About Fetch.AI

Fetch.AI is building the technology and tools to support this exciting vision of the next generation of economic activity. There are a great number of ways to participate in this ground-breaking project.

Develop agents and new applications Developers

Fetch will be providing a comprehensive SDK allowing the development of agents in languages such as C++ and Python as well as a set of frameworks to allow web developers to design, configure and author agents. Agents are able to explore the Fetch decentralised digital world looking for opportunities to deliver their value to others, or gather relevant value for themselves. Developing this next generation of economic agents is an opportunity for emerging and new economic models and Fetch will be supporting developers in this work.

The founding team has worked together on AI and its application in autonomous systems for the last 3 years. It has further spent over a year partnered with world leading economists and professors from Cambridge University, Sheffield University, Imperial College and Outlier Ventures on building open economic frameworks underpinned with crypto assets and DLT.
