DK

DK runs a hybrid B2B model built around advertising-specific carbon measurement. It provides software for ongoing campaign analytics and reporting, an API for embedding carbon calculations into client systems, and managed audit and advisory services for customers needing implementation support or one-off assessments. The business creates value by turning fragmented campaign activity across digital and offline channels into standardised emissions metrics, reports and optimisation recommendations that can be used in sustainability reporting and media planning.

DK, legally Diploide, is a French B2B software company focused on measuring the carbon footprint of advertising campaigns across media channels. Its core offer combines a SaaS analytics platform, a calculation API and audit or consulting services for organisations that need campaign-level emissions data, reporting and reduction recommendations. The company appears to serve advertisers, agencies, publishers, ad sales houses and adtech firms.

DK makes money through recurring software subscriptions, API-based commercial usage and paid service engagements. Its value proposition is not media buying or sustainability branding; it is operational carbon measurement infrastructure tailored to advertising workflows, with integrations into adtech systems, dashboards and BI environments.
