CREW Raises $25M of Funding to Scale Wastewater Treatment Optimization Technology as Climate Solution

Water technology company CREW Carbon, Inc. has successfully closed an oversubscribed Series A funding round, raising a total of $25 million. The funding round, which took place in May 2026, was led by Burnt Island Ventures and included participation from a diverse group of investors, such as AP Ventures, Sony Innovation Fund, Builders Vision, Kibo Invest, Idemitsu Ventures, New York Ventures, and several family offices. The financing consists of $19 million in equity and $6 million in non-dilutive funding, aimed at deploying CREW's patented wastewater treatment technology across additional wastewater utilities.

CREW Carbon specializes in innovative solutions for the wastewater treatment sector, which has been grappling with increasing regulatory pressures and the challenges posed by aging infrastructure. Over the past two decades, treatment costs have doubled, necessitating the need for efficient, cost-effective solutions that can enhance the performance of existing systems. CREW's technology stands out by enabling utilities to optimize their current infrastructure without the burden of significant capital investments. The company's approach not only improves pollutant removal and boosts settleability but also reduces reliance on expensive chemicals, ultimately leading to lower operational costs and easing the financial burden on ratepayers.

The strategic rationale behind CREW's technology lies in its dual capability to enhance wastewater treatment efficiency while also achieving carbon dioxide removal. By utilizing strategically sourced alkaline minerals, such as calcium carbonate, CREW optimizes key conditions in the treatment process, resulting in better biological performance and the permanent sequestration of CO2. This innovative method allows utilities to see measurable improvements within weeks of implementation, making it an attractive option for municipalities and utility operators facing urgent operational challenges.

The funding secured in this Series A round positions CREW to expand its market presence significantly. With nearly ten deployments across the U.S. and Europe, including partnerships with leading utilities, the company has already demonstrated its ability to deliver measurable performance improvements. Notably, one utility is considering deferring a $350 million capital upgrade due to the efficiencies gained through CREW's technology. Additionally, CREW has established long-term agreements for carbon removal credits with major corporations, including JP Morgan and Google, further validating its market proposition.

As the water technology sector continues to evolve, CREW's successful fundraising underscores a growing investor interest in solutions that address both environmental sustainability and operational efficiency. The company's focus on integrating carbon capture into existing wastewater treatment processes aligns with broader industry trends emphasizing decarbonization and resource optimization. With the increasing importance of carbon credits in achieving net-zero goals, CREW is well-positioned to play a pivotal role in transforming the wastewater treatment landscape, ultimately contributing to more sustainable and resilient infrastructure in the face of climate change challenges.
