Pioneers in Biogas Digitalization

Our software helps biogas & AD plants increase profitability by connecting operational data to financial outcomes.

As of 2026, our platform has supported hundreds of projects across 16 countries, spanning single-site operators to fleets of up to 40 plants. We work with Tier-1 operators and multinational energy companies, including CVE and TotalEnergies.

“We model the biology and the economics of every plant together. Over time, this turns into a fleet running on standardized analytics, with lender-grade LCOE accuracy and a defensible CI position.”

That unlocks equity growth, tightens debt spreads, and gets tier-1 lenders signing on to your next project. Our analytics layer revalues your biogas assets.”
