I am willing to bet that even the founders have felt that way at some point. I would say that you shouldn't take it as necessarily a permanent feeling, but part of the normal ebb and flow (until proven otherwise). As someone else mentioned, you should speak to your manager and stress the things you like. I would also try to determine beforehand what they could do to make you happy/engaged again. The more guidance you can give your manager, the better the chances that he/she can help you. And, remember, they want to keep you (assuming you are performing), and they prefer you happy, as it's better for them. Failing all of that, you might consider whether there is another company that can provide what you're seeking. Sometimes, it's just time to move on.
