Similar to the advice about trying to find problems rather than solutions, I would look at existing businesses that are doing well, but aren't executing well.

Similar to the advice about trying to find problems rather than solutions, I would look at existing businesses that are doing well, but aren't executing well. The computer world is full of dominant products that were second to the market (despite what people think). Often teams have great ideas without great execution. You can capitalise on that and eat their lunch. And like others comments have said, I would also start thinking very critically about your self assessment of having a "great team". I could give you 10 viable business ideas before breakfast (actually, it is before breakfast for me!) Ideas are cheap to the point of being worthless. If you don't realise that, it's because you are likely inexperienced. This is not a criticism, just an observation. I would start by cashing one of those "blank cheques" and go looking for someone with experience who can help you. You are looking for someone technical who can give you sound advice about how to execute well building a product from end to end. You may be thinking that the technical person on your team is who you need. But what ever the academic credentials and how ever smart the person is, execution relies on having done it all before. It relies on having failed a hundred times before finally finding the one way that works. Finally, no matter if you follow my previous advice or not, begin by beginning. Like I said, good ideas are so common that they are worthless. You will either succeed through good execution or good luck. So start.
