We are building the foundations for a decentralised society.

Current Projects


WikiHouse is an open source construction set that enables anyone to design, download, print and assemble a house. Founded in collaboration with Architecture 00, the WikiHouse project now has more than 30 chapters in cities around the world and a TED talk with over a million views.


We are developing WikiFactory to enable design and hardware projects to collaborate as effectively as open source software projects. The in-browser, open source platform will feature a library of 3D designs and an easy-to-use design tool so that anyone can create, share and modify designs for digital fabrication.


Ampify is an open source, decentralised application platform that we are building. It will provide a framework to create social apps on top of a secure, decentralised core.

Selected Past Projects


Community Crowdsourcing

Built in collaboration with our friends at Architecture 00, the Civic Crowd is a community action platform which enables people to map, collaborate and drive positive change in their area.

It enables people to share their projects, discuss ideas, offer their skills, appreciate projects, propose actions and volunteer to turn proposals into reality. It also provides community organisers with the tools to manage their projects and crowd source support and funding.

The platform now also powers the Greater London Authority’s Open Institute project.




Social Business Incubation

Social Startup Labs are standalone, 1-day workshops at which local enterprise ideas are generated and acted upon.

We partnered with London Creative Labs to offer these intense but fun one-day workshops where participants brainstorm, learn, and network with one purpose in mind: to create new businesses that can create work for local people and contribute to sustainable regeneration.

The events drew a divere range of stakeholders, to effectively identify new opportunities for local value generation.


Reputation Systems

Building on our earlier concept of trust maps from Xnet, in 2009 we built the Espra Trustmap, a web service for mapping trust and reputation.

By utilising APIs and integrating with other ID structures and social networks like Twitter or Facebook, Trustmap allows users to easily build a map of people they trust for specific subjects which enables the delivery of semantically rich data streams, such as search results or incoming stream filtered through your social networks.




Video Streaming

In 2006 we built Green TV, the worlds first online broadband TV channel for environmental content.

Co-founded with Large Blue and with support from UNEP, Greenpeace and Friends of the Earth, Espians built the underlying architecture for the original Green TV platform.

Today it delivers 1/2 million video views a month for media partners including Sony, iTunes, Aol, blinkx and the Huffington Post.


Co-Working Spaces

In 2005, we joined the original Impact Hub Islington, a network and co-working space focused on making a positive impact in the world.

Our members were instrumental in founding the global network of hubs, managing the technical infrastructure and collaborating on organisational development and most recently, founding the Hub Westminster.

Today there are over 50 HUBS with over 7000 members on 6 continents.




Gift Economy and Micro-Payments

In 2001 we designed a system called Espra File Sharing, which was built on top of Freenet, as an early P2P anonymous file sharing network.

Espra provided a fully integrated online media player for all types of music files and a micro-payment feature which allowed members to tip musicians, both extremely novel features in 2001.

Over 50 artists uploaded their music to the public domain and thousands of pounds flowed through to musicians.


Collaborative Decision Making

Originally conceived in 2000, Xnet is a collaborative decision making and participative budgeting tool that enables open organisations to define their organisational structure, manage project resources, keep up to date with who’s working on what and make intelligent, democratic decisions.

Discovering Wikis led to a new implementation of Xnet with a more open architecture and greater functionality (incorporating trust maps, jabber, VOIP, etc) as a web based collaboration system used internally between Espians.




Crypto Currencies

Originating as early as 1999, Pecus are an Espian model for an alternative, reputation based currency, which were incorporated into the Xnet project.

More recently we incorporated much of the thinking behind Pecus into Open Coin, an early open source implementation of Chaum anonymous electronic cash.

In 2012 we developed the Open Coin crypto currency as a framework, defining open protocols for exchange of electronic cash, and implemented an iOS based Wallet.
