Variolytics

The company's core business revolves around helping wastewater treatment plants, which account for global greenhouse gas emissions comparable to the aviation industry, achieve climate neutrality. Variolytics offers a combination of patented hardware and AI-powered software to monitor and reduce harmful emissions, particularly nitrous oxide (N₂O), which is significantly more potent than carbon dioxide. Its primary product, the EmiCo system, provides real-time, high-accuracy measurement of gases like N₂O and methane in both the gas and liquid phases within aeration tanks. This data allows plant operators to dynamically control and optimize processes, leading to reductions in greenhouse gas production, energy consumption, and chemical usage. The system features auto-calibration to prevent measurement drift and can monitor multiple aeration basins concurrently.

The business model includes selling hardware products, such as the 'Vario one' and 'Vario two' analyzers, and providing software services and tailored emission monitoring services. The technology is designed for seamless integration with existing process control systems. Variolytics serves municipal wastewater treatment plants and has formed strategic alliances, such as with Glanua, to distribute its solutions in the UK and Irish markets. The company has successfully raised capital through multiple funding rounds, including a seed round in 2022 and a growth financing round in 2025 led by investors like Nordic Alpha Partners, High-Tech Gründerfonds (HTGF), and the European Innovation Council (EIC).
