Am I crazy to think I don’t need a “CTO”? “I will not promote”

I have always been a “technical” or “tech-savvy” person but I’ve never considered myself a programmer or engineer. With good reason, I don’t know how to actually write code. Like everyone else though, I’ve leveraged NLMs extensively for the past 12 months and I have created a full stack MERN web app. Hosted the front end on vercel and the back end on render. Mongo and Azure blob for storage. I have extensively QA’d the application for months and everything works. Deployed to production environments and all. I know and have documented client on-boarding processes (it’s multi-tenant), data migration and all of that. I’m going to market soon, have some initial seed funding. Am I crazy to think I don’t actually need a traditional CTO? I can build and fix bugs as I have been, and I know how to deploy the infrastructure. What am I missing here?
