VP/Engineering (if you're an execution player) or VP/Product Management (if you're a vision player). Both of those titles are close to the revenue. In a small, focused startup, don't discount "lead developer with a board seat"; also a strong role.

If you're the tech founder in this scenario, the last thing you want to do is put yourself in the architecture ghetto. What will happen is that your company will then hire a VP/Eng and a VP/PM. You are in a very crappy place to compete for mindshare against Eng and PM from a CTO's desk.
