Ideas are easy, Development is 99% of what being a company is all about -- the boring but much harder stuff. Unless you can show investors you've got the development sorted, your idea is worthless.
BTW: NZ no longer has patents on software, so don't even bother with patents if your business is software. If you can afford overseas patents then you are already a successful company and no longer a start up :)
Even if you do have patents, in the real world good development trumps a patent every time. Nobody ever got customers because of having a patent, but they sure did because they had a easy to use product, etc.
I am a patent attorney, so you can't tell me much about patents. NZ does currently have software patents and has done so for years. And will still have software patents under the new law. I agree that it is about execution, which is why I am looking for a developer to partner with. If you don't wanant to be part of something really big, at's fine. If you do, then contact me. I will tell you this: I have seen a lot of innovation and I Ihave learnt a lot about what works and what doesn't.
