Crew Carbon Raises $25M in Series A and Grants

The $25 million funding round included $19 million in Series A equity financing and $6 million from grants and other non-dilutive funding sources.

The company plans to use the funding to expand its operations and continue developing its technology and products.

CREW has developed patented technology that helps utilities improve the performance of existing wastewater infrastructure. The solution increases pollutant removal, improves settling performance, and reduces the need for expensive chemicals, helping utilities lower operating and capital costs while reducing pressure on ratepayers.

Because the technology works within existing wastewater systems, utilities can see results within weeks. CREW has already secured several long-term utility contracts across the United States.

CREW uses alkaline minerals, such as calcium carbonate, to improve wastewater treatment conditions, including pH and alkalinity. Its technology helps treatment plants perform better while permanently capturing CO2 and other harmful emissions using existing industrial infrastructure, without relying on major government funding or special permitting.

The company has already delivered verified carbon removal credits through long-term agreements with organizations including JPMorgan Chase, Google, Autodesk, and Stripe, through Frontier, along with other long-term carbon credit agreements. Demand for measurable engineered carbon removal solutions continues to grow as companies pursue net-zero goals.

"We are pleased to welcome CREW to our portfolio," said Andrew Hinkly, Managing Partner at AP Ventures. "CREW has impressed us with its rapid progress, ability to deliver real carbon dioxide removal, and high quality, low-cost approach to CDR. The team is focused on executing a clear go‑to‑market strategy that leverages existing industrial infrastructure, and well‑defined customer pain points to unlock decarbonisation at scale. CREW is advancing quickly and we look forward to supporting their continued growth."

"Startups advancing frontier technologies to tackle global environmental challenges are central to building more sustainable, resilient industries – and a key focus of Sony Innovation Fund's investment strategy," said Austin Noronha, Managing Director, Sony Ventures-US. "CREW combines deep geochemistry expertise with a pragmatic business approach to seamlessly integrate carbon capture into existing infrastructure, making it both scalable and commercially viable. With multiple deployments already underway, CREW is well-positioned to help various industries accelerate decarbonization."

"CREW's water technology is driving jaw-dropping results for wastewater customers," said Tom Ferguson, Partner at Burnt Island Ventures. "On top of the improvements they deliver to wastewater utilities, CREW's precise measurement of permanent carbon removal is highly differentiated in the crediting market and empowers carbon credit buyers to know exactly what they are paying for. Together, CREW's technology and business model are aligning good environmental outcomes with the bottom line for a massively impactful industry."
