I've started and registered my own company. I'm building a social network website with the same name all by myself.

What should be a proper title to put on my business cards? Founder, Owner, President, CEO.

I thought I should put Founder / Owner.

Thank you,

Whatever you want, it's up to you.

As it's your own company then Founder would fit best.

I don't put anything as far as who I am. Over the years I have found this to be best for reasons of my own such as 'why is the 'owner' taking care of these small details?' Leaving that part blank in my opinion is best. If they ask or if the proper moment arises, I tell them.

Yes, normally I leave the title blank, since if it is a small business you may fill many hats. I had one boss before, that never told anyone he was the owner,

You will get more sales people calling trying to sell the owner things than you get customer calls often, and often if they don't know you are the owner or main boss, you can make an excuse that you need to discuss a deal with someone, to give things a break at times

Depends how small your business is. If it you're the only employee then I wouldn't put any title on your business card. You'll be filling a lot of roles, and a title might seem a tad pretentious. It's possible to make it work, though. Plus if you say you're the owner, you'll get a lot of calls from salespeople.
