About InfoSum

Today, data protection and data privacy are primary concerns of businesses of all sizes due to the costly consequences of data breaches. InfoSum aims to alleviate security concerns by building a decentralised solution that allows secure data sharing between organisations.

The innovation of InfoSum comes from its creation of a decentralised method based on patented technology through which companies can share their data with other companies without passing it on to each other. The technology connects customer records between organisations, without moving or sharing data, so InfoSum's solution is compliant with all current privacy laws.

InfoSum wants to capitalise on the opportunity provided by the growing demand for privacy-focused tools and software. Recognising its vision, multinational communications and tech company WPP acquired InfoSum in 2025. InfoSum counts AT&T, Disney, Omnicom, and Merkle among its clients, and its acquisition will further expand its market reach.
