk tech. The patented WaHa Vaporator® system isn’t just squeezing water from the air, it’s slicing HVAC energy costs by up to 50%. It runs off-grid. It modularizes like Lego. It performs with 99.998% mechanical reliability. And when it ran field trials at Khalifa University? Full uptime. Near-perfect reliability. Water-as-a-service is no longer a hypothetical, it’s now a commercial strategy negotiating real deals with water utilities across the Middle East.
This isn’t just a company hitting commercial launch at WETEX 2025 in Dubai, it’s the emergence of a category-defining platform. One that scales from controlled-environment agriculture to semiconductor fabs to lithium battery production. If climate tech is the new infrastructure, WaHa is the faucet getting opened.
To the skeptics still wondering if deep tech and commercialization can share a room: WaHa just answered in fluent desert air.
