At the beginning of a startup, there are no "big tech decisions" per se, only a whittling down of your problem space and target market. If that can be done with zero technology, all the better.

What gets to be called a "startup" is highly debatable, as some billion-dollar companies have still been called "startups". However, you will only get to be faux-CTO if you get in really early, or start one yourself. Best of luck!
