@RUFUS MREHIN: I'm not sure you need a CTO right now, you do need another person to come in to help with ops. Don't turn away your cofounders/investors just because they are only offering money(success problem), look an see who makes a good strategic partner with access to large distributors and etc.
If you are a profitable trader I know it can be hard to give that up to do this full time. But look you need to see how often you are gonna get a chance to do something like this. The markets will always be there. Took me a very long time to learn that.
Me? I was cofounder of a fintech startup that folded. Push your idea hard.
