While I believe you are correct that co-ops are not a great fit for the growth business strategy that VCs make their bread and butter on, I believe that on many metrics co-ops tend to be more sustainable than the corporate alternatives[0]. This means they are more likely to be around tomorrow to pay off a loan.
All this to say, it would be great to see more capital for co-ops in the form of traditional loans with favourable interest rates.
