Once your ICO is well settled into the Public ICO stage, setup an AMA session with the CEO and other key members. Being asked hard technical questions and your vision and development is the best thing that can happen to you. If you satisfy people with your answers then you can win a lot of retail investors.

Also search for ICO pools who can help you get some early investors.
