Our Mission

Our Mission

To promote and sustain a robust timebanking infrastructure which supports non-monetary transactions amongst individuals and organizations allowing a greater sum of the realized value of work to be retained and shared within local communities.

Our Vision

To make social infrastructure visible within our communities. Social infrastructure describes the invisible bonds and relationships which constitute a generative capital that can be accumulated and circulated through timebanking. 

Our Goals

  • To improve the quality of life of members by linking them to a high value citywide database of skills and human assets.
  • To increase the accessibility of local skills pools to individuals, small businesses and community based organizations.
  • To develop and sustain a complementary community currency which decreases financial pressure, reinforces the fabric of trust and creates new opportunities for engagement between stakeholders within communities.
  • To develop a co-production pipeline which enables more agile delivery of human and social services by linking some recipients directly to services provided by members in their local communities.


Five Core Values

While time based exchange systems have existed as far back as the early 19th century, Edgar Cahn of Timebanks USA is most often credited with its late 20th century revitalization introducing such terms as “time dollar”, “time bank” and “time credit” into our parlance with his 1992 text, “Time Dollars”.

He later went on to define four core values of co-production in his 2000 publication, “No More Throw-Away People” to which he later added a fifth value.  These values now form the ethical foundation of timebanks throughout the world.


Every person is an asset. Everyone has something of value to share with another member of their community. Every person has a contribution which they can make towards making their community a more resilient, trusting and healthy environment. We approach timebanking from this asset based perspective because it allows us to meet the whole person in our interactions.

Redefining Work

Some work is beyond a market price. The market economy has placed a premium on specific types of work and undervalued others. Money is not is not attracted to work which restores families, improves communities, engages democracy or shifts our society towards more socially just outcomes. Timebanking is designed to be a system which allows a community to develop a local economy centered in its own values and assign value to the things it deems significant or impactful.


Giving works better when there is a mutual contribution and benefit to the exchange. The benefit may not be immediately reciprocated to the giver as in a barter transaction, but redounds to the whole community when a previous recipient now has an opportunity to become a giver. In timebanking, we pay our gratitude forward rather than paying it back. Through reciprocity, we shift from being volunteers offering unilateral acts of charity to stakeholders in community acknowledging that our fates are intertwined with those we are helping. 

Social Networks

We need each other. Vibrant communities are built on the foundation of deeply rooted social networks. Networks are stronger than individual citizens. We can access this collective strength by pooling our unique skills and intangible assets in a space where members of our local communities may engage with them more readily. Through timebanking, we can reestablish a social infrastructure grounded in mutual support, strength and trust which becomes a social safety net scaleable enough to bridge the gaps in each of our communities. 


 Every person matters. In the construction of just, democratic and community oriented spaces, we strive to honor this value of respect by being thoughtful, sympathetic and reflective in how we deal with one another. I am not who I was yesterday and I may not be who I am now tomorrow. We respect the journey that each member of our community must take and commit to build a supportive social infrastructure around each member to aid them in their journey.
