They not always have to do Development but they have to look for the price & also they will getting investor for their.i know they already got whatever investors they need
I'm not sure about it though but they truly need an effort to the investors so the investors think they are not having a kind of unworthy investment.
Yes effort is highly recommended, it is not all about developing but both should go together. The team should look each side in order to succeed. They should learn to hear each sides in order to have a positive sorroundings which is very important. Looking forward for more success in this project.
