Solo founders: What title do you give yourself?

What title should you represent yourself with when you're a one-man show?

Founder is usually best. The other options available:

• CEO: it makes the company sound much bigger than it is (which may or may not be your goal). A related one is "Founder & CEO"; which still sounds better than just "CEO".
• VP of something: misleading, but I've seen people use variations of this when contacting different people.
• Owner: for me it implies that you run a local store or something. Doesn't make you sound like you run a web-based startup.

There are official titles that you have to chose when incorporating, typically you are a President because someone needs to be. But on business cards and email signatures Founder is best. I feel like you reserve a CEO title for when you have at least one other C-level person on a team (like a CTO) and an actual team, otherwise it's a bit misleading. When you have large co-founding teams, use of VP titles makes sense to differentiate roles and responsibilities of the co-founders.
