> I don't like the idea of having a partner or co-founder because I have put in 100% effort while others might not contribute equally.

I get it – I’ve felt the same when I was looking for a cofounder too. It’s tricky to find a person that’s passionate about the same thing as you are. But I think it’s still worth it to be looking for one.

Of course, you can also hire a marketing guy, or just ask around to see if you can barter (e.g. help them with something IT instead). But I think having a cofounder is still great for motivation – if you do find the right person, that is.
