This very website, Snowdrift.coop, is supported by its own crowdmatching mechanism!
Snowdrift currently has a crowd of 33 patrons. The current value of a pledge is $0.033, and the project's monthly income is $1.08. Of course, these numbers will change as the number of patrons changes.
We are currently working on improved explanations, videos, and web design to express the details and importance of our crowdmatching system and the value of public goods. We have much work to do finalizing a professional-quality user interface for the process not only of pledging but for projects signing up for the platform. We also have legal and structural work to do in building out the full co-op governance.
Although we hope to add a more standardized report eventually, we maintain a wiki page with an accounting summary so patrons can understand how we have used funds in the past and where any outside income comes from.
