What GreenBrain Science does
The company operates a B2B software model built around sustainability measurement and optimisation. It packages multiple products for different digital environments: AI inference routing, ad supply chain emissions analytics, website carbon audits, mobile SDK-based footprint tracking, and desktop software emissions reporting. Value is created by embedding measurement into customer workflows, surfacing efficiency opportunities, and tying sustainability outcomes to spend, performance, or operational reporting.
Category differentiation
This is not a consumer green app or a pure ESG consultancy. It is a B2B software provider focused on digital carbon measurement and optimisation, including AI workload routing and ad supply chain analytics.
Strategic context
AI-supported assessment from the existing company research; distinguish interpretation from sourced facts.
GreenBrain Science is the commercial brand of Hiili S.L., a Spain-based spin-off linked to Universidad Carlos III de Madrid. It develops B2B software for measuring and reducing the carbon and energy footprint of digital systems, spanning generative AI workloads, advertising supply chains, websites, mobile apps, and desktop software. Its products are aimed at enterprise engineering teams, AI product teams, advertisers, agencies, publishers, IT teams, and sustainability functions. The company makes money through enterprise software sold as SaaS and SDK-enabled products. Its value proposition is operational rather than purely ESG-led: reducing infrastructure or media inefficiency, quantifying digital emissions, and supporting reporting and optimisation workflows. GreenBrain AI focuses on multi-model routing across foundation models to cut cost and carbon per prompt, while GreenBrain Media and the wider product suite provide measurement and optimisation analytics for digital channels and software estates.
Business model & monetisation
The company monetises primarily through SaaS subscriptions, with likely enterprise-tier pricing by deployment scope, data volume, or usage. API and SDK-based products such as GreenBrain AI and GreenBrain App likely add usage-based or licensing components. Commercial value is framed around operational savings, optimisation outcomes, and reporting capabilities, which supports value-based enterprise pricing alongside recurring software fees.
