We need to change the Internet.

It's leaky, it's invasive, it's inefficient, and it's a bit manipulative. Our personal data and our online habits are too often exposed to hackers and advertisers, and the companies that want to use our data are often ignorant and sometimes malicious in how they do so. We shouldn't be satisfied by that - not when tech CEOs are being dragged in front of US Congress.

One of the ways we can fix the Internet is to give people more power and control when they're online. Power and control come primarily from technologies today, and that technology gets all its power and control from data. Until now it's been the companies that built all that data infrastructure. Now people can have some too, with a "HAT microserver."

HATs are private and ownable by the individual, and they let people own their own personal data as well as draw on AI tools to gain insights from their personal data. They can also be used to create new apps that have HATs as a user account, increasing the value of the person online so that everybody wins. HAT owners get more powerful, and the technologies and companies they care about do too.

More than 1300 HATs have been created to date. They're owned by the users of our apps, and the apps of the dozen+ corporate partners that currently build on our technology, customers that include Tata Motors UK, Good-Loop social advertising, Bear Health personal medical records, and more.
