and from your letter:
The typical budget of a new specialty food product is 30k - 100k per year total, and almost all of that is allocated for manufacturing/distribution/development/salaries, so the marketing budget at these companies is basically zero.
You've got some unstated/hidden assumptions that I am trying to illuminate.
Why do you believe the actually selling and distribution method of a new product doesn't fall into the list of "critical things founders need to know how to do to have a successful business" and instead can be outsourced?
You built a "selling" product for founders who don't know how "to sell" in the first place, I don't think there should be surprise that it failed. Just my .02
