Customers
Wave did sell some product to a few large accounts. Therefore, they do have something to sell. Why haven't any other large accounts bought anything? Concerning the financial state of Wave, absolutely, potential customers are scared away by it. I also have worked for companies that ran a D and B on any/all vendors, and I know that they would not touch Wave. Companies in better shape than Wave would have been vetoed. Anyone is blind to not realize this.
The damage has been done, and I do not know if it can be fixed or not. Perhaps, by a different management team; but that is probably not an option.
