Biota develops faster PFAS monitoring and analysis technologies, combining a RapidTest screening platform that delivers results in about 15 minutes with MagnaPrep, a laboratory sample-preparation method using proprietary magnetic nanoparticle technology. The company is focused on accelerating PFAS analysis across both field and laboratory workflows and plans to expand its diagnostics platform to additional contaminants, including microplastics. Biota opened a 7,500-square-foot laboratory and innovation center in Longmont, Colorado to support product development, manufacturing, and customer deployments. It has received support from the National Institutes of Health's National Institute of Environmental Health Sciences and the State of Colorado's Advanced Industries Program, and participates in gener8tor's Great Lakes Innovation Accelerator and Imagine H2O's ecosystem. Financially, Biota recently completed a $3 million seed round to scale commercial deployment, sales, and customer operations.

CREW Carbon offers a process intensification solution for wastewater treatment that uses strategically-sourced alkaline minerals to optimize pH and alkalinity, improving biological performance, settleability, and plant capacity while permanently sequestering CO2. Since beginning commercial operations in 2024, CREW has deployed at nearly 10 facilities across the U.S. and Europe and secured long-term RFPs with utilities. The company has captured over 2,000 tons of CO2 and secured more than $33 million in carbon removal offtake agreements, delivering verified carbon removal credits to corporate buyers. CREW has developed proprietary measurement, reporting, and verification (MRV) capabilities and is developing a scalable analytics platform to provide operational insights and process optimization. Financial and strategic support from the Series A will be used to scale deployments, expand customer engagements, and add key hires in wastewater process, technology, supply chain, and business development.

Current Software provides a holistic utility billing and customer information platform designed for small- and mid-sized water utilities. The platform emphasizes rapid implementations (typically 6–10 weeks), an intuitive interface, field mobility, and an integrated customer portal. Since its seed close in October 2025, Current has deployed with 80 utilities across 16 states, demonstrating early traction. The company targets the ~45,000 U.S. water utilities with fewer than 10,000 service connections that largely rely on legacy on-premise systems. Current cites industry challenges including aging infrastructure, outdated software, and lengthy migrations as drivers of demand. The firm plans to use the seed proceeds to expand its team to reach more underserved utilities and accelerate product development based on customer feedback.

Founded in 2024 as a spin-out from FSubsea, Flocean develops patented modular systems that sit 400–600 meters below sea level, using natural hydrostatic pressure to cut capital costs by 7–8×, slash energy use by 50 %, and eliminate chemical pre-treatment. The company operates under a Build-Own-Operate model, selling water as a service to municipal and industrial customers through 15–25-year offtake agreements. It has already been desalinating water for 12 months at a test site in Mongstad Industrial Park and has secured preliminary project agreements with utilities across the Mediterranean, Red Sea and Indian Ocean regions. Flocean One, the first commercial subsea desalination plant, is slated to launch in 2026 at Mongstad and will produce 1,000 m³ of freshwater per day, with modules scalable to 5,000–50,000 m³ per day. The recent Series A extension brings total funding to $22.5 million, backed by strategic investor Xylem Inc. and several climate-tech investors. Proceeds will fund Flocean One’s deployment, expand the team, and accelerate commercial projects in Europe, the Middle East, the Americas, and island nations. The company positions its technology as a faster-to-deploy, lower-cost alternative to conventional seawater reverse-osmosis plants, targeting over 90 water-stressed coastal markets worldwide.
