Online Business Title?

[Tarek]

Hi, I currently run a small online business as a sole trader. I am 15 years old. I'm looking for a suitable title to add to my social media bio. What should I use?
"I am the owner of ..."
"I am the CEO of ..."
"I am the founder of ..."
Other (Please specify title)

Thanks for your time

I have run my own small business for over 20 years. First as a sole proprietor, then later I incorporated, so I understand your issue. Here's my thoughts on it:
You can be a founder of a business but no longer involved in it, so I would rule that out.
I don't think you can be CEO of something if it is not incorporated. Also, you can be the CEO but not the founder.

I think "owner" is the best. When you are a small business, "owner" implies you run everything so that seems like the best fit.
