Our take

With the likes of Meta, Amazon, and Google hosting the majority of ad campaigns, contemporary strategies can become overly complicated and lacking in owner control. Topsort has created a simple and customizable API through which users can create advertising elements like sponsored listings, banner and video ads, and control how they’re shown to potential customers.

Where the platform stands out is in its transparency and privacy-first approach - delivering a direct replacement of the “cookie” system usually used in sponsored ads. Topsort’s “clean room” is an encrypted technology that has zero-visibility into privacy data, ensuring anonymity for those being analysed.

This exciting new approach to media marketing analysis and campaign planning has turned investors' heads, at a time when data privacy is a hot topic. Topsort has enjoyed an impressive $21M in funding to date, which will it is using to scale and accelerate its growth.
