Do you need a good team and interesting IDEA, better if you have product which work. And of course a start capital for marketing, site and managers. Good luck to your ideas
You definitely need a team, a real world use case for your product and time. I'm working on a project of my own during nights and its midnight before I know it. Getting little sleep is part of the process but I always wake up excited the next morning to keep going. If you have a good idea with a strong team behind you, you'll feel the same way.
