Millions of dollars flowing through your platform and you can't monetize it? You can't monetize the website, but you expect to be able to monetize on mobile? Those seem like major disconnects to me. Any investor you approach would think the same thing.

Are you a marketplace like Etsy? If so, several smaller versions have already pivoted their businesses. You may be heading in the same direction.

It sounds like an interesting problem. If you'd like to discuss in more detail, I'd be happy to look at the model and see if mobile makes sense. We can also talk about ways of getting a mobile platform created for less than building a native version from scratch.
