A typical web-app startup isn't for me at this point indeed. I don't want to create a company from get-go. I want to create the science (hardware+software+new algo) first, spend 6-12 months working on it with my target users, and then once it is functional, make it a product. I can't do this part-time. I have to do this full-time but I can work part-time (consulting etc.)

I will have sufficient savings soon. For me it's not a question of if but when. It is the wait that's killing me. And then I see questions like this that make me feel even more impatient. But I truly appreciate such questions. Keeps me steadfast.
