Digiseg Vision and Mission
– for ethical audience data
We envision a world where ad-tech serves humankind and works in the service of truth.
Digital tracking, echo chambers, fake news, and walled gardens that traffic human decisioning-power must end. Ultimately, press-accredited media, investigative journalism, democracy, and free will are at stake.
Our team’s goal is to enable advertisers to target consumers in a tracking-free manner while achieving similar or better returns on advertising spend as the walled-gardens’ highly invasive approaches.
We’ll know we’ve reached our goal when the majority of digital campaigns are neither measured nor targeted using personal data and tracking.
