Enaxiom, a data center water use startup founded in 2023, has closed a $2.5 million seed round led by Singapore-based Epic Angels. The funds will support commercial deployment of their Hydrocool system, boost headcount, and accelerate growth in the US market.
- Raised $2.5M seed round led by Epic Angels
- Focus on water-efficient heat rejection cooling tech
- Plans to expand commercially and increase US presence
What happened
Enaxiom, a Sydney-based startup founded by Bijan Rahimi and Tia Collings in 2023, has completed a $2.5 million seed funding round. The round was led by the Singapore-based all-female investment collective Epic Angels, with participation from BlackNova and Antler. This brings Enaxiom's total funding to approximately $2.7 million USD.
The startup is advancing its patented data center cooling technology, Hydrocool, which focuses on heat rejection by utilizing non-potable and wastewater streams. Following a successful 40kW pilot proving the concept, Enaxiom plans to develop modular systems ready for commercial-scale deployment and expand its operations in the US.
Why it matters
Water scarcity is emerging as a significant constraint for data center infrastructure, especially as AI computing demand grows rapidly. Traditional cooling methods consume large volumes of potable water, underscoring the need for more sustainable solutions. Enaxiom’s technology reduces potable water use by recovering high-quality water during cooling.
By focusing on the heat rejection stage—a critical but often overlooked component of cooling systems—Enaxiom enhances compatibility with advanced liquid cooling methods such as direct-to-chip and immersion cooling. Their approach could reshape how water consumption is managed in data centers, improving environmental sustainability across a growing industry.
What to watch next
Enaxiom's progress in scaling its Hydrocool system from pilot to commercial modular units will be a key indicator of market adoption. Its ability to integrate with emerging liquid cooling technologies will also determine its penetration in the competitive data center infrastructure sector.
Additionally, the company's planned expansion into the US market will be crucial to watch, as this region represents a major hub for AI infrastructure growth and data center investment. The involvement of Epic Angels highlights a growing trend of supporting female-led startups in deep tech fields, potentially paving the way for more diverse leadership in sustainability tech.
