About InfoSum

InfoSum is a technology startup that operates in the data collaboration and privacy sector. The company provides a secure platform, known as a Secure Data Clean Room, that allows businesses to collaborate on data-driven strategies while ensuring end-to-end privacy protection. This platform is trusted by global companies to deliver better data-driven experiences, helping them to increase performance and protect their business reputation.

InfoSum's clients range from marketing and advertising firms to large corporations that need to leverage their first-party data while maintaining customer privacy. The company's business model is centered around providing a solution that allows these businesses to safely and effectively collaborate on data without physically moving it, a concept they refer to as 'non-movement of data'. This approach allows businesses to match their audience with other companies' customers in a privacy-first way, which can lead to increased acquisitions, reduced costs, and boosted match rates.

The company generates revenue by charging businesses for the use of their Secure Data Clean Room platform. This platform not only provides a secure environment for data collaboration but also allows businesses to calculate the true impact and value of their data-driven strategies.

InfoSum positions itself as a champion of data privacy, believing it to be a basic customer right. Their platform is designed with privacy in mind, enabling collaboration without compromising on this principle. This focus on privacy, combined with the ability to deliver relevant experiences to customers, makes InfoSum a valuable partner for businesses looking to maximize their return on investment (ROI) while respecting their customers' privacy.
