I'm assuming you're already past the stage where you've verified the problem you're solving is worth solving with technology, otherwise you're wasting time. With that said, you need to divide responsibility. Either a 'CTO' role that has the decision to base the stack in his/her choice, or divide the tech up frontend/backend and give one person authority over each. When it comes to tech decisions, look at what you can work on fastest, secondary considerations can then be things such as your immediately available hiring pool, and what would gel easier with those people, and finally things like licensing.
