Seedtag: sovereignty score and 8 European alternatives

Seedtag is an advertising technology company that sells contextual display, online video and connected TV advertising. Its platform places ads according to the content of the pages where they appear, using an AI layer the company calls Liz. Advertisers and agencies use its tools to manage campaigns, select inventory and monitor brand safety. The service is delivered as an online software platform.

Seedtag Advertising S.L. is registered in Madrid, Spain, so the company is headquartered in the EU. The pages reviewed do not state its shareholders or where customer data is hosted, and no GDPR statement was found on the homepage. A European organisation should therefore ask for the data processing terms, the sub-processor list and the hosting locations before using the platform, because the service runs on the vendor's infrastructure.

Why digital sovereignty matters with Seedtag

Seedtag is headquartered in ES and therefore falls under European law: the GDPR, NIS2 and the Data Act. No foreign legislation can compel access to your data.

Data is hosted exclusively in the EU, so Seedtag scores best on data residency.

Seedtag is closed source and hosted by the vendor. The encryption keys and the runtime sit with the vendor and switching requires data migration. Ask about bring-your-own-key, export options and open standards.

What this means for your organisation depends on your whole stack and context. The free assessment weighs Seedtag together with your other vendors and gives a total score, a heatmap and the main risk drivers.
