InfoSum, a London-based startup that provides a decentralized platform for secure data sharing between organizations, has secured a $65 million Series B funding round led by Chrysalis Investments.

The investment comes less than a year after InfoSum closed a $15.1 million Series A round co-led by Upfront Ventures and IA Ventures. Since, the data privacy startup has tripled its revenue, doubled its employee base, and secured more than fifty new customers, including AT&T, Disney, Omnicom and Merkle.

Its growth was boosted by businesses that are increasingly focused on data privacy, largely as a result of the mass shift to remote working and cloud-based collaboration necessitated by the pandemic. InfoSum’s data collaboration platform uses patented technology to connect customer records between and amongst companies, without moving or sharing data. It helps organizations to alleviate security concerns, according to the startup, and is compliant with all current privacy laws, including GDPR.

The platform was bolstered earlier this year with the launch of InfoSum Bridge, a product which it claims significantly expands the customer identity linking capabilities of its platform. It is designed to connect advertising identifiers along with its own “bunkered” data sets to better facilitate ad targeting based on first-party data.

“The technology that enables companies to safely and securely compare customer data is thankfully entering a new phase, driven by privacy-conscious consumers and companies focused on value and control. InfoSum is proud to be leading the way,” said Brian Lesser, chairman and CEO of InfoSum. “Companies are looking for solutions to help resolve the existing friction and inefficiencies around data collaboration, and InfoSum is the company to drive this growth forward.”

The company, which says it is poised for “exponential growth” in 2021 as businesses continue to embrace privacy-focused tools and software, will use the newly raised investment to accelerate hiring across every aspect of its business, expand into new regions, and further the development of its platform.

Nick Halstead, who previously founded and led big data startup DataSift, founded InfoSum (then called CognitiveLogic) in 2015 with a vision to connect the world’s data without ever sharing it. The company currently has 80 employees spread across offices in the U.S., the U.K., and Germany.
