Creating an automated platform for ICO / IPO is not trivial, as this type of project typically requires involvement of investment bank.
Besides tech stack you'll need PR (otherwise noone will now that your ICO is happening), Legal (to structure your financial instrument properly), industry insiders (to attrack target group of investors) and a lot of other people.

At Ambisafe (http://ambisafe.co/) we have the full tech stack that typical ICO requires and can connect you with the rest of the partners that you'll need. But again every project is different and you'll not find completely automated solution.
