How about just... starting a regular IT business?
I have chosen the general market I would like to work with.
Now I would like to identify the main problems in this market.
I am talking with people who would be using my software, but ultimately it's supposed to be a b2b solution, so it would be super-valuable for me to talk with actual businesses about their issues, problems and current solutions they are using?
Has anyone here did this successfully? That is establish firm business contacts without even having the product in the first place? Any suggestions how to approach that problem?
I have a fear that I will not be treated seriously without some kind of "organization" being behind me, or established portfolio.
Currently I have cold-emailed few companies as an experiment. It's too early to know what will be the results.
