Finding investors for a project no matter real world project or online project is not easy task to do. You need to offer something good but reasonable for possible investors, you also need to have clear information about the project such as your team identity, your plan/roadmap of the project, etc. Too many aspect to be mentioned but you can learn from successful investment. Learn what they offer, what they do, and how they manage the offers.
It takes time before finding real investors and supporters of a project. Specially right now that most of projects in online world that applies for fundraising or conducting an ICO failed to give the credit and benefits to the investors. In fact, there are times that they failed to back the money because of market conditions or scam projects.
That is why real investors is hardly to see. They want to have assurance that what they give is what they get.
if the project has a good marketing strategy to make investors interested I don't think it's necessary to worry,
it all depends on their team, some go through the real world by making public events
