Hiili

The company operates an enterprise-focused platform for measuring and managing carbon and energy use across digital channels. It creates value by collecting technical telemetry (e.g. web requests, ad-serving data, app and desktop events, API calls to AI models), applying measurement methodologies and machine learning-based models to estimate energy consumption and associated emissions, and then presenting this data through reports, dashboards, certifications and optimisation recommendations. The portfolio spans tooling for websites, digital advertising supply chains, mobile and desktop software, and generative AI infrastructure, allowing customers to benchmark, attribute and reduce digital emissions.

Revenue is primarily generated through software access and analytics services: subscription or licence-based access to its measurement and reporting products; SDK-based instrumentation for mobile; and routing/analytics services for generative AI operations. Professional services such as audits, enterprise rollout support, integration assistance and certification deliverables likely complement the software products, especially for larger organisations that need tailored implementations and formal reporting for ESG and sustainability programmes.

Hiili.org (Hiili S.L.) is a Spain-based spin-off from Universidad Carlos III de Madrid and media/advertising industry veterans that develops technology to measure and reduce the carbon footprint of digital activities. Its core platform provides carbon and energy measurement across websites, online advertising, mobile applications, desktop software and generative AI workloads, using internet measurement techniques and machine learning models.

The company monetises by offering enterprise-focused software and analytics services, including a website footprint reporting product, an advertising emissions measurement tool, SDK-based mobile tracking, desktop telemetry and a routing layer for generative AI models that optimises for cost and carbon. Direct customers are organisations such as advertisers, agencies, publishers, enterprises, public entities and companies with digital estates that need quantified emissions data for ESG reporting and operational optimisation.
