Personal Data is precious currency.

Personal Data

Expressions, Search, Photos, Environment, Calendar, Interactions, Activities, Location, Spending

Transformed to signals

Interests, priorities, preferences


Give recommendations, nudges, personalisation


 Personal Data is scarce

Challenges in getting real-time, on-demand, dynamic personal data at SCALE

Economically Risky

Regulatory environment in Europe


Coding every OPD APIs into your app/service


Potentially erodes credibility & trust


Constant duplication of personal data across apps and websites create security and privacy risks

Low Quality

Doesn’t provide insights or signals in real-time, on-demand
and dynamically updated unless through a data broker (costly)


The Solution

Organisations should give their customers a HAT

When their customers own the legal rights to their data on the HAT, they can be able to give real time, on demand permissions for every context of data usage if and when they arise


The HAT is a decentralised “microserver” that enable individuals to legally own rights to their data. HAT microservers enable personal data storage, processing, AI and exchange and become the Universal Data Profile of an individual


How HATDeX can help firms 

HATDeX built and operate the first scalable personal data exchange platform between individuals and corporates using open sourced decentralised HATs.


Firms can pay for HATs issued, or pay only when inquire or acquire personal data from their customers. The more they exchange data, the less they pay for HATs


From the acquiring model....

Previously, individuals interact with apps directly and give their data away each time. Although they get a good service in return, they do not get to keep their data and so they cannot re-use or re-share with other apps.


Instead, the apps acquire the data from others and share amongst themselves, with users consent


To the inquiring model

With a HAT micro server, HAT owners get to keep the data and can re-use and re-share the data with other apps on demand


Since the HAT is API-based, corporations can build in the ability for the individual to operate the microservices in the HAT within their own app to inquire data, with permission, as and when needed, without having to store the data 


Single sign-on

If you are a website or application : you can give your customers a HAT and ask for more data to personalise your website with a single sign on, and without the risk of holding personal data. Find out more at
