Capital and partnership for the next generation of water systems
Aquius Capital invests in companies that are building more resilient, efficient, and sustainable water solutions. We partner with founders to help proven technologies scale in the real world.
Why Aquius
Water is becoming one of the defining constraints of the global economy. Scarcity, pollution, and climate disruption are no longer distant risks. They are shaping supply chains, infrastructure, and long-term value today.
Aquius exists to back the entrepreneurs and companies that help society to adapt to and mitigate the risks of this new reality
For Investors
Water is moving from an overlooked resource to a strategic asset. A market worth more than $800 billion* is being reshaped, yet capital remains underallocated to water innovation.
Aquius offers access to a highly specialised platform, a deep sector network, and opportunities to invest in companies with both financial upside and measurable impact.

For Founders
Building in water is hard. Technologies must perform in complex environments, markets are fragmented, and scaling depends on trust, validation, and system integration.
Aquius partners with growth-stage companies ready to move from proven technology to commercial scale.
What We Look For
We invest in early growth-stage companies with proven technologies, protected IP, initial traction, and clear real-world use cases.
Our focus includes water quality, efficiency, and circularity, hydrological resilience and ecosystem restoration, and the water–energy nexus.
How we help
Aquius is an active partner from day one. We connect founders to utilities, industrial players, and research partners. We support pilot development, regulatory navigation, commercial strategy, and preparation for the next funding round or strategic acquisition.
Our goal is to help strong solutions scale faster.
Shared Mission
We believe the strongest companies are built where commercial success and systemic impact reinforce each other.
By backing the right founders and partnering with the right investors, we can help restore balance to the global water cycle.
