InfoSum enables privacy-safe analysis and activation by allowing first- and second-party data to be connected without sharing or centralizing raw data. Instead of moving data, the platform uses secure environments called Bunkers, where anonymous mathematical representations of data are generated. These representations are exchanged between Bunkers and tested to identify overlaps, such as whether the same individuals exist across datasets, without revealing personal information. This approach allows advertisers and partners to conduct cross-dataset statistical analysis, answer targeting and measurement queries, and gain insights while maintaining strict data security and privacy controls.
