I am "patent-pending" on a music related product that I intend to bring to market.
I am curious to find out how common or uncommon it might be for a marketing firm to get involved with a product on the bottom floor in exchange for either a share of revenue or for equity in our LLC.
By bottom floor, I mean prior to looking for venture capital or having a tangible retail-ready product.
If situations like that are possible (even if they are uncommon) - are there any advantages to attempting to go that route at this stage?
If viability of the product is a factor, I've put together a short video presentation that describes the product and everything else in detail - though I would rather just go under the assumption that this is a ground-breaking product for the sake of this question.
Here is the link to the video: http://www.blackclouddigital.com/
Any info about the marketing companies or opinions on the product itself would be a huge help.
Thanks!
