Project manager would probably work for you just fine - have a look at the PMBOK for greater details on what that might entail.

Also it is worth considering that marketing is valuable to tech. Your post reminded me of this link, which is probably worth having a read: http://steveblank.com/2009/10/08/get-out-of-my-building/

If you want to persist in building tech, then the key is going to be for you to find a project of your own that you're really excited about so that you will be willing to stick with it through development of all the hard and annoying bits.

Thanks. What is the difference between a Product and Project Manager, from what you know?
