Any good project must be based on sound fundamentals but to me what differentiate good projects that succeeded and those that do not is sound marketing behind their project, this is one thing in the space that is really lacking, what most of these projects rely on is using Twitter influencers and this can only do 1/10th of what needed to be done. Until this is looked into critically, not when you want to raise money but after the platform is up and running
Marketing/sales has two strategic approaches. One is a push, the other is pull.
Push entails force, very expensive, pull has your constituency driving demand.
I agree that marketing can be done after the product is running and so investors understand about the project to be invested. Fundamentals are important because they form the foundation of a project because fundamental analysis will determine how a company earns money and finances the project
