The most expensive part of cooling a data center in the desert is not the electricity. It's the capital to build the cooling system in the first place. Strataphy, a startup based in Khobar, Saudi Arabia, is betting that if you can make that upfront cost disappear, you can sell cooling the same way you sell software. They call it Cooling as a Service, and their hardware is a proprietary shallow-geothermal loop they've named PrimeLoop. It's a bet on turning the ground beneath your feet into a giant, passive heat sink, and they've just raised $6 million to prove it works at scale [Wamda, Nov 2025].
A service model for the earth's cool
Strataphy's core proposition is simple. Instead of a factory or data center buying and installing massive chillers, Strataphy designs, installs, and operates a geothermal cooling system for a monthly fee. The customer gets cool air, Strataphy owns the subsurface hardware. The company's PrimeLoop system is a closed-loop network of pipes that circulates a fluid deep enough to reach stable, cool temperatures, then brings that chilled fluid back up to exchange heat with a building's cooling infrastructure [Businesswire, Jan 2025]. The magic, they claim, is in making this work reliably across diverse geological formations, something enabled by their patent-pending completion and design technologies [Businesswire, Jan 2025].
The potential energy savings are the main hook. According to industry analysis, geothermal cooling can reduce the electricity consumption for cooling by up to 50% compared to conventional air conditioning [ThinkGeoEnergy, 2026]. In a region where cooling can account for 70% of a building's energy bill, that's not just a sustainability win. It's a direct line to healthier unit economics for any facility manager staring down a utility bill.
Founders from the subsurface
The team behind Strataphy brings a specific kind of credibility to a problem that is, literally, underground. Co-founders Ammar Alali and Ahmed Alhani have over 15 years of combined experience in subsurface exploration and energy optimization, including prior work at Saudi Aramco [TechAfrica News, Nov 2025]. Alali, the CEO, is also a PhD student in Energy Science Engineering at Stanford and previously co-founded a geothermal energy startup [Stanford Profiles, 2026] [Forbes, Jan 2020]. This isn't a team of software engineers discovering HVAC. Their backgrounds suggest they understand the complexities of drilling, geology, and the industrial sales cycles of the energy sector.

The path to 100 megawatts of cool
Strataphy's ambitions are measured in thermal capacity, not revenue. Their public targets lay out a clear, if aggressive, roadmap. In the near term, the company is targeting the installation of over 15 megawatts-thermal (MW-th) of cooling capacity within the next three years [strataphy.com/news, 2026]. The medium-term goal is 50+ MW-th within five years, with a long-term vision of reaching 100 MW-th by 2030 [strataphy.com/news, 2026] [The Green Circuit Substack, 2025]. To put that in perspective, the company has cited the Saudi national healthcare sector alone as representing a thermal cooling demand of approximately 3.45 gigawatts-thermal [strataphy.com/news, 2026]. Their total five-year target would cover about 1.5% of that single sector's need.
The recent $6 million seed round, led by Outliers VC with participation from Shorooq and PlusVC, is the fuel for this climb [Wamda, Nov 2025]. The capital is earmarked for advancing the PrimeLoop technology and expanding operations across Saudi Arabia and the UAE [Wamda, Nov 2025]. The investor mix signals confidence in both the deep-tech hardware and the service-based business model for the MENA region.
Where the geology gets tricky
For all its promise, Strataphy's model faces real-world friction that its seed round is meant to overcome. The risks are not trivial.
- Site-specific engineering. Every installation requires detailed geological assessment and custom engineering. The promise of working in "diverse geological formations" is also a challenge, as unexpected rock layers or groundwater can increase costs and timelines. Their proprietary tech must consistently tame this variability.
- The capex-to-opex sell. Convincing large, traditional industrial operators to adopt a subscription model for a critical utility like cooling requires a shift in procurement thinking. The long-term savings must overwhelmingly outweigh the comfort of owning depreciating assets.
- Scaling deployment. Moving from pilot projects to installing tens of megawatts of capacity means managing a fleet of drilling rigs and field crews. The operational complexity leaps from a technology startup to a specialized industrial contractor.
The company's most plausible answer to these risks is embedded in its team's experience and its service model. By owning the system, Strataphy absorbs the geological risk and the performance risk, aligning its incentives directly with the customer's. If the system doesn't save energy, Strataphy doesn't get paid. It's a high-stakes way to build trust in a new technology.
The incumbent in the crosshairs
Geothermal cooling isn't a new idea. Large-scale district cooling providers, like Saudi Arabia's own National Central Cooling Company (Tabreed), already operate massive chilled water networks for cities and gigaprojects. Their model is also a service, but it relies on centralized plants with conventional chillers. Strataphy's bet is that a decentralized, geothermal-based system can beat the efficiency and cost of those legacy thermal plants, especially for standalone industrial facilities or data center campuses that aren't on the district grid.
Do the math on a modest 5 MW-th installation. If geothermal cuts cooling electricity use by 50% compared to an efficient chiller plant, and local industrial power costs around $0.10 per kWh, the annual savings would be roughly $2.2 million in electricity costs alone. That's the economic headroom Strataphy is selling against. Their real competition isn't other geothermal startups. It's the entrenched economics of the industrial chiller, and the willingness of facility managers to let someone else drill holes on their property. The next twelve months will be about moving from a compelling data sheet to a signed contract with a name everyone recognizes.
