Addingwell's server-side expertise, backed by Didomi's privacy leadership. Since its acquisition by Didomi in 2025, Addingwell combines best-in-class server-side tagging with a reference-grade consent management platform.

Together, we help enterprises reconcile marketing performance, data quality, and compliance. Visualize in real time the consent attached to every request, and stay in control of your data flows from collection to activation.

More about Event Consent Monitoring

Your AI
is only as good as the data you feed it.

Algorithms need complete data, not approximate data. Google Performance Max, Meta Advantage+, and programmatic platforms calibrate bids and audiences based on the conversion signals you send. Every missing event is a miscalibration. Server-side tagging restores the full signal so your algorithms compete on real data.
