Secure data sharing without compromising consumer privacy.

Welcome to Karlsgate

We’re data scientists and technologists who, for over two decades, have wrestled with a major conflict in the industry. Our appetite for consumer data to drive insights and competitive advantage has outstripped our ability to share it in a safe and privacy-compliant way. Self-regulation isn’t working, and the data economy is broken. We founded Karlsgate to fix it.

Our Approach

Sharing Personal Data isn’t required to get consumer data necessary to deliver meaningful brand experiences. Using Personal Data is just the easiest way to bridge two data sets.

The industry has tried to protect data. But hashing, clean rooms and encrypted transport don’t solve the problem. Personal Data is still being moved around the digital marketing ecosystem. This leaves consumer identities open to exposure of persistency, theft and re-identification.

That’s why we created Karlsgate Identity Exchange™. It’s a zero-trust data sharing platform. Using Cryptoidentity, a patented encryption process, brands can restart the flow of data with safe, peer-to-peer collaboration without ever exposing Personal Data.

Karlsgate is ushering in The Protected Data Age. We are powering the data economy with the free-flowing, responsible and irrefutably safe handling of consumer information.

No custody

No disclosure
