Entrepreneurship isn't "We're going to defy ALL odds". You only pick the odds you can take on with your capital, time, effort and talent. If you win, you get to pick the next set of odds and so on.

Right now, it sounds like your team will have to learn entrepreneurship, product management (which is not the same as software development), software marketing, finance, sales, raising capital, alliances etc etc.

That's a LOT OF odds.
