This is Ex’tent
Ex'tent is the green venture capital company founded by the late Eckart Wintzen. Ex'tent was created to help stimulate the world's free market economy into a more sustainable direction. Ex'tent believes in a healthy society in which the need of welfare is satisfied by a virtual economy and more services rather than traditional materialism.
Since 2008 we are focusing on creating a 'wave' around Value Extracted Tax (Ex'tax in short), an idea inspired by Eckart. Ex'tax brings tax on resources up and tax on labor down. This enables sustainable prosperity, a type of prosperity based on smart resource use and an abundance of services. Please visit the Ex'tax website to find out more.
