We 100% agree that we need to have continual funding, and that this will not be feasible without transparency and updating our pledgers. Before we can define these things, we are waiting for one thing: To confirm a partnership with another group to fund a cause.
Once we can confirm whom we are funneling donations to, we will have an agreement in place with that group as to how we can be transparent and communicative to everyone involved. To some level, everyone that pledges will receive updates and information as to how their money is being spent.
That is to say information will be available to ALL pledgers, not just the upper levels. The upper level pledgers, however, will receive more frequent updates and some amount of input themselves.
We need to get better about communicating this on the site.
As for continual funding, we are looking into a model which funds in rounds, as you alluded to. But, again, we are waiting to meet our goal and confirm a partnership before we enter that realm.
We're extremely excited to see where this goes, and if you have any other thoughts please reach out to us! Our contact info's on the site.
