About us

Aderize was founded on the vision that people and brands deserve better ads. 

And what a surprise, our ads resonate better with consumers resulting in much better ad performance. Now better ads aren't just about making the creatives look better. To get the creatives to load quicker while creating less traffic  advances had to be made in how the ads are delivered and how they are compressed. To reduce the amount of on-device power used we had to adopt different animation and interaction methods and to become carbon neutral we had to build our own modern ad server from the ground up. Being carbon neutral only answers half the challenge, we also had to make sure we were super efficient using the minimum power necessary. Then reporting had to be upgraded so that super rich metrics are available for all creative. 

 

Moving the needle on any one of these areas is a mammoth task and I’m so proud of all our contributors across our global team for achieving all this progress in just two and a half years.

 

In 2025 we are addressing the self service challenges that face Publishers and Advertisers alike and introducing new tools and services to ensure all have rapid access to brilliant creative without the traditional delays. We are also introducing new levels of dynamics especially for retail and Direct Response.
