My experience shows that in order to succeed you need: 1) someone who knows marketing in the area you are targeting (medical equipment marketing is not the same as, say, cat hairdresser marketing or dev tools marketing); 2) someone who will sell - yes, a salesman, a person who likes to talk to customers, call people and knows how to sell stuff in your target group. I am not talking here about building all those famed sturtups created by 3 "scratch your own itch" techies in the cellar and that succeeded by pure chance or thanks to connections founders had or other factors that average indie founder cannot control. If you are indie dev, you should not make yourself dependent on luck or accident. Start with this: marketing guy, who knows the market, such person in two hours can invalidate your idea and give you 5 better ones. Learn some marketing stuff by yourself (books like Start Small, Stay Small will not make you rich in a day, but will open your eyes to the way things are working, most of this is obvious once you read it, but this is psychological "I knew that all along" phenomena - although you somehow knew this, you were not using this. Same with sales, stuff will not magically sell by itself. You can count that your product will become "viral" or something, but, again, you make yourself dependent on chance. Just have someone who will help you do the stuff, you are not that great at.
