Where I live, all it requires is filling in forms and paying a fee to the state. I'm sure laws vary. What was your hurdle?Did you incorporate an LLC? No, I tried but I couldn't
Did your research identify some market segment - customer group - that needs your product? Did you identify the competitive products and find attributes of your product that make it "better" in the eyes of those customers? Did your research give you guidance on your target pricing?Did you do your market research? Yes
My main point is that market research is not something you can ever say you "did". It's always ongoing and there are always more questions to answer. The more you know about the market landscape, the more you can adapt and carve out the opportunities. Having great technology looking for a buyer is rarely effective.
